9. Notes, sources, bibliography and abbrevations
In 1986 the forerunner of the Netherlands Institute for War Documentation (NIOD), the Netherlands State Institute for War Documentation, published De Dagboeken van Anne Frank (The Diary of Anne Frank: The Critical Edition, Doubleday, 1988/2003). This critical edition of the diaries of Anne Frank, edited by Harry Paape ( 2001), Gerrold van der Stroom and David Barnouw, included all of the diary entries by Anne Frank that were known at the time. The introduction contained a chapter on the background to the betrayal of the Frank family and the others who were in hiding with them. The conclusion was that it was impossible to identify the person who betrayed them.
In the meantime two books have appeared which each advance a new betrayal thesis: Melissa Müller, Anne Frank. De biografie (1998), and Carol Ann Lee, Het verborgen leven van Otto Frank [The hidden life of Otto Frank] (2002). The latter puts forward a blackmail hypothesis connected with the business activities of Anne’s father, Otto Frank.
The NIOD therefore decided to instigate a follow-up inquiry to look into two issues: a) an inventory of the betrayal hypotheses that have been mentioned to date and an evaluation of their probability or improbability, and b) the opportunities for blackmail during and after the war, partly in view of the role of Otto Frank in the business activities of Opekta, Pectacon and Gies & Co during and after the war.
Although our investigation focused on the three main suspects, that does not mean that we have overlooked other possible suspects (see Chapter 7).
We have made use of the same (archival) material as the authors of the two studies referred to above.
It is regrettable that two foundations that are in control of relevant archival documents, the Anne Frank Foundation in Amsterdam and (the president of) the Anne Frank Fonds in Basel do not (yet) have inventories of their archives at their disposal. This means that we do not know which archival documents there are or were. It is thus possible that as yet unknown material may turn up at a later stage.
The critical edition of De Dagboeken van Anne Frank already devoted dozens of pages to the possibility of betrayal by Van Maaren and to the arrest of the Jews in hiding. Melissa Müller has been the first author to look into another direction then Van Maaren. Her betrayal-theory is brief and we have treated her theory briefly too.
The largest part of the present study is devoted to a third betrayal thesis, and one that finds support in a large amount of source material: the thesis that Otto Frank and the others were betrayed by Tonny Ahlers. The possibility of blackmail has also been raised. It is therefore only natural that the main emphasis has come to rest on him.
An abridged version of this report will be incorporated in the next impression of De Dagboeken van Anne Frank. The footnote on page 381 of that work will also be amended. That footnote refers to a certain F.J. Piron as the buyer of Prinsengracht 263. However, his name was F.J. Pieron, and he sold the premises.
We are grateful to the authors mentioned above - Melissa Müller and Carol Ann Lee - with whom we have had regular contact, to the National Archive in The Hague, especially Sierk Plantinga and Nico van Horn, the Anne Frank Foundation in Amsterdam, especially Teresien da Silva and Yt Stoker, and the Anne Frank Fonds in Basel, especially its president Buddy Elias. In addition we owe a debt of gratitude to Anton Ahlers, Miep Gies, Paul Gies, Gerlof Langerijs, Jan Oegema, Eric Slot, Cor Suijk and J.W. Veraart. It is to be regretted that some of the relatives of one of the prime suspects refused to talk to us. In view of the fact that they have spoken to the media in the past, we consider that their refusal to talk to us has not seriously hindered the investigation.
2. Persecution of the Jews
Anti-semitic measures were gradually introduced under the German Occupation, but there were as yet no signs of a large-scale persecution.
Anne Frank summarized on July 20, 1942 the following ant-Jewish measures
Now that the Germans rule the roost here we are in real trouble, first there was rationing and everything had to be bought with coupons, then, during the two years they have been here, there have been all sorts of Jewish laws.
Jews must wear a yellow star; Jews must hand in their bicycles; Jews are banned from trams and are forbidden to use any car, even a private one. Jews are only allowed to do their shopping between three and five o'clock and then only in shops which bear the placard Jewish Shop; Jews may only use Jewish barbers; Jews must be indoors from eight o'clock in the evening until 6 o'clock in the morning; Jews are forbidden to visit theaters, cinemas and other places of entertainment; Jews may not go to swimming baths, nor to tennis courts, hockey fields or other sports grounds; Jews may not go rowing; Jews may not take part in public sports; Jews must not sit in their own or their friends' gardens after 8 o'clock in the evening; Jews may not visit Chris-tians; Jews must go to Jewish schools, and many more restrictions of a similar kind, so we could not do this and we were forbidden to do that.
During two raids in the centre of Amsterdam on 22 and 23 February 1941, more than four hundred Jewish men, most of them young, were captured and deported to Mauthausen. They were followed by a number of scattered raids in Amsterdam, in the eastern region of the country close to the German border, and in Arnhem, Apeldoorn and Zwolle. The first systematic calls to report started in the summer of 1942. Margot Frank, who was sixteen at the time, was one of the first group of a thousand persons, mainly German Jews, including a number of young people, who had received a registered call to report on Sunday 5 July 1942 from the Zentralstelle für jüdische Auswanderung. She was supposed to report there for work in Germany. This call forced Otto Frank to bring forward his well-prepared plan for going into hiding, and a day later the Frank family, Otto, his wife Edith and their daughters Margot and Anne found themselves in the ‘secret annex’ of Prinsengracht 263, the office and warehouse of Pectacon and Opekta. A few days later the Van Pels family, Hermann, Gusti and their son Peter, joined them, to be followed later still by the dentist Friedrich Pfeffer. They thus totalled eight Jews in hiding in the centre of Amsterdam.
There are no precise figures available on the number of Jews who went into hiding. The most recent estimate is 14,500.1 Nor can a picture be formed of ‘the’ Jew in hiding or what conditions were like, because the differences between individual cases are too large for that. One thing is certain: babies and small children who went into hiding had a high chance of survival, and it was rare for a whole family to go into hiding. It was very rare for a number of Jews - eight in this case - to go into hiding in the same place; most of those who did so moved from one hiding place to another in the course of time.
German security and police matters, including the persecution of the Jews, were run from The Hague, but Amsterdam, like other major cities, had its own Aussenstelle (Outpost) of the Sicherheitspolizei and the Sicherheitsdienst. This Aussenstelle was first established in Herengracht 485-487, but it eventually ended up in the High School for Girls, Euterpestraat 91-109. The members of the Aussenstelle were generally known as the Sicherheitsdienst (SD), but they were also called the Grüne Polizei because of their green uniform.
Willy Lages was in charge of this Aussenstelle from March 1941 to the end of the Occupation. From October 1944 on he was also formal head of the Zentralstelle für Jüdische Auswanderung that was to be set up.
The persecution of the Jews was not a priority at first, but measures to isolate and discriminate against the Jews slowly but surely got under way. The nazi organisations in the Netherlands included radical anti-Semites who engaged in anti-Semitic actions in the streets in an attempt to get the Germans to adopt a more active policy. However, the German apparatus set to work in a circumspect manner, especially after the February Strike in and around Amsterdam in 1941. A Zentralstelle für jüdische Auswanderung was set up in Amsterdam a month after those strikes; this mock-agency was to enable Jews to emigrate legally. The United States was not yet involved in the war and the Zentralstelle seemed to be a good solution. To make the façade even more attractive, the Jewish Council that had been set up in February 1941 was to install a liaison office - the Expositur - with this Zentralstelle. Numerous Dutch civil servants who were not nazis were involved in the preparation of all kinds of anti-Semitic measures.The same is true of the final implementation of the so-called Endlösung; hundreds of Dutch police, some nazis and some not, were involved in the raids, security services and tracking down Jews who had gone into hiding. Of course, whether their persecutors were nazis or not was hardly a concern of the victims.
More than 100,000 Jews were arrested in the Netherlands and deported between the first calls to report in July 1942 and the last large raid in Amsterdam on 29 September 1943. From October 1943 on policy was aimed at tracking down the remaining Jews in hiding and sending them to the exterminationcamps.
At this time the Zentralstelle für jüdische Auswanderung was housed in the Protestant High School in Adama van Scheltemaplein 1, but the premises were mainly used as an archive and canteen because the Zentralstelle did not really have any function after the end of 1943.2 Much more important and still extremely active was the Aussenstelle of the SD, located opposite the Zentralstelle in the High School for Girls.
The Germans were as interested in what the Jews owned as in the Jews themselves, and a large part of the value of their possessions was already transferred to the account of the Lippmann-Rosenthal bank before their deportation. The Germans also appropriated the contents of the houses that were now unoccupied. This activity was organised by the Hausraterfassung, which consisted of four divisions (Colonnes). One of those Colonnes, the Colonne Henneicke, named after the leader of this group, did not confine its activities from October 1942 onwards to registering the contents of vacant Jewish houses, but it turned into a group of hunters who were well paid for hunting Jews. Its members, operating in pairs, were active inside and outside Amsterdam until the end of 1943. Besides their regular pay, from March 1943 on they received a bonus for each Jew caught. The sum of ƒ 7.50 is often mentioned, but it could rise to a maximum of ƒ 40.3 A notorious hunter of Jews, Abraham Kaper, also head of IVB4 (Judenreferat) described this bounty as follows: ‘Initially it amounted to ƒ 2.50 per person, but this was later raised to ƒ 40. This money had to cover payment of informers and other expenses’.4 Whether the hunters of the Jews were German or Dutch, their hunt would not have been so successful without information or tip-offs about Jews in hiding. During one of his interrogations Kaper stated: ‘This office worked sporadically with so-called traitors. Reports came in, both signed and anonymous letters about Jewish activities, which led to the setting up of an inquiry’.5 No reliable statistics are available. ‘Actions were often carried out “on the basis of information received”, but there is no way of telling how many cases this involved.’6 We do have many postwar statements by members of the SD and their Dutch collaborators, but there is no tangible evidence such as betrayal notes or daily, weekly or monthly reports with names. That is probably due to a large extent to the fact that the Zentralstelle was used as an archive. That archive must have been destroyed when twenty-four British Typhoons bombarded both school buildings on Sunday November 19, 1944, half destroying the Zentralstelle and causing such damage to the SD headquarters that the SD had to move to the Apollofirst hotel. Dozens of homes were destroyed during this bombardment. In all probability, the loss to human life was fifty civilians and only four members of the SD.7 A lot of archival material was also destroyed by the SD during September 1944.8
3. Going into hiding and arrest in Prinsengracht 263
We have already mentioned that it was the calls to go and work in Germany on 5 July 1942 - Margot Frank had also received one - that prompted Otto Frank to bring forward the plans for him and his family to go into hiding. On Monday 6 July they closed the front door of Merwedeplein 37-II behind them, never to return. Anne wrote:
Not until we were in the street did father and mother tell me piece by piece about the entire plan for going into hiding. For months we had been moving as many of our possessions and clothes out of the house as we could, and now we had reached the stage of wanting to go voluntarily into hiding on 16 July. This summons made us bring the plan ten days forward, so that we would have to be content with less well arranged apartments.9
This case of going into hiding was not a typical one. Otto Frank and his family were refugees from Germany and thus did not belong to the Jewish-Dutch community, but Frank had many business contacts with non-Jews who would be able to help him.10 That was true not only of Miep Gies, Frank’s prop and stay, and her colleagues, but also of the Opekta representatives who visited the firm each week, and who had proposed to raise the money to buy the Franks’ freedom after the Sicherheitsdienst had raided the house.
Friday 4 August put an end to their period in hiding.11 A report had reached the SD Aussenstelle that there were Jews in hiding in Prinsengracht 263. According to his testimony in 1963 and 1964, SS-Oberscharführer (sergeant) Karl Joseph Silberbauer was notified of the fact by his superior Julius Dettmann. Even the number of Jews in hiding was specified. Dettmann was also alleged to have instructed Abraham Kaper, to send eight of his men with Silberbauer.
In fact, Silberbauer arrived from the Aussenstelle with at least three Dutch collaborators: Gezinus Gringhuis, Willem Grotendorst, and Maarten Kuiper. Accounts vary on what happened after their arrival. Wilhelm van Maaren and Lambert Hartog were working in the warehouse, Miep Gies, Bep Voskuijl, Johannes Kleiman and Victor Kugler were occupied in the front office. An important question is whether the SD knew the whereabouts of those in hiding - in the annex - or whether they just had the address Prinsengracht 263.
Otto Frank was the only person who could tell after the war what had taken place in the annex during the raid. After the war he stated, for instance, that when Silberbauer discovered that Frank had been a reserve lieutenant in the German army during the First World War, he was no longer in such a hurry. Of course he had time on his hands too because they had to wait for a larger car to take away the Jewish prisoners. This seems to indicate that the SD was not aware that there were eight people in hiding. Kleiman and Kugler were also arrested for assisting the Jews. Bep Voskuijl was able to leave without any difficulty, and Jan Gies, who followed his usual practice of arriving at the office around lunch time, was hastily sent away again by his wife. Silberbauer, who realised that Miep was from Vienna too, first called her a traitor to her country Austria, but he did not bother her any further. In 1964 he denied that Miep Gies had later tried to bribe him at the Aussenstelle.
4. Supplies to the Wehrmacht
During the first years of the German Occupation, the Dutch economy was flourishing thanks to German orders, an expanding public spending, and a stable level of production in the agricultural and service sectors. Even the loss of jobs due to the fall in exports to many countries, except Germany and the occupied territories, was compensated by 1941. There was even a regular drop in unemployment from June 1940 on.12 This was largely the product of German orders to Dutch companies, which amounted to 14% of the gross domestic product by the end of 1940. These were both military and civil orders, but in a Totaler Krieg, the direction in which the war was rapidly heading, that was not really a significant distinction. A Dutch company that supplied the Germans with semi-manufactured goods hardly knew (and probably did not want to know) whether those semi-manufactures were going to be used in the arms industry or not. Of course, a Dutch producer who supplied toothpaste to a German company could not know whether that toothpaste was destined for German soldiers.
In the Netherlands and in the other occupied territories, Berlin tried to organise all German orders through the Zentralauftragstelle (Zast) in order to have a clear picture of the transactions and to prevent prices from rising. Priority was to be given to military orders, but they were organised through the Rüstungsinspektion. The lists of companies that traded with the Germans via the Zast have been preserved.13 They show that in the period 1941-1942 no less than 1,500 Amsterdam firms were trading to a smaller or larger extent with the enemy.
As director of Opekta and Pectacon (the former dealt in pectin, the latter in the production of chemical products and foodstuffs), Otto Frank was directly affected by the anti-Jewish measures of the occupying forces from the autumn of 1940 on.14 Large and medium-sized ‘Jewish’ firms were Aryanized, sold or run by Dutch or German nazis. Small firms were taken over for liquidation. Various constructions were devised to avoid Aryanization or liquidation. One was to set up a ‘non-Jewish’ firm in good time, run by non-Jewish friends or acquaintances, that had taken over all the activities of ‘Jewish’ firms before the registration date. That was why La Synthèse was set up on 23 October 1940, which changed its name six months later to N.V. Handelsvereniging Gies & Co., a front organisation of friends (Kugler and Gies). The intention was that Pectacon would be incorporated temporarily to prevent the Germans from gaining control of it. However, the Germans saw through Otto Frank’s plans and an administrator was appointed for the liquidation of Pectacon. That was K.O.M. Wolters, a sollicitor and barrister in Amsterdam, an active member of the Dutch Nazi Party NSB, who acted for as much as nineteen Jewish firms as administrator and liquidator. However this sollicitor prefered the East Front and he got a military training in the beginning of 1943. Events followed a different course in the case of Opekta, because the mother company Pomosin in Frankfurt protected it - not to protect Frank, of course, but to prevent a Dutch rival from taking over the business.
As long as the raw materials were still available (in 1942 the Pomosin Werke in Frankfurt supplied 120 barrels of pectin, and in the following year 30,700 bottles of pectin) both Pectacon and Opekta - under other names - continued operations. Around 1941 Frank was no longer owner or director of the firms, which supplied the Germans just as did many others. It is unclear how large those supplies were and who the clients were. Frank’s firms do not appear in the Zast lists, which cover the period 1941-1944 and were drawn up by the Economic Investigation Service after the war.15
Nevertheless, it is known that the Wehrmacht was among the clients, for in the reminiscences that Miep Gies published in 1989 in collaboration with Alison Leslie Gold the following passage appears: ‘Our representatives travelled all over the Netherlands and continued to bring back orders to the Prinsengracht. Some of those orders were placed by German army camps in the country’.16 Miep Gies also writes that one of the regular customers was a German chef who had to cook for German troops: ‘He always paid cash and told Koophuis [Kleiman] that if we couldn’t get any food we should contact him’. He was based in Kampen, but in January 1945 Miep Gies cycled all the way there to see him and returned to Amsterdam with food.17
In Van Maaren’s testimony of 2 February 1948 he mentions ‘the German soldier from Naarden, a member of the SS, who received supplies and whom Mrs Gies and Mrs Brokx went to see in Kampen to fetch food supplies’. He goes on: ‘The company supplied a lot to the Wehrmacht throughout the Occupation through middlemen’.18
However, the Opekta profit and loss accounts for 1942, 1943 and 1944 do not contain any direct deliveries to the Wehrmacht. The Pectacon order book contains a record for 19 September 1940, when pepper and nutmeg (a total of 1,000 kg) were supplied to the Wehrmacht Verpflegungsamt in The Hague. This nursing unit’s activities included the purchase of food for the Wehrmacht. On another occasion it is clear that the company to which delivery was made was purchasing for the Wehrmacht or acting as a middleman. This was the NV Sunda Compagnie in The Hague, to which various items were to be supplied on 5 June 1940, according to the Pectacon order book. The delivery was to be made in accordance with the conditions laid down by the Oberkommando der Wehrmacht (OKW). In her account, Carol Ann Lee states that Otto Frank had delivered through middlemen to the Armee Oberkommando, ‘personally led by Hitler’.19 The name of Hitler has disappeared from the (American) Harper edition, but the Armee Oberkommando still plays its menacing role. It will not be possible to trace exactly how much in all was supplied to German firms or to the Wehrmacht.
5. Three suspects
For years Wim van Maaren, an employee of Opekta, was the only serious candidate suspected of betraying the eight in hiding in Prinsengracht 263. The names of two other suspects have been put forward in recent years: Lena Hartog-Van Bladeren (in 1998), and Tonny Ahlers (in 2002).
Investigations of the betrayal were concentrated in the immediate postwar period, in 1963/1964, and in the first half of the 1980s20 with respect to what actually happened during the German raid, and in particular the activities of the warehouse hand Van Maaren.
Wim van Maaren
Van Maaren was taken on in the spring of 1943. He was already viewed with distrust before the raid, because he was suspected of stealing from the warehouse and because he tried to find out who could have been in the warehouse at night. The fact that he was given the key to the premises by SS-Oberscharführer Silberbauer, who was in charge of the group that conducted the raid, thereby becoming de facto manager, is another ground for suspicion. He acted as manager until J. Kleiman, who had become director of Opekta and was arrested as an accomplice during the raid, returned. Kleiman had been detained in the camp in Amersfoort, but was released at the instigation of the Dutch Red Cross because he had become affected by a haemorrhage of the stomach. He was discharged on 18 September.
Soon after the Liberation, Kleiman wrote a letter to the Political Investigation Service (POD) to report Van Maaren’s petty theft and other minor crimes and to notify them that he would have known that there were Jews in hiding there. ‘When I asked him whether he knew that there were people in hiding in our premises, he replied that he only suspected it’, wrote Kleiman. The letter ended with the question as to whether there were sufficient grounds to question Van Maaren and the temporary warehouse hand Lammert Hartog.
No action was taken on the basis of the information contained in this letter for two years, until Otto Frank paid a visit to the Political Investigation Department (the PRA, the successor to the POD as of 1 January 1946) in Amsterdam at the end of June or the beginning of July 1947. The first witnesses were heard at the beginning of 1948. Kleiman had the following to say about the policemen involved in the raid: ‘They seemed to be completely aware of the situation, because they went straight to the hiding place’.21 Although Kleiman had not been there in person (he had remained downstairs), no further questions were asked on this point. Kleiman also stated that he had heard from Mr P.J. Genot (who worked for a different company with which Kleiman was connected) that Mrs Lena Hartog, who had worked as a cleaner at Pectacon for a short time, had told Anna Genot-Van Wijk that there were Jews in hiding in Prinsengracht 263. Mrs Genot-Van Wijk had replied that one should be careful about spreading such talk.
Mr and Mrs Genot-Van Wijk, who were questioned on 10 March 1948, confirmed what Kleiman had said. It further emerged that Genot himself had been to Prinsengracht 263 on several occasions, which was how he had got to know Van Maaren. They did not consider Hartog to be capable of treachery, and Genot found Van Maaren ‘a very strange sort of person and I did not know what to make of him’. Ten days later, Lammert Hartog told the PRA (Collobaration Investigation Unit) that Van Maaren had told him that there were Jews in hiding there two weeks before the raid. He also stated that the police who conducted the raid ‘did not have to look for Jews in hiding, but acted as though they were fully informed about the situation’. Unfortunately, the detectives forgot to ask him how he knew that.
Victor Kugler, deputy manager of Pectacon, who had been arrested together with Kleiman during the raid, merely stated on 14 January 1948 that ‘[we] suspect a certain Van Maaren’. He was not questioned any further about the raid, even though he had been on the spot.
Miep Gies was actually the most important witness at the time; she had remained behind with Van Maaren when the arrested persons were taken away, and either she must have given the keys to Van Maaren or Silberbauer must have taken them from her and given them to him. Her questioning indicates that she suspected Van Maaren of having good relations with the SD, since he was supposed to have stopped Silberbauer from having her arrested as well.22
Miep Gies was, without doubt, not happy about the fact that a simple warehouse hand had been made her superior through the intervention of the Germans. All the same, it seems logical, for why should Silberbauer have entrusted the firm to her care? He considered that Miep had become a traitor to her country (Austria), and believed that her husband had been an accomplice of the Jews.23 So there is no need to interpret the fact that Silberbauer appointed the male - undoubtedly an important factor at the time - warehouse hand Van Maaren, who was fourteen years older than Miep, as manager as a sign of Van Maaren’s guilt. When Kleiman resumed control at the end of October, Van Maaren did not put up any resistance; if he had been a friend of the SD, he could have incriminated Kleiman as an accomplice of the Jews to the SD in order to hang on to his attractive position. But he did not do so.
The PRA proceded to examine the material that had been collected, and concluded: ‘The betrayal is denied by the accused, and the evidence is very vague. The evidence is therefore not conclusive.’ The case was dropped on 22 May 1948. Six months later Van Maaren was given a conditional discharge, on condition that he would be put under the surveillance of the Political Delinquents Surveillance Department for three years, and that he could not enter the civil or the military service for ten years. He was also stripped of his active and passive right to vote during that period. Van Maaren successfully appealed. On 13 August 1949 he was given a full acquittal, because the magistrate did not consider the betrayal proven and declared the charges nullified.
In October 1963 it was discovered that Silberbauer, the member of the SD who had been in charge of the Prinsengracht raid, was at that moment police-officer in Vienna. By now the diary of Anne Frank had achieved international fame and the question of the betrayal was raised once more. The State Investigation Department in Amsterdam opened a new inquiry.
This inquiry was conducted more thoroughly than the inquiry held in the late 1940s, and the investigators were more professional than their predecessors had been. By now Kleiman and Hartog were dead and Kugler had emigrated to Canada. The other witnesses were questioned again, as well as Silberbauer and J.J. de Kok, who had worked as an assistant of Van Maaren for a few months in 1943. De Kok admitted that Van Maaren had committed thefts and that he had himself been involved, but he had never noticed any sympathy with the nazis on the part of Van Maaren. Bep Voskuijl, the younger colleague of Miep Gies, was questioned, but only stated that she had always been afraid of Van Maaren.
Miep Gies was naturally an important witness again. Her final statement during questioning was not very different from what the others had said:
Only the unsympathetic behaviour of the afore-mentioned Van Maaren and the contact that I had after their release with Mr Kleiman and Mr Kugler were reason for me to cast my suspicions to some degree in the direction of Van Maaren, without being able to provide you with sufficient facts and circumstances on the basis of which you could elaborate suspicions of him.
Willy Lages, who was still serving a life sentence in Breda prison (he was released in 1966 and died five years later), was questioned, but he had nothing of any importance to impart. Next his former subordinate Silberbauer was questioned. He stated that on the day in question he had received a phone call at the Aussenstelle from Dettmann, who told him that he had received a tip-off by telephone about eight Jews in Prinsengracht 263. Dettmann also instructed Kaper to take eight men with him to the Prinsengracht, he stated, but in the end Silberbauer and a number of his colleagues were dispatched. Silberbauer went on to state that when they arrived, they told the ‘Firmenchef’ (Kugler) that they knew that there were Jews in hiding, and that he immediately took them to the door behind the bookcase. Silberbauer denied that Miep Gies had visited him, but did not rule out the possibility that Van Maaren might have visited him on a couple of occasions. The last witness called was Van Maaren himself. This time he admitted to the thefts, but not to knowing that there were Jews in hiding there. According to him, there was ‘an air of mystery’ before the raid. It was Miep Gies, not Silberbauer, who had given him the keys, and Silberbauer had certainly not appointed him as Verwalter. This time there were more questions about Van Maaren’s background, and inquiries were conducted in his neighbourhood. The picture that emerged was that he was regarded as ‘financially unreliable’, but certainly did not have a reputation for being pro-German or sympathising with the nazis. The investigators were unable to find sufficient proof of the allegation of a neighbour that Van Maaren was a buyer for the Wehrmacht.
Van Maaren was not bothered by the justice any further.
Lena Hartog-Van Bladeren
The first serious biography of Anne Frank was published in 1998. In her Anne Frank. De biografie, Melissa Müller puts forward another suspect: Lena Hartog-Van Bladeren, the wife of Lammert Hartog, who had been a warehouse hand for Opekta from the spring of 1944 until August of the same year. Kleiman’s brother had a cleaning company, and she worked as a cleaner for that company as well as doing the cleaning at Prinsengracht 263. During questioning in the postwar period, Lena denied that she had ever worked at Prinsengracht 263, but Miep Gies stated that she certainly had, because she gave Bep Voskuijl the money to pay Lena for the cleaning. Lammert Hartog owed his job to Kleiman’s brother.
‘It is certain that Lammert Hartog told his wife Lena about the Jews in hiding’, Müller writes.24 According to Müller, Lena was seriously concerned about the safety of her husband and her son. She was worried about his safety because he worked where there were Jews in hiding, and she was worried about the safety of her son Klaas, who worked near Berlin through the Arbeitseinsatz before volunteering to join the Kriegsmarine. That is the reason, Müller argues, why it is plausible she made a phone call to the Germans on 4 August 1944 to tell them about the Jews in Prinsengracht 263. This is also in line with the ‘persistent rumours’ that it was a woman who had called. Müller’s comments on the questioning conducted in 1948 are in harmony with what we wrote in the introduction to De Dagboeken van Anne Frank. She suspects that it was the poor quality of that questioning which enabled Lena to evade detection. Since Lena died on 10 June 1963, she could not be questioned a second time.
In 2002 the English researcher Carol Ann Lee, nowadays a resident of Amsterdam, put forward the third and latest theory about the betrayal of the Jews in hiding in Prinsengracht 263. Four years earlier she had published a biography of Anne Frank, Pluk rozen op aarde en vergeet mij niet. Anne Frank 1929-1945 [Pluck roses on the earth and do not forget me. Anne Frank 1929-1945], followed in 2002 by her Het verborgen leven van Otto Frank [The hidden life of Otto Frank]. This ominous title is accounted for by a part of her book, in which she argues that Otto Frank was in the clutches of his betrayer right down to his death. All the same, the title does not cover the full contents of the book, because Het verborgen leven van Otto Frank has the character of a double biography: it presents the biographies of both Otto Frank and his alleged betrayer Tonny Ahlers. This is certainly legitimate from Lee’s point of view, because she argues that their lives were closely intertwined: ‘they had a history together’.25 What is Lee’s version of the events?
In March 1941 a brief conversation took place in the Rokin in Amsterdam between Otto Frank and J.M. Jansen about the course of the war. Joseph Jansen had been a stand constructor for Frank’s Opekta firm in the past and was married to a demonstrator from the same company. Frank expressed his doubts about the German chances of victory to Jansen.26
Next month, on 18 April 1941, a certain A.C. (Tonny) Ahlers appeared in Frank’s office. The two men did not know one another. Ahlers had a letter with him that Jansen had written to the head of the NSB with a request to pass it on to the SS. When Ahlers showed the letter to Frank, he recognised Jansen’s handwriting. The letter described his conversation with Jansen of the previous month. Ahlers (a member of the NSB since the summer of 1940, and a member of the more radical Nazi Party (the NSNAP) since October of that year)27 had apparently intercepted the letter, though it was unclear how he had done so. Frank gave Ahlers a sum of money then and once again on a later occasion, and subsequently stated that he never saw Ahlers again during the war.28 Lee contradicts this last statement: ‘According to Ahlers, that first meeting in Otto’s private office was the start of regular visits’.29 In the English and US editions of her The hidden life, this has been expanded to become ‘according to Ahlers and other witnesses’.30
Jansen’s letter of betrayal has not been found. Ahlers left it with Frank, who showed it to Kugler and Miep, and later to his solicitor Dunselman. Dunselman took a few notes, filed the letter, and later destroyed it.31
The ‘highly anti-Semitic’32 Ahlers was a regular visitor to the SD in Amsterdam during the war. The SD enabled him to move into a house that had previously been occupied by Jews in November 1943. It was near the office of the SD-Aussenstelle in the southern district of Amsterdam. His neighbours included all kinds of members of the SD (Döring, Rühl, Viebahn) and an Abwehr agent (Rouwendal). For some time Ahlers worked for the man who had been put in charge of Frank’s firm by the Germans, the solicitor K.O.M. Wolters. Ahlers had previously had his own small company dealing in sugar products and raw materials in 1941. He needed suppliers for this Wehrmacht Einkauf Büro PTN (Petoma). He found them, according to his widow, in the person of Otto Frank; first of all Ahlers received payment for keeping his mouth shut about Jansen’s letter, and later he is supposed to have been supplied with raw materials for his business by Frank.33 How long those deliveries lasted and how they were made ‘is unclear’.34 It was probably through his work in the office of Verwalter Wolters that Ahlers found out about the legal smoke-screen that Frank had been obliged to put up around the ‘Aryanization’ of his companies in 1940/1941.35
In 1963/1964 Ahlers stated that he knew about deliveries by Otto Frank’s companies to the Wehrmacht.36 He added that he ‘permitted’ Frank to go into hiding.37 Ahlers’ knowledge of those deliveries to the Wehrmacht would make Frank vulnerable to blackmail after the war too, and (according to his relatives) Ahlers made use of that until long after the war was over.
Ahlers was detained a month after the German capitulation. He was suspected, among other things, of having acted as an informer for the SD.38 Soon after Otto Frank’s return from Auschwitz, Lee claims, he came into contact with Ahlers once more: Frank wrote the name ‘Ahlers’ twice in his appointments diary in July 1945. Lee argues that he ‘must’ have visited Ahlers in the prison in Scheveningen at that time,39 but tones this down to ‘presumably so’ in the English edition,40 where she adds in parenthesis that the contact might also have been through Ahlers’ wife.41 In the following month, on 21 August 1945, Frank sent an incriminating letter concerning their meeting in April 1941 to the Bureau for National Security (BNV). He did the same in November 1945 to an unknown addressee.42
According to Lee, Ahlers had Otto Frank in his clutches: after all, Ahlers knew about the deliveries to the Wehrmacht, about the - enforced - dismissal of a Jewish employee from Opekta, about members of the NSB who had remained in service, about the wartime profit, and about the fact that Frank was a stateless ‘German’, which could lead to confiscation of his business because of his ‘enemy nationality’.43
This situation worsens even more when Lee goes on to state that Ahlers was not only blackmailing Frank, but that he was also indirectly the betrayer of Otto Frank. When the betrayal of Anne Frank in particular attracted media attention in 1963 because of the arrest of the Austrian member of the SD Silberbauer, Ahlers sent the judicial authorities in Vienna a letter in which he claimed, among other things: ‘Otto Frank collaborated with the nazis during the war and certainly cannot be seen as an example of what his coreligionaries went through in Nazi Germany’.44 Ahlers also sent a letter to Silberbauer himself.45 Those letters indicate that Ahlers ‘permitted’46 Frank to go into hiding, and that - according to Lee - Ahlers knew that Frank used his annex as a hiding place.47 Ahlers, she claims, had seen that there was an annex behind Prinsengracht 263 when he visited Frank in April 1941.48 Moreover, in 1938 his mother lived on the first floor of Prinsengracht 253, a house with an annex too.49 Ahlers lived there with her ‘for several months’.50
In the autumn of 1944 Ahlers was going through a bad patch: his firm went bankrupt,51 he could no longer make use of deliveries by Frank’s firm, he was in financial trouble, and he could use the bounty that he would receive for bringing in a Jew. Although Ahlers moved to Nieuwer-Amstel (Amstelveen) in April 1944,52 he was afraid of Abwehr agent Herman Rouwendal, who rented a room in his house in Amsterdam. Ahlers went to the SD for protection and wanted to get in their good books.53 Though she refuses to commit herself entirely, Lee ‘believes’54 that this combination of circumstances, fuelled by Ahlers’ anti-Semitism, led him to tell his friend and example, Maarten Kuiper from the SD, about the situation in Prinsengracht 263. Kuiper phoned Dettmann.55 According to Ahlers’ brother Cas, it was Tonny Ahlers himself who phoned Dettmann,56 who then called Kaper of IVB4. It was Kaper who sent Silberbauer and his men to the address they had been given. So even if the phone call to the SD did not come from Ahlers himself, the incriminating information did.
In December 1945 Otto Frank was still trying to find the person who had betrayed his family and the others who had gone into hiding with them.57 In the same month he discovered that Ahlers had betrayed others and wanted ‘nothing more to do with him’.58 It seems doubtful whether Frank ever suspected Ahlers of betraying Prinsengracht 263.59 Later he claimed to be no longer interested in the detection of the culprit. According to the letters that Ahlers sent in the 1960s, this was because Frank himself had a lot to hide.60 Ahlers knew about that, and according to the sources used by Lee in 2002, Ahlers used his knowledge to extort money from Frank after he moved to Switzerland in 1952.61 In the third version of her book, the US edition of 2003, Lee comes to the conclusion that this blackmail started in the mid-1960s, because in 1958 Frank still believed that Ahlers had saved his life in 1941 and because from 1963 on Ahlers sent his incriminatory letters to Vienna.62 This blackmail, she claims, continued until Otto Frank’s death in 1980.63
This last revelation is not to be found in the first version of Lee’s book, which appeared in Dutch in March 2002. This is because various witnesses from the Ahlers family contacted Lee after the publication of that book. Naturally, she has incorporated their reminiscences in the later editions of her book: the English edition, released in the autumn of 2002, and the US edition that came out in early 2003.64 We shall not refer to all three publications in the following sections except where it is relevant to do so. This is important because Lee has taken advantage of the publication of new editions to modify her original text and argument. It is only natural for her to do so. The fact that the first version of her book, which was published in Dutch, is a translation of her original English manuscript is irrelevant since the Dutch edition appeared several months before the English one. An Afterword in the English edition contains an account of Lee’s investigations after the publication of the Dutch edition.65 These have mainly been incorporated in the body of the text in the recent US edition.66
The main problem in contemporary history is often not the lack of historical material, but its abundance, which is often too much to mention. That is not the case with the present inquiry; on the contrary, the sources are scanty and contradict one another. The scarcity of sources is partly due to the bombardment of 19 November 1944 of the Zentralstelle, which was used among other things as an archival depot, and to the fact that the SD most probably destroyed incriminating evidence in September 1944. Most of what is available today comes from postwar interrogations of members of the SD and other involved parties. The reliability of the testimonies of actors and the professionalism of the interrogators play an important part. The name of Anne Frank is not mentioned in the interrogations of members of the SD; this is only natural, one might suppose, since she had not achieved fame at that time, but by the time of the interrogations after the discovery of Silberbauer this was no longer the case. However, they naturally had a lot to hide and welcomed the opportunity to pass the responsibility on to a colleague. Little information is provided on specific matters because in most cases the accused continue to deny the charges. The general tenor of the cases emerges clearly enough, although the amount of bounty paid, for example, varies considerably, as we have seen. This can be an important factor, since it plays a role in the hypothesis of betrayal by Ahlers. It is regrettable that the interrogations of 1948 stopped where they did, because some stories are evidently second-hand.
If the different hypotheses are considered, the following analyses can be made.
Though he was hardly popular among those in close proximity to him, Van Maaren was not pro-German or pro-nazi, nor did he show any signs of anti-Semitism. It is only natural that his thefts should have aroused the suspicions and fears of those in hiding in the annex and their accomplices, but those directly involved, those accomplices, were unable to come forward with facts that point to betrayal. That was also the view taken by the Political Investigation Department. What is noteworthy, however, is the fact that he appealed against his conditional discharge and was fully acquitted. If he really had been the culprit and had (indirectly) had seven deaths on his conscience, he would surely have been satisfied with the conditional discharge. When the case was reopened in 1963, very little new material emerged.
The State Investigation Department closed the Van Maaren dossier on 4 November 1964. It was sent to the Public Prosecutor with an accompanying letter which stated that ‘the inquiry has not been able to lead to any tangible result’. Investigator A.J. van Helden went on to list five factors which lent support to Van Maaren’s innocence: (1) Van Maaren refused on principle to support Winterhulp-Nederland, an organisation with nazi leanings that had the monopoly of charity; (2) Van Maaren did not know the people in hiding, so there could be no question of his bearing them a grudge; (3) Van Maaren was in financial trouble, but there is no evidence of the payment of a bounty for betrayal; (4) Van Maaren helped to ensure that parts of Anne’s diary were in safe keeping, while he could easily have given it to the SD; (5) Van Maaren was not viewed sympathetically by neighbours who had been members of the Resistance, but he did not seem like the betrayer of Jews in hiding. And although he knew about Resistance activities in his neighbourhood, he had never informed the Germans.67
However, not everyone was convinced of his innocence. For instance, in 1964 Kugler wrote about him to Miep Gies: ‘It is bad enough to have the death of 7 people on his conscience and to be responsible for the troubles that the other three went through during a certain period’.68
More than ten years later, Otto Frank wrote in a letter that Van Maaren could not be prosecuted ‘as there is no evidence’.69
Melissa Müller bases her reconstruction on a number of premises. Two weeks before the raid Lammert Hartog knew that the Jews were in hiding there,70 but the claim that ‘it is certain that Lammert Hartog told his wife Lena about the Jews in hiding’71 cannot be substantiated.
If she was so worried about the fate of her husband, why did she phone the SD at the moment when he was working in the Frank warehouse? At any rate, during his questioning by the Political Investigation Department, Lammert was able to tell what happened during the raid, and he continued to work there for a further ‘three or four days’.72 On the other hand, there is the statement by Kleiman, who told the same department that Hartog ‘already had his coat on when the SD arrived. He left immediately and we have not seen him since’.73
What can have been the connection between such an act of betrayal and the fate of her son? He had joined the Kriegsmarine as a volunteer on 22 August 1944 and she had probably not heard from him for some time. But on the date when she is accused of having called the SD, there was nothing the matter with her son. It was not until seven years after the war that official notice of his death was issued by the Standesamt 1 in Berlin, which gave his date of death as ‘Anfang Mai 1945, Tag nicht bekannt’. However much latitude that date may allow, there can be no question of Lena’s having foreseen in August 1944 the death of her son almost nine months later.
The ordinary procedure followed in the Euterpestraat does not indicates that a phone call from an unknown person - we assume that Lena Hartog was unknown there - would have led to direct action.
The ‘persistent rumours’ that it was a woman’s voice that was heard on the line go back to a remark by Cor Suijk, former member of the board of the Anne Frank Foundation and a confidant of Otto Frank. He had heard it from Frank a long time ago. Frank’s widow, Elfriede Frank Markovits, stated shortly before her death in October 1998 that it had been a woman’s voice. She had it on the authority of her husband.74 There is no indication of how Otto Frank came by that information. Cor Suijk contributed substantially to the book by Melissa Müller, and it is conceivable that Melissa Müller took the woman’s voice as a premise in searching for an appropriate suspect.
Carol Ann Lee’s elaborate theory certainly compels respect for its cleverness. She combines a determined drive to find the truth with a great ability to make connections. What is at stake here, however, is the question of whether her theory is valid. Given the complexity and wealth of detail of her book, it is useful at this point to break her theory down into three components: (1) contacts between Ahlers and Otto Frank; (2) blackmail of Frank by Ahlers; and (3) betrayal of Prinsengracht 263 by Ahlers.
1. Contacts between Ahlers and Otto Frank
a Contacts in April 1941 - The visit by Ahlers to Otto Frank on 18 April 1941 is an established fact. Frank himself referred it.75 Lee rightly points out that Otto Frank gave ‘different versions’76 of it that diverge on minor points, such as the amount of money involved, but which corroborate one another on the main points.
b Contacts during the rest of the war - While Ahlers received money ‘when they met for the first time’ in exchange for keeping his mouth shut about Jansen’s letter’,77 ‘later on Frank supplied him with material for his business instead’.78 According to Ahlers79 ‘and other witnesses’80, that first meeting in Frank’s private office was certainly not the last: it was claimed that it was followed by regular visits.81 In 1945 Frank stated that they were confined to that first (and probably a second) meeting in April 1941. Otto Frank wrote at the time: ‘I have not seen him [Ahlers] since’.82 On the basis of the statements of Ahlers and those ‘other witnesses’, Lee concludes that Frank’s statements on the matter are ‘lies’,83 and later in her book she writes that it was an ‘uncommon lie’.84 In the discussion that we had with Lee on 27 September 2002, she admitted that this was a translation error: the English text states that Frank ‘was prevaricating’,85 and the ‘uncommon lie’ has been toned down to ‘not the only curiosity’.86 Frank had at least been prevaricating. Had he? The course of events in the summer of 1945 makes it clear that Frank had had contact with someone at least then (i.e. in the summer of 1945) about Ahlers, though it is unclear whether that contact was actually with Ahlers himself. But what went on during the war? Did Ahlers pay ‘regular visits’ to Otto Frank?
‘Ahlers and other witnesses’
As mentioned earlier, Lee backs up her argument by referring to ‘Ahlers and other witnesses’.87 Since neither the Dutch publisher Balans (Boek 2002) nor the English publisher Viking/Penguin (Book 2002) provided Lees’ book with proper notes, in the first instance we had to resort to a computer print with source references (Ms.) that Lee has deposited with the Anne Frank Foundation in Amsterdam so that those interested can verify her sources. It is only since the spring of 2003 that we have a published set of footnotes at our disposal in the US edition published by HarperCollins (Harper 2003).
In her computer print, Lee refers to a letter of Ahlers of 20 December 1964 for Ahlers,88 though no source is given in the US edition.89 As Lee told us, the letter of Ahlers from 1966 was addressed to the Dutch weekly Revue.90
Ahlers’ letters of 1963, 1964 and 1966
From the citations that Lee has published,91 it was already clear that Ahlers’ letter of 1966 is largely a reprise of the letter that he sent to in Vienna in 1963 and of the letter that he sent to Silberbauer in the following year.92 There have been copies of these letters in the NIOD since the 1960s, and since they are a prime source for Lee, we cite the latter in extenso:
‘I [Ahlers] have had to visit Otto Frank on several occasions at his address Prinsengracht 263 (annex) since the date of 18 April 1941 to urge him to go into hiding. In those days every Jew went into hiding immediately after a warning. Not Otto Frank. He supplied his Pectine products to the German Wehrmacht, and has members of the NSB in his employ, especially his travelling rep and standdresser Jansen. This Dutch National Socialist (NSB) was member number 29992. His son was also employed by Frank/Opekta, and his activities included work in the warehouse... In Frank’s letter dated 21 August 1945, a date on which there was no question of a so-called ‘Annex’ [the Dutch title of the diary], Frank positively identified the Jansens in his employ as his betrayers. When this matter hit the international press a few months ago, Otto Frank impudently kept silent about this. I know exactly why. But nevertheless this man allowed himself to be called “honest” and “representative”. The question is only: of what?’93
It looks as though the first sentence (‘had to visit Otto Frank on several occasions’) is the first clue that led Lee to believe that Ahlers and Frank also had contact with one another after April 1941. The content of Frank’s postwar letter referred to by Ahlers will be discussed below, as will the intriguing use of the plural in the words ‘the Jansens in his employ as his betrayers’; but for the time being we are primarily concerned with the period leading up to the German capitulation.
In his letter of 1966, Ahlers goes a step further in declaring that Otto Frank ‘at any rate should [have] announce[d] his knowledge about the most likely warehouse assistant/traitor Jansen junior’.He also stated that Frank
‘sold the Pectin products to the German Wehrmacht and others. As a preservative, Pectin was urgently needed in the German war industry, for which many Dutch companies were deployed too. [...] In my opinion Frank received his raw materials directly from Berlin.’
The fact that Opekta did not avoid supplying the Germans has been discussed above, and of course it is true that many Dutch companies did something similar (including Ahlers’ own business). Frank’s Opekta did not receive raw materials ‘directly from Berlin’, but from another German city, Frankfurt, from the mother company Pomosin Werke. In his letter Ahlers explained the fact that the Frank family ‘did not go into hiding until July 1942’ from the false sense of security that Frank had felt until then from the ‘NSB/Wehrmacht relation/supply etc. etc.’.
‘A business arrangement’ during the war
Lee claims that during the war Ahlers and Frank concluded ‘a business deal by which Frank supplied Ahlers’ firm’.94 It ‘is not clear’ how these supplies were organised or how long they lasted. They are supposed to have taken place in exchange for Ahlers’ silence about Jansen’s letter. As the source for these allegations Lee cites his widow Martha96 and Ahlers’ family.97 The extant archival documents of Frank’s firms do not contain any clue that might confirm the existence of such deliveries.
The reliability of Ahlers as a source
Lee refers in this connection to ‘all the available documents’.98 In fact they all appear to go back to a single source: Tonny Ahlers.
As far as reliability is concerned, it is not just appearances that are against Tonny Ahlers. He let his imagination run away with him. The Political Investigation Department (PRA) in Amsterdam wrote in 1948: ‘Whoever is questioned about the suspect [Ahlers] describes him as a boaster whose imagination runs away with him and who likes to pretend that he is big and important’. Ahlers was said to display ‘great imagination and a lot of idle talk’. The impression that Ahlers had made on an investigator of the Political Investigation Service (POD, the forerunner of the PRA) was ‘that he is a big braggart, very stupid and capable of anything’.99 The PRA concluded its report with the remark ‘that the suspect [Ahlers] is very difficult to pin down on anything’.
‘He has very long stories about all kinds of minor matters and is constantly showing off by mentioning the names of various authorities and bodies. When you try to go more deeply into the matter, it does not go anywhere and all you get is yet more stories.’100
Fifteen years later, in connection with the letters that Ahlers had sent to Austria at the time of the Silberbauer affair, the Dutch State Investigation Department opened up an inquiry on him. He was probably visited ‘a couple of times’ in the winter of 1963/1964.101 The State Investigator Van Helden stated in his report: ‘This Ahlers [...] is an imaginative person, who does not distinguish between truth and fantasy very clearly. His behaviour during the war bordered on criminal deception’. Lee took Ahlers’ testimonies seriously in 2002 and 2003.102 In the 1980s the director of the Netherlands State Institute for War Documentation, Harry Paape, did not in the light of investigator Van Helden’s remarks.103 That is why this Ahlers does not appear in the chapter on the betrayal [‘Het verraad’] in De Dagboeken van Anne Frank (1986, 2001).
Ahlers’ brother and son said very unpleasant things about Ahlers after the appearance of Lee’s book,104 but they do not call him a blatant fantasist. Lee herself is explicit about this: ‘And although he [Ahlers] was indeed a storyteller, his tales always had some basis in truth’.105 We would have welcomed the opportunity to discuss this with the main members of the Ahlers family to verify this, but unfortunately most of them refused.106
The sources of Carol Ann Lee
As stated above, the testimonies before us essentially go back to one and the same source: Tonny Ahlers and his family. There are convincing indications that Ahlers himself was not reliable. This is a central argument against the validity of Lee’s theory. Is her theory perhaps supported by Ahlers’ relatives? We have been unable to interview the widow, brother or eldest son. Lee has interviewed the widow Martha and the brother Cas - although the second contact between Martha and Lee in particular does not appear to have run smoothly.107 However that may be, we are dependent on what Lee has recorded them as saying. Ahlers’ youngest son, Anton, was born soon after the German capitulation. Of course, he may subsequently have made use of all kinds of sources of information for what he knows about the behaviour of his father during the war, but during our interview with him it became evident that he had eavesdropped or been told what he knew by his father.108 There is no indication in the written sources (such as the business administration) that Otto Frank actually did business with Ahlers during the war. In our view, this has in no way been proven, or even made plausible. The same applies to the alleged contacts between the two men after April 1941. In this reflect, we are bound to conclude that Lee has relied on source material that is too one-sided.
c Contacts in the summer/autumn of 1945 - Otto Frank’s first letter - What is beyond doubt, on the other hand, are the steps that Otto Frank took to Ahlers in 1945. On 24 July 1945 Frank asked the prison authorities in The Hague for the correct address to which to send information about Ahlers. Frank had discovered ‘incidentally’ that Ahlers was ‘currently interned’. The prison authorities scribbled Ahlers’ cell number, 769, on the envelope and apparently returned the letter, since it is now in the possession of Anne’s cousin Buddy Elias in Basel, where Lee found it.109 We also examined this piece of evidence there and found out more: on the back of the envelope is written: ‘Correspondence not permitted’. Lee does not mention this detail. At the bottom of Frank’s own letter the prison director wrote that he should contact the BNV. Frank did so a month later.
Otto Frank’s second letter
On 21 August 1945 Otto Frank wrote a letter to the Bureau for National Security (BNV), a predecessor of the National Security Service (BVD, today the General Intelligence and Security Service, AIVD), and one of its first postwar priorities was to track down collaborators and traitors to their country.110 So Frank approached the right authorities.
He wrote to the Bureau that he ‘happened’ to have heard ‘that Mr A.C. Ahlers, v.d. Hoochlaan 24 in Amstelveen’ was detained ‘in the prison, v. Alkemadelaan 850, The Hague, cell 769’. He then devoted a page and a half to the incident with Jansen in the Rokin in 1941 and the visit by Ahlers a month later. Nowhere does Frank ‘positively’ identify Jansen as his betrayer, as Ahlers was to claim in his letters to Vienna in 1963/1964. (Or the incident of 1941 should be viewed as betrayal; but it did not have any harmful effects. The telephone call of betrayal was made in 1944.) Frank concluded his letter:
‘I felt obliged to inform you of the above, in view of the fact that I believe that Mr Ahlers saved my life at that time, for if this letter had reached the hands of the SS, I would have been arrested and killed long ago.
As already stated, I know nothing else about this young man.’111
Apparently Frank had discovered in the meantime exactly where Ahlers was living in the Van de Hoochlaan in Amstelveen. Lee writes ‘and yet [Otto Frank] recalled Ahlers’s full name and address from “one” meeting in 1941’.112 Lee ignores the fact that Ahlers was still living in Amsterdam in 1941; he did not move to Amstelveen until April 1944, a fact that can only have reached Frank’s ears later.
That very same day Frank sent the Political Investigation Service in Amsterdam a copy of the letter that he sent to Scheveningen about Alders. In the note that accompanied it Frank urged them to put Jansen ‘behind bars’. Jansen was arrested. Partly in connection with the 1941 incident, he was sentenced in 1941 to four and a half years’ imprisonment.113
Otto Frank’s third letter
On 27 November 1945 Frank wrote yet another letter - the third - this time to an unknown addressee, in which he once again described the intervention of ‘Alers’ (sic). This time Frank added:
‘When Mr Alhers came out of prison a few months ago, he visited me and told me how everything had turned out.
