Identification of Politician with Hindenburg 1926

[JoeW]

This photo from a book on Konrad Adenauer shows a visit by President Hindenburg in March 1926. Can anyone identify the two men to the left and right of him in the photo? I keep thinking I have seen the man on the left of the President before. Wire rim glasses and what appears to be a mustache? Was he in the Prussian government? Thank you in advance for any assistance.

Would the man on the left be Prussian Minister of Interior Severing?

Here is a the same photo from Alamy. Below photo of Carl Severing from Bundesarchiv.
Severing attended the event and gave a speech as well as Hindenburg and Adenauer (on the right).

Is this who you are thinking of?

Probably NOT him.

No, not a young Trotsky. Too many history books over the years. Guess they are no-bodies, as no one has recognized them.

Person on the left could be Vizepräsident Johannes Bell , on the right Ministerpräsident Otto Braun (note eyebrows !)
Both attended this event on March 21st in Cologne.
