Cannot make out his first name, but the surname is Kirsten.

Any chance of a close-up of the section with his name? Possibly Max Ferdinand???
It is Max Ferdinand Kirsten indeed. A married German national of Protestant faith, born 25 Jan. 1892 at Berlin as the son of Anna Kirsten who died the same year. Civilian occupation could be translated as "senior fitter" or "senior metal worker".
Awesome stuff. Thanks everyone!
