A Dr Oskar Nothmann, court lawyer, born 15/02/1870, was deported from Berlin to Theresienstadt concentration camp on 18/03/1943. The 1939 census of Berlin does not list any other obvious family members at his address, Berlin Wilmersdorf, Pariser Strasse 53.

His relationship to his parents comes from a member's tree on jewishgen.org. It is supported by the facts that:
- in 1933 Dr Oskar Nothmann, brewery owner, reported the death of his sister Martha;
- like his sister and mother, he was born in Hamburg and like his sister and both parents he later lived in Berlin.
