Noted for his work on oral diabetes treatment in Breslau and Leipzig; later at Tufts University, Boston.

The Breslau synagogue community address list (ca 1930) lists a medical doctor Martin Nothmann born 14.05.1894 and Minna Nothmann geb. Bergmann born 21.01.1896 living at Charlottenstrasse 32. The records of the annulment of their German nationality show that they subsequently lived in Leipzig.

Imprisoned in Buchenwald concentration camp on 10.11.1938, emigrated to the Netherlands on 05.04.1939 and to the USA in September 1939.

Sonja Delander identifies his father as Siegfried and Martin, born 1894, as the inventor of a synthetic oral diabetes treatment. Various works place him in Boston after the second world war. However Martin identifies his parents as Max Nothman and Amalie Wiener in a declaration made under the Law for the Restoration of the Professional Civil Service passed by the National Socialist regime on 7 April 1933 (thanks to SK, who viewed the document in an archive in Berlin, for this information). Furthermore, Martin's middle name, Mannheim, is the same as Amalie's father's name. Delander may have confused him with a contemporary namesake.

A 1939 passenger list records the arrival in New York on board a sailing from Rotterdam of:
- Martin Nothmann, 45, physician born in Kattowitz,
- Minna Nothmann, 43, housewife born in Rawitsch, and
- Evelore Nothmann, 17, born in Breslau,
all last permanently resident in Leipzig.

In the 1940 US census the family is listed in Ward 21, Boston, Boston City, Suffolk, MA.

Barbara Kowalzik describes his move with his wife and daughter first to London, where he had a medical practice, and then to New York where she says he died in 1950, despite saying a few lines before that he died in Boston in 1978.
