Leopold Frommer

Leopold Frommer (born January 15, 1894 in Leipzig , † January 27, 1943 in Slough , Berkshire ) was a German engineer.

Life and activity

Leopold Frommer came from a Polish-Jewish family. He grew up in Germany and, after attending school, studied physics and mechanical engineering at the University of Jena and at the Technical University of Berlin from 1913 . He completed his studies in early 1922 as a graduate engineer.

From 1922 to 1925, Frommer worked for the Berlin industrial company Ludwig Loewe, where he dealt with ways of establishing the aluminum injection molding process. In 1926 he received his doctorate at the TH Berlin with a thesis supervised by Georg Schlesinger and Hermann Föttinger for Dr. Ing.

From 1926 to 1933 Frommer was employed at the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry , where he was Michael Polanyi aside. Shortly after the National Socialists came to power in the spring of 1933, he was dismissed in April 1933 by the director of the institute with effect from July of the same year due to his Jewish descent. After finishing his work there, he went to Great Britain.

In Great Britain Frommer worked as a researcher in the research laboratories of High Duty Alloys, Ltd., Slough.

After his emigration, Frommer was classified by the National Socialist police as an enemy of the state: In the spring of 1940, the Reich Main Security Office in Berlin placed him on the special wanted list GB , a list of people who would be succeeded by the occupying forces in the event of a successful invasion and occupation of the British Isles by the Wehrmacht Special SS commandos were to be identified and arrested with special priority.

He died in 1943 as a result of an operation.
