Fritz van Emden

Isidore Fritz van Emden (born October 3, 1898 in Amsterdam , † September 2, 1958 in London ) was a German-British entomologist.

Life and activity

Emden moved to Germany with his family in 1900. After attending school, he studied natural sciences at the University of Leipzig from 1918 to 1922 . In 1921 he completed a doctorate from Johannes Meisenheimer supervised work for parental care for Dr. rer. nat. He passed the state examination and briefly taught at the Nicolai School in Leipzig , but then turned to a career as an entomologist.

Van Emden first worked with Walther Horn at the German Entomological Institute in Berlin and later in Halle. On April 1, 1927, he was hired as a curator for entomology at the State Museum for Animal Science and Ethnology in Dresden.

After the National Socialists came to power in the spring of 1933, Emden was removed from civil service on September 30, 1939 due to its Jewish descent (half-Jewish) according to the National Socialist definition .

In 1936 van Emden moved to Great Britain. There he lived initially on a grant from the Society for the Protection of Science and Learning . In November 1937 he found employment as a taxinomist at the Imperial Institute of Entomology . There he was researching flies (calyptrate Diptera). In his private life, however, his main interest was the beetles, on which he carried out extensive research in his spare time and published numerous papers in specialist journals. The larval system of insects (especially the beetles) was his specialty.

After his emigration, the National Socialist police officers classified Van Emden as an enemy of the state: In the spring of 1940, the Reich Main Security Office in Berlin put him on the special wanted list GB , a directory of people who would be removed from the occupation forces in the event of a successful invasion and occupation of the British Isles by the Wehrmacht Subsequent SS special commands were to be identified and arrested with special priority.
