German hygienic physician and professor at the Hamburg State Institute of Hygiene.
From 1 May 1933 to 30 November 1934 he was a member of the Nazi Party. In November 1933 he signed the confession of the German professors to Adolf Hitler. At the end of March 1938 he had to return his teaching license because his mother was of Jewish descent as part of the Mendelssohn family. The University of Hamburg reinstated him in June 1945 and awarded him an honorary doctorate in 1954.
He died on 5 November 1962, aged 85.
