According to Stefan Kühl in For the Betterment of the Race (originally Die Internationale der Rassiten 1997), Sjögren was submissive to the Nazi party with their increasingly controversial views on eugenics, which contributed to the disintegration of the organization in the latter half of the 1930s.[4] Torsten Sjögren was professor of psychiatry at the Karolinska Institute from 1945 to 1961.
