The forced migration process of German-speaking neurologists and psychiatrists under the Nazis during the 1930s and 40s is often preoccupied solely with "successful" concepts and therapeutic approaches. The case of German-Canadian neurologist Karl Stern (1906-1975) is very instructive, however, since the process of forced migration, for him, proved to be a transitionary process from his former cutting edge work in neuropathology and holist neurology in Germany to clinical psychiatry and the development of the new discipline of geriatric medicine in Canada.
