Franz Kallmann and Twin Studies

  • Patrick D. Hahn


This chapter details the career of Franz Kallmann, the German-born psychiatrist (and former protégé of Rüdin) who almost single-handedly founded the discipline of psychiatric eugenics in America—ironically, since he himself was forced to flee Nazi Germany to avoid persecution as an “undesirable” himself, due to his Jewish ancestry. This segues into a history of twin studies of schizophrenia, of which Kallmann was a pioneer, and a discussion of the fatal flaws underlying those studies.
