Kurt Freund (17 January 1914–23 October 1996) was Czech-Canadian physician and sexologist known for developing phallometry (the objective measurement of sexual arousal in males) and research studies in pedophilia.
Freund was born into a German-speaking Jewish family in Chrudim, then part of Austrian Bohemia, later Czechoslovakia, now in the Czech Republic. He married Anna Hloun, a non-Jewish Czech pianist and music teacher, on January 13, 1942. In 1943, they divorced in order to protect Anna and their newborn daughter Helen from anti-Jewish and anti-miscegenation legislation implemented by the Nazis. They remarried after the war in 1945, and Anna gave birth to a son, Peter, in 1948. Many of Freund's relatives died during the Holocaust, including his parents Heinrich and Hella, and his brother Hans.
