Kurt Freund (17 January 1914 – 23 October 1996) was a Czech-Canadian physician and sexologist best known for developing the penile plethysmograph (a measurement of sexual arousal in males), research studies in pedophilia, and for the "courtship disorder" hypothesis as a taxonomy of certain paraphilias (voyeurism, exhibitionism, toucherism, frotteurism, and what he called "preferential rape"). After unsuccessful attempts to change men's sexual orientation, he advocated against conversion therapy and in favor of the decriminalization of homosexuality.
