Hans Graaz, M.D.
	(1879-1953) Natural health practitioner, eugenicist and lifestyle reformer, nudist Graaz was a gymnast, coppersmith, masseur, and therapeutic bath specialist before studying medicine and becoming a doctor in 1920. He started working at the Institute in 1923 and was the head of the eugenics department for a year. Graaz was primarily involved in consultation, with a focus on reproduction hygiene. Within this scope, he gave advice on eugenic "mating" choices and marriage. In 1924, he turned his attention to his special field of interest: nudism. He became medical director at a "therapeutic school of nudism" where Magnus Hirschfeld and Karl Besser were also employed. In addition, he worked as a natural health practitioner.
