Henry Havelock Ellis was an English physician, eugenicist, writer, progressive intellectual and social reformer who studied human sexuality. He co-wrote the first medical textbook in English on homosexuality in 1897, and also published works on a variety of sexual practices and inclinations, as well as on transgender psychology. He developed the notions of narcissism and autoeroticism, later adopted by psychoanalysis.
