Henry Havelock Ellis, known as Havelock Ellis , was an English physician, writer, progressive intellectual and social reformer who studied human sexuality. He was coauthor of 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 transgender psychology. He is credited with introducing the notions of narcissism and autoeroticism, later adopted by psychoanalysis. He served as president of the Galton Institute and, like many intellectuals of his era, supported eugenics.
Ellis, son of Edward Peppen Ellis and Susannah Mary Wheatley, was born in Croydon, Surrey . He had four sisters, none of whom married. His father was a sea captain, his mother the daughter of a sea captain, and many other relatives lived on or near the sea. When he was seven his father took him on one of his voyages, during which they called at Sydney, Callao and Antwerp. After his return, Ellis attended the French and German College near Wimbledon, and afterward attended a school in Mitcham.
