Henry Havelock Ellis, known as Havelock Ellis (2 February 1859 – 8 July 1939), 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 is credited with introducing the notions of narcissism and autoeroticism, later adopted by psychoanalysis.

We forget that we ourselves are a part of history, that we are the product of growth and are condemned to perish if we lose the capacity for further growth and change. We are ourselves history and share the responsibility for world history and our position in it. But we gravely lack awareness of this responsibility.
