'''Henry Havelock Ellis''' (2 February 1859 – 8 July 1939) was an English physician, [[eugenicist]], writer, [[Progressivism|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]].

Ellis was among the pioneering investigators of [[psychedelic drugs]] and the author of one of the first written reports to the public about an experience with [[mescaline]], which he conducted on himself in 1896. He supported [[eugenics]] and served as one of 16 vice-presidents of the [[Eugenics Society]] from 1909 to 1912.<ref>{{citation |url=https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2986818/pdf/eugenrev00373-0002.pdf |title=The Eugenics Review |date=1913 |publisher=The Eugenics Education Society |pmc=2986818 |access-date=4 October 2021}}</ref>
