Havelock Ellis (1859–1939) was working as a teacher in Australia, when he had a revelation that he wanted to dedicate his life to exploring the issue of sexuality. He returned to London in 1879 and enrolled in St. Thomas’s Hospital Medical School. He began to write, and in 1896 he co-authored "Sexual Inversion" with John Addington Symonds. The book was first published in German, and a year later it was translated into English. Their book explored homosexual relationships, and in a progressive approach for their time they refused to criminalize or pathologize the acts and emotions that were present in homosexual relationships.
