Henry Havelock Ellis (1859–1939) was named after a distant relation on his mother's side, Henry Havelock, who participated in the Indian Rebellion of 1857. Following a private education and five years as a teacher in Australia, Ellis returned to England and entered St Thomas's Hospital, London, at the age of 21. Ellis never had his own medical practice, and didn’t practise beyond occasional general practice as a locum tenens. Ellis spent his days studying English art and literature. He collected facts about normal and abnormal sexual behaviour, and he published several books, including 'Studies in the Psychology of Sex' (1897–1928), 'Man and Woman, a study of human secondary sexual characters' (1889), and 'A Study of British Genius' (1904).
