Sigmund Freud
From BoyWiki
Sigmund Freud was an Austrian neurologist, now known as the father of psychoanalysis. In 1935, he wrote "Homosexuality is assuredly no advantage, but it is nothing to be ashamed of, no vice, no degradation; it cannot be classified as an illness; we consider it to be a variation of the sexual function, produced by a certain arrest of sexual development".
