Carl Winter (1906–1966) was a British art historian and museum curator. He worked at the Victoria & Albert Museum's collection of English watercolours and miniature portraits before moving to the Fitzwilliam Museum in Cambridge in 1946 following the end of World War II.Along with Patrick Trevor-Roper and Peter Wildeblood, Winter gave evidence to the Wolfenden Committee, whose report led in 1967 to the decriminalization of sex between adult male homosexuals. He gave evidence anonymously as "Mr White". His testimony to the Committee has been portrayed on-screen in the BBC dramatisation, Consenting Adults.
