Gerald Brosseau Gardner (born 1884, died 1964), was one of the first and most famous individuals to be publicly associated with Witchcraft in the UK after it had been de-criminalised by the Fraudulent Mediums Act 1951. After a career as a Civil Servant, he retired in 1935 and became involved with various alternate life-styles. He later claimed that he was initiated into a Coven of Witches in 1939 in the New Forest, Hampshire. He was the founder and curator of the Museum of Witchcraft which was originally situated on the Isle of Mann and which opened in 1951. He was also the leader of his own coven and thus popularised (though not, he claimed, founded) the modern Wiccan movement, or more specifically, Gardnerian Wicca.
His most famous books are High Magic's Aid (1949) and Witchcraft Today (1951).
