Adrian Conan Doyle

Adrian Malcolm Conan Doyle (19 November 1910 – 3 June 1970) was the youngest son of Sir Arthur Conan Doyle and his second wife Jean, Lady Doyle or Lady Conan Doyle. He had two siblings, sister Jean Conan Doyle and brother Denis, as well as two half-siblings, sister Mary and brother Kingsley. Adrian has been depicted as a race-car driver, big-game hunter, explorer, and writer. Biographer Andrew Lycett calls him a "spendthrift playboy" who (with his brother Denis) "used the Conan Doyle estate as a milch-cow".He married Danish-born Anna Andersen, and was his father's literary executor after his mother died in 1940. He founded the Sir Arthur Conan Doyle Foundation in Switzerland in 1965. On his death, Jean took over as their father's literary executor.
