Sir Alfred Joseph Hitchcock, KBE (13 August 1899 – 29 April 1980) was a British filmmaker and producer who pioneered many techniques in the suspense and psychological thriller genres. After a successful career in his native United Kingdom in both silent films and early talkies, Hitchcock moved to Hollywood. In 1956 he became an American citizen while retaining his British citizenship.

Hitchcock directed more than fifty feature films in a career spanning six decades. He remains one of the most popular and most recognised filmmakers of all time. His image has endured partly due to cameo appearances in his own films and the series of television dramas he hosted, the eponymous Alfred Hitchcock Presents.
