Sir Alfred Joseph Hitchcock KBE (1899-1980) was an iconic and highly influential film director and producer, who pioneered many techniques in the suspense and thriller genres. Following a very substantial career in his native Britain in both silent films and talkies, Hitchcock moved to Hollywood and became an American citizen with dual nationality in 1956, thus he also remained a British subject. Hitchcock directed more than fifty feature films in a career which spanned six decades, from the silent film era, through the invention of sound films, and far into the era of colour films. For a complete list of his films, see Alfred Hitchcock filmography. Hitchcock was among the most consistently recognizable directors to the general public, and was one of the most successful film directors during his lifetime. He continues to be one of the best known and most popular filmmakers of all time.
