Karloff, Boris (b. William Henry Pratt)
(1887–1969) actor; born in Dulwich, England. After years of touring as an actor in Canada (where he adopted his stage name) he settled in Hollywood in 1919 where he acted in silent films. His role as the monster in Frankenstein (1931) typecast him as a horror movie villain—in real life he was a gentle, refined person—and when he returned to the stage, as he occasionally did, it was also as some menacing character, such as Captain Hook in Peter Pan or the villainous brother in Arsenic and Old Lace. He also created the stereotype of the mad scientist in such movies as Isle of the Dead (1945).
