John Barrymore (born John Sidney Blyth; 1882–1942) was an American actor of stage, screen and radio who appeared in more than 40 plays, 60 films and 100 radio shows. He was the youngest child of the actors Maurice Barrymore and Georgie Drew Barrymore, and his two siblings were Lionel and Ethel; together they were known as America's "Royal Family" of actors, and John was "perhaps the most influential and idolized actor of his day", according to his biographer Martin F. Norden.
