John Alexander(1897-1982)

Making his stage debut at age 16, John Alexander joined a Shakespearean repertory company and in 1917 appeared on Broadway in "The Merchant of Venice." Although he played many parts on both stage and in films, his best known role was that of the crazed Teddy Brewster--the son who thinks he's Theodore Roosevelt - in Arsenic and Old Lace (1944), a part he played both on stage and in the movie.
