John Houseman (September 22, 1902 - October 31, 1988) was an English-American actor and film producer who became known for his highly publicized collaboration with director Orson Welles from their days in the Federal Theatre Project through to the production of Citizen Kane. But he is perhaps best known for his role as Professor Charles Kingsfield in the TV series The Paper Chase and for his commercials for the brokerage firm Smith Barney.
