New Jersey-born Henry O'Neill was a year into his college education when he dropped out to join a traveling theatrical troupe. His career interrupted by WWI, O'Neill returned to the stage in 1919, where his prematurely grey hair and dignified demeanor assured him authoritative roles as lawyers, doctors, and business executives (though his first stage success was as the rough-and-tumble Paddy in Eugene O'Neill's The Hairy Ape). In films from 1933, O'Neill spent the better part of his movie career at Warner Bros. and MGM, usually playing parts requiring kindliness and understanding, but he was equally as effective in villainous assignments. Age and illness required Henry O'Neill to cut down on his film commitments in the 1950s, though he frequently showed up on the many TV anthology series of the era.
