William Hopper (born William DeWolf Hopper Jr.; January 26, 1915 – March 6, 1970) was an American actor who, despite being the son of Hollywood royalty—actor DeWolf Hopper and powerful columnist Hedda Hopper—carved out his own distinct and iconic legacy on screen. After a prolific start in the 1930s and 40s with appearances in over 80 films, he served in the U.S. Navy during World War II and subsequently left the acting profession. He was lured back to the screen in the 1950s by director William Wellman, a move that led to the defining role of his career: the cool and capable private investigator Paul Drake in the classic CBS television series Perry Mason, a part that immortalized him in one of television’s most enduring dramas.
