Vincent Leonard Price, Jr. was a actor, well known for his roles in horror
films. His first venture into the genre was in the 1939 Boris Karloff film
Tower of London. 

The longest-running and best known radio incarnation of Simon Templar
as The Saint was Vincent Price, who played the character in a long-running
series that was broadcast between 1947 and 1951 on no fewer than three
networks: CBS, Mutual and NBC. After Price left the series in May 1951, he
was replaced by Tom Conway.
