S. S. Van Dine is the pseudonym used by American art critic Willard Huntington Wright (October 15, 1888 – April 11, 1939) when he wrote detective novels. Wright was an important figure in avant-garde cultural circles in pre-World War I New York, and under the pseudonym (which he originally used to conceal his identity) he created the immensely popular Philo Vance character, one of the most influential detectives in American mystery fiction and, in turn, in film and radio as well.
