From Wikipedia, the free encyclopedia. Albert David Hedison, Jr. (born May 20, 1927, Providence, Rhode Island) is an Armenian-American film, television, and stage actor. He was billed as Al Hedison in his early film work. In 1959, when he was cast in the role of Victor Sebastian in the short-lived espionage television series Five Fingers, NBC insisted that he change his name. It was proposed that he use his middle name and he has been known as David Hedison ever since.
