His father, whose original surname was Piñon, had distant Spanish ancestry.
Was a bombardier with the 8th Air Force during World War II.
Despite the claims that he was blacklisted during the McCarthy Era, he did actually work as an actor throughout the entire 1950s. But his job as television director was far more prosperous, and began in the 1960s.
He was the son of Elizabeth (Melincoff) and Maurice Penn, who were Jewish emigrants from Lithuania/the Russian Empire.
