Reedy, balding, often bespectacled American character actor with pencil-thin moustache, once described as the man with TV's 'most deceptive face'. He looked like - and was - a certified public accountant, graduate from Northeastern University. A struggling actor in his youth, he worked in stock, tent shows and on radio. After army service in World War II, he became a prolific performer in early anthology series on television stand out in particular. Severe spinal deterioration brought about Vaughn's retirement from acting in 1976. His wife of many years, Ruth Moss, a fellow graduate of the Leland Powers School, was a noted Boston radio personality and Broadway actress.
Most famous for playing Janet Leighs boss in Alfred Hitchcocks "Psycho".
Was the first "guilty" character on Perry Mason.
