Trained as a musician, Virginia Gregg drew her first professional paychecks with the Pasadena Symphony. Gregg was sidetracked into radio in the 1940s, playing acting roles in an abundance of important California-based network programs. Her extensive radio credits include Gunsmoke, Suspense, Yours Truly Johnny Dollar, and Richard Diamond. Her first film was 1946's Notorious, directed by Alfred Hitchcock, who last cast Gregg as the voice of "Mother" in his classic chiller Psycho (1960). Virginia Gregg was most closely associated with the output of actor/producer/director Jack Webb: she co-starred in both of Webb's film versions of his popular radio and TV series Dragnet, and guest-starred in virtually every other episode of the 1967-70 Dragnet TV revival.
