The Rat Pack is the nickname given to a group of popular entertainers most active between the mi-1950s and mid-1960s. Its most famous line-up featured Frank Sinatra, Dean Martin, Sammy Davis, Jr., Peter Lawford and Joey Bishop, who appeared together in films and on stage in the early-1960s. Despite its reputation as a masculine group, the Rat Pack did have female participants, including movie icons Shirley MacLaine, Lauren Bacall, Angie Dickinson, Marilyn Monroe, and Judy Garland.
