The Rat Pack is the nickname given to a group of popular entertainers most active between the mid-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 of people, the Rat Pack did have female participants, such as movie icons Shirley Mac Laine, Lauren Bacall, and Judy Garland.
