Rat Pack
The 1960s version of the group included Frank Sinatra, Dean Martin, Sammy Davis, Jr., Joey Bishop, Peter Lawford (brother-in-law of John F. Kennedy), and for a brief stint, Norman Fell. Angie Dickinson, Juliet Prowse, and Shirley MacLaine were often referred to as the "Rat Pack Mascots", a title which reportedly made these ladies feel like "one of the boys".
The post-Bogart version of the group was reportedly never called that name by any of its members - they called it the Summit or the Clan. "The Rat Pack" was a term used by journalists and outsiders, although it remains the lasting name for the group.
The Rat Pack often performed in Las Vegas, Nevada, and were instrumental in the rise of Las Vegas as a popular entertainment destination.
They played an important role in the desegregation of Las Vegas hotels and casinos in the early 1960s. Sinatra and the others would refuse to play in or patronize those establishments that would not give full service to African American entertainers including Davis.
Once Rat Pack appearances became popular and the subject of media attention, the Las Vegas properties were forced to abandon segregation-based policies.
