A sex symbol in the 1940s, legendary husky-voiced actress Lauren Bacall lit up the big screen in countless classics, including To Have or Have Not, The Big Sleep, How to Marry a Millionaire, and Written on the Wind. She had an equally exciting time off-screen: Bacall was married to Humphrey Bogart until his death in 1957, had a high-profile affair with Frank Sinatra shortly thereafter, and was married to actor Jason Robards in the '60s.
