The former Betty Joan Perske sashayed her way through any number of classic roles, though she said herself that her skill as an actress was frequently overshadowed by her relationship with Humphrey Bogart.
That said, to call the pair's onscreen chemistry "palpable" would be an understatement. "Everyone could see their love right there on celluloid," their son Stephen Bogart told PEOPLE in 1996. "He was the great love of her life, and she his."
We've rounded up our favorite scenes of the two sharing the screen below.
To Have and Have Not (1944)
Phew. What more is there to say about this clip, currently popping up in every Bacall piece online today? No wonder Bogey fell hard.
The Big Sleep (1946)
Though the film wasn't a big critical success, it's hard to argue with the pair's chemistry.
Dark Passage (1947)
Interestingly, while the 1981 song "Key Largo" may have directly referenced Bogart and Bacall, "I Guess I'll Have to Change My Plan" may be a more appropriate song for the couple: It appears in both The Big Sleep and Dark Passage.
Key Largo (1948)
This was the pair's last co-starring film together before Bogart's death in 1957.
The footage isn't from a film – it's (unfortunately soundless) 8mm footage of the pair on their yacht Santana in 1949, from the Academy of Motion Picture Arts and Sciences' film archive.
