Humphrey Bogart was born into an upper-class family in New York in 1899. Wounded in service during World War One, he played romantic Broadway leads in the 1920s before going to Hollywood in the 1930s and slowly rising to prominence in a series of films that included High Sierra, The Maltese Falcon and The Big Sleep. Latterly, he became an iconic figure – the lone wolf, a cynical, super-cool, unruffled man of integrity in a murky, amoral world. He died of throat cancer in 1957.
Lauren Bacall was born Betty Joan Perske, also in New York, in 1924. After being spotted by Howard Hawks on the cover of Harper’s Bazaar in 1943, he chose her the following year to star opposite Bogart (who she later married) in To Have and Have Not. Still only 19, in that film she exhibited a dry, silky worldliness that belied her youth, famously asking Bogart in her husky voice, ‘You know how to whistle donth’cha Steve? You just put your lips together and blow.’ She is still acting.
