Lauren, who was best known for her husky voice and smouldering stare, had a Hollywood career that spanned a remarkable seven decades.
Born Betty Joan Perske in Brooklyn, New York, in 1924, she made her silver screen debut at the age of 19 in To Have and Have Not, opposite her future husband Humphrey Bogart.

That film also gave her one of her most memorable lines – "You don't have to act with me, Steve. You don't have to say anything and you don't have to do anything. Oh, maybe just whistle. You know how to whistle, don't you, Steve? You just put your lips together and… blow."
