The 1966 book 'Born Free: A Lioness of Two Worlds' tells the story of Elsa, a lioness born in the wilds of Kenya. The book was written by Joy ADAMSON and her husband George ADAMSON, who raised Elsa from a cub and released her back into the wild. The book was later adapted into an Academy Award-winning film of the same name, which starred Virginia McKenna and Bill Travers as Joy and George ADAMSON. The film follows the true story of Elsa, who was born free in the wilds of Kenya and was later adopted by the Adamsons, who gave her the name Elsa, derived from the acronym NEE (Nothing Else Exists).
