Doris Day (born Doris Mary Ann Kappelhoff; April 3, 1922 or 1924) is an American actress, singer, and animal rights activist. Day began her career as a big band singer in 1939. Her popularity began to rise after her first hit recording "Sentimental Journey", in 1945. After leaving Les Brown & His Band of Renown to embark on a solo career, Day started her long-lasting partnership with Columbia Records, which remained her only recording label. Over the course of her career, Day appeared in 39 films. She was ranked the biggest box-office star, the only woman appearing on that list in the era, for four years (1960, 1962, 1963 and 1964), ranking in the top 10 for ten years (1951–1952 and 1959–1966).
