James David Graham Niven (ˈnɪvən; 1 March 1910 – 29 July 1983) was a British actor, soldier, memoirist, and novelist. Niven was known as a handsome and debonair leading man in Classic Hollywood films. He received an Academy Award and a Golden Globe Award.
Born in central London to an upper-middle-class family, Niven attended Heatherdown Preparatory School and Stowe School before gaining a place at the Royal Military College, Sandhurst. After Sandhurst, he joined the British Army and was commissioned as a second lieutenant in the Highland Light Infantry. Upon developing an interest in acting, he found a role as an extra in the British film There Goes the Bride (1932). Bored with the peacetime army, he resigned his commission in 1933, relocated to New York, then travelled to Hollywood. There, he hired an agent and had several small parts in films through 1935, including a non-speaking role in Metro-Goldwyn-Mayer's Mutiny on the Bounty (1935). This helped him gain a contract with Samuel Goldwyn.
Parts, initially small, in major motion pictures followed, including Dodsworth (1936), The Charge of the Light Brigade (1936), and The Prisoner of Zenda (1937). By 1938, he was starring as a leading man in films such as Wuthering Heights (1939). Upon the outbreak of the Second World War, Niven returned to Britain and rejoined the army, being recommissioned as a lieutenant. In 1942, he co-starred in the morale-building film about the development of the renowned Supermarine Spitfire fighter plane, The First of the Few (1942).
He went on to receive the Academy Award for Best Actor for his role in Separate Tables (1958). Other notable films during this time period include A Matter of Life and Death (1946) which appears on many critical lists as the best ever British made movie, The Bishop's Wife (1947), Enchantment (1948), The Elusive Pimpernel (1950), The Moon Is Blue (1953), Around the World in 80 Days (1956), My Man Godfrey (1957), The Guns of Navarone (1961), Murder by Death (1976), and Death on the Nile (1978).
