Roger Moore was born on 14 October 1927 in Stockwell, London. He was the only child of George Alfred Moore, a policeman (PC168E based in Bow Street, London), and Lillian "Lily" (Pope). His mother was born in Calcutta, India, to an English family. He attended Battersea Grammar School, but was evacuated to Holsworthy, Devon, during World War II, and attended Launceston College in Cornwall. He was further educated at Dr Challoner's Grammar School in Amersham, Buckinghamshire.
Moore apprenticed at an animation studio, but was fired after he made a mistake with some animation cells. When his father investigated a robbery at the home of film director Brian Desmond Hurst, Moore was introduced to the director and hired as an extra for the 1945 film Caesar and Cleopatra. While there, Moore attracted an off-camera female fan following, and Hurst decided to pay Moore's fees at the Royal Academy of Dramatic Art. Moore spent three terms at RADA, where he was a classmate of his future Bond co-star Lois Maxwell, the original Miss Moneypenny. During this time there, he developed the Mid-Atlantic accent and relaxed demeanour that became his screen persona.
At 18, shortly after the end of World War II, Moore was conscripted for national service. On 21 September 1946, he was commissioned into the Royal Army Service Corps as a second lieutenant. He was given the service number 372394. He was an officer in the Combined Services Entertainment section and eventually became a captain, commanding a small depot in West Germany. He later looked after entertainers for the armed forces passing through Hamburg.
