Sir John Maurice Laing (1 February 1918 – 22 February 2008) was a senior executive of British construction company John Laing plc. He was the first president of the Confederation of British Industry in 1965–66.
Laing was born in Carlisle, Cumberland, the younger son of Sir John Laing. The family were strict Christian Brethren. Laing's father had been running the family construction firm, John Laing & Son, since 1910, and Laing worked for the firm in his school holidays. The headquarters of the business moved from Carlisle to Mill Hill in 1926, and Laing was educated at St Lawrence College, Ramsgate.
In 1935, aged 17, he began to work full-time with his father at the family firm. Meanwhile, his elder brother, Sir William Kirby Laing, studied engineering at Cambridge University. After working as a trainee, he began managing the construction of new airfields and barrage balloon stations in 1938.
World War II
Despite his reserved occupation, and against his father's wishes, he joined the RAF during the Second World War. He initially served in the ranks, and was a Leading Aircraftman when he was commissioned as a Pilot Officer, RAFVR on 30 October 1943; he was promoted Flying Officer in April 1944. His wife's poor health due to tuberculosis delayed his training, but he qualified as a pilot in South Africa, and flew the second British glider across the Rhine.
