Trenchard, Hugh Montague Trenchard, 1st Viscount, 1873–1956, British air marshal. He entered the army in 1893 and served in the South African War. During World War I he commanded the Royal Flying Corps. As chief of air staff (1918, 1919–29), Trenchard shaped the offensive air strategy (to the neglect of air defense) that the Royal Air Force adhered to into World War II. He was (1931–35) commissioner of the London police force and was created a peer in 1936.
