Leonard (Leo) Cooper (born March 25 1934, died November 29 2013) worked for numerous distinguished publishing houses before setting up his own independent publishing house, Leo Cooper Ltd, in 1968.
Leo was eduacted at Radley where he took charge of the military band and distinguished himself on the rugby and cricket fields. He was capped at cricket for the Yorkshire schoolboys; in later life he smashed Denis Compton for six with such vigour that he toppled a spectator sitting in a wheelchair into a nearby pond.
His publishing business was based upon monumental works such as Lord Anglesey's eight-volume History of the British Cavalry (1973-95) and the Famous Regiments series, he was always on the look out for what George Orwell called "unofficial history", such as Antonia Hunt's Little Resistance (1982), the extraordinary story of an English schoolgirl's experiences in German-occupied France.
In 1970 the Leo Cooper Ltd merged with the long-established firm of Seeley Service, which was in turn bought by Frederick Warne in 1979 after the company went into receivership and then in 1982 he moved under the happier umbrella of Secker & Warburg, then part of the Heinemann Group. In 1990 the firm was sold to the Barnsley Chronicle and renamed Pen & Sword Books.
Leo married the author Jilly Cooper in 1961 following the break-up of his first marriage to Diana his former housemaster's daughter. The couple had known each other since 1945 (when Jilly Sallitt was about eight), although they did not marry until she was 24 and he was 27. In the 1980s, the couple left Putney, London for The Chantry, an old manor house in Gloucestershire. The couple were unable to have children naturally so adopted two children. They also had five grandchildren. Leo Cooper was diagnosed with Parkinson's disease in 2001.
