Major George Derek Cooper OBE MC (28 May 1912 – 19 May 2007) was a British Army officer, campaigner for refugees, and supporter of the Palestinian people.
Cooper was born in Bromley in Kent. He was the third of four children of Captain George Stanley Cooper and his wife, Clara Tilling. The family were comfortably wealthy - the Coopers family were printers, and the Tillings owned a substantial omnibus company. His father was killed in Jhansi in India in 1915, while serving with the Royal West Kent Regiment.
He was educated at Kent House School in Eastbourne and then Eastbourne College. His mother married one of his father's fellow officers from India, Major George Dominic Heyland. The family moved to his estate in County Londonderry.
Cooper failed an eyesight test and so was unable to join the Royal Navy as he wished. Instead, he became an apprentice civil engineer in 1930, working in Greenwich for the Tilbury Contracting and Dredging Company. He was sent to Palestine in 1932, where a new harbour was being built at Haifa. He became a Special Constable in the Palestine Police, but returned to Ireland when the project was finished in 1934. His stepfather had died, and he ran the estate at Ballintemple.
