Sir John Wheeler Wheeler-Bennett GCVO CMG OBE FBA FRSL (13 October 1902 in Keston, Kent – 9 December 1975 in London) was a conservative English historian of German and diplomatic history, and the official biographer of King George VI. He was well known in his lifetime, and his interpretation of the role of the German Army influenced a number of British historians.
Wheeler-Bennett was born in Kent, the son of a prosperous importer. He was educated at Wellington House school in Westgate on Sea and then at Malvern College and did not regard his youth as a happy one. In the early 1920s he worked as an aide to Major-General Sir Neill Malcolm in the Middle East and Berlin, then from 1923 to 1924 was in the publicity department of the League of Nations in Geneva. After that, he was appointed as director of the information department of the Royal Institute of International Affairs and was editor of its Bulletin of International News between 1924 and 1932.
Wheeler-Bennett lived in Germany between 1927 and 1934 and witnessed at first-hand the final years of the Weimar Republic and the rise of Nazi Germany. During his time in Berlin, he became an unofficial agent and advisor to the British government on international events. He also enjoyed some success as a horse-breeder.
