Major-General Sir Ernest Dunlop Swinton, KBE, CB, DSO (21 October 1868 – 15 January 1951) was a British Army officer who played a part in the development and adoption of the tank during the First World War. He was also a war correspondent and author of several short stories on military themes. He is credited, along with fellow officer Lieutenant-Colonel Walter Dally Jones, with having initiated the use of the word "tank" as a code-name for the first tracked, armoured fighting vehicles.
