Major Sir Desmond Morton (13 November 1891 – 31 July 1971) was a British military officer and government official.
Morton played an important role in organizing a response to appeasement of Germany under Adolf Hitler during the period prior to World War II by providing intelligence information about German re-armament to Winston Churchill.
At this time Churchill did not have any position in the government.
In 1940 Morton was Churchill's personal assistant when he became prime minister.
