Ralph Follett Wigram CMG (/ˈreɪf ˈwɪɡrəm/; 23 October 1890 – 31 December 1936) was a British government official in the Foreign Office. He helped raise the alarm about German re-armament under Hitler during the period prior to World War II.
In part, he did this by providing intelligence information about German re-armament to Winston Churchill at a time when Churchill did not hold a position in the government of Stanley Baldwin. Churchill used the information to publicly attack the policies of Baldwin. Churchill's magisterial six-volume history of World War II, The Second World War, described Wigram as a "great unsung hero." The autobiography of Valentine Lawford, who worked under Wigram in the Central Department, describes him variously as "the authentic local deity" and "the departmental volcano."
Wigram's role was brought to public attention by the Southern Television drama serial Winston Churchill: The Wilderness Years (in which he was portrayed by Paul Freeman), and later by the biographical movie about Churchill, The Gathering Storm (in which he was portrayed by Linus Roache).
Wigram was the son of Eustace Rochester Wigram and Mary Grace Bradford-Atkinson, and had a younger sister, Isabel. He was the grandson of the Right Reverend Joseph Cotton Wigram, Bishop of Rochester, younger son of Sir Robert Wigram, 1st Baronet. He was a second cousin of Lord Wigram. He was educated at Eton and University College, Oxford.
