John Buchan (1875 - 1940) was a Scottish novelist, historian and Unionist politician who served as Governor General of Canada, the 15th since Canadian Confederation. After a brief legal career, Buchan simultaneously began his writing career and his political and diplomatic careers, serving as a private secretary to the colonial administrator of various colonies in southern Africa. He eventually wrote propaganda for the British war effort in the First World War. Buchan was in 1927 elected Member of Parliament for the Combined Scottish Universities, but he spent most of his time on his writing career, notably writing The Thirty-Nine Steps and other adventure fiction.
