John Buchan, 1st Baron Tweedsmuir PC GCMG GCVO CH 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 both his writing career and his political and diplomatic career, 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. Once he was back in civilian life Buchan was 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. In 1935 he was appointed Governor General of Canada by George V, king of Canada, on the recommendation of Prime Minister of Canada Richard Bennett, to replace the Earl of Bessborough. He occupied the post until his death in 1940. Buchan proved to be enthusiastic about literacy, as well as the evolution of Canadian culture, and he received a state funeral in Canada before his ashes were returned to the United Kingdom.
You think that a wall as solid as the earth separates civilization from barbarism. I tell you the division is a thread, a sheet of glass. A touch here, a push there, and you bring back the reign of Saturn.
