John Buchan, 1st Baron Tweedsmuir, 26 August 1875 - 11 February 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 administrator of various colonies in southern Africa. He eventually wrote propaganda for the British war effort during World War I. He was elected Member of Parliament for the Combined Scottish Universities in 1927, but he spent most of his time on his writing career, notably writing The Thirty-Nine Steps and other adventure fiction. In 1935, King George V, on the advice of Prime Minister R. B. Bennett, appointed Buchan to replace the Earl of Bessborough as Governor General of Canada, for which purpose Buchan was raised to the peerage. He occupied the post until his death in 1940.Buchan was enthusiastic about literacy and the development of Canadian culture, and he received a state funeral in Canada before his ashes were returned to the United Kingdom Buchan was born in Perth, Scotland, the first child of John Buchan-a Free Church of Scotland minister-and Helen Jane Buchan. He was brought up in Kirkcaldy, Fife, and spent many summer holidays with his maternal grandparents in Broughton in the Scottish Borders. There he developed a love for walking and for the local scenery and wildlife, both of which are often featured in his novels. The protagonist in several of his books is Sir Edward Leithen, whose name is borrowed from the Leithen Water, a tributary of the River Tweed.
