Victor Christian William Cavendish, 9th Duke of Devonshire, governor general of Canada 1916-21 (b at London, Eng 31 May 1868; d at Chatsworth House, Derbyshire, Eng 6 May 1938). The youngest member in the British House of Commons in 1891, he remained there until 1908, when he succeeded to the dukedom. Retiring, deliberate and a pedestrian speaker, he was easy to underestimate as governor general. But he travelled widely, was politically helpful and was the soul of constitutional propriety. There were none of the problems there had been with his predecessor, the duke of Connaught.

As one of Britain's great landowners, he took a particular interest in Canadian agriculture. After returning home, he served briefly as secretary of state for the colonies. His wife was the daughter of the marquess of Lansdowne, governor general in the 1880s. Their son-in-law, Harold Macmillan, provides an affectionate portrait of Devonshire in the first volume of his memoirs, Winds of Change (1966).
