William George Constable (born Derby, England, 27 October 1887, died Cambridge, Massachusetts, 3 February 1976, was an art historian and gallery director.  He was the father of  Medieval Historian Giles Constable.

Education
Distantly related to the landscape painter John Constable, William George Constable was educated at Derby School, where his father was headmaster, and St John's College, Cambridge, where he read history, law and economics. In 1909, he was awarded the Whewell Scholarship for International Law. After gaining a First in economics in 1910, he was awarded the McMahon Law Studentship by St John's for four years, then entered the Inner Temple and was called to the Bar in May, 1914.

War Service
During the First World War, Constable served in the Sherwood Foresters for two years, but he suffered severe shell shock when a shell exploded in a trench a few feet from him, burying him alive. He then spent a long period in a nursing home while recovering.

Fellow of St John's College, Cambridge
While convalescing, Constable reworked and resubmitted an existing thesis to St John's and was elected a Fellow of the College, a position he held from January 1919 to the end of 1921.

Art career
From 1921, Constable attended the Slade School of Art in London, worked at the Wallace Collection. In 1923, he joined the National Gallery, where he stayed for eight years, the last two as assistant director, and became an art critic for the New Statesman and the Saturday Review. In 1931, he moved to the newly formed Courtauld Institute of Art at the University of London, having been recruited as its first Director by Arthur Lee, 1st Viscount Lee of Fareham. In 1935, he succeeded Roger Fry as Slade Professor of Fine Art at the University of Cambridge, while continuing as Director of the Courtauld. In 1937, he resigned both positions and in 1938 left England to become Curator of the Boston Museum of Fine Arts. He remained in the United States until his death in 1976.
