Simon David Davan Sainsbury (1 March 1930 – 27 September 2006) was a British businessman, philanthropist and art collector.
A keen sportsman, he was selected for the Eton-Harrow match at Lord's in 1947 as a bowler; sent in as a nightwatchman, he scored a century.
[1][3] After National Service as "sports officer" in the Life Guards, he studied history at Trinity College, Cambridge.
He and his brothers funded an extension to the National Gallery, London at a cost of around £50 million, which opened in 1991 as the Sainsbury Wing.
Near the end of his life, Sainsbury entered into a civil partnership with his partner of 40 years, Stewart Grimshaw, a restaurateur and bookseller.
[5] Sir Nicholas Serota, the director of the latter institution, called the bequest "one of the most important gifts in the history of Tate".
