Sir Hans Sloane, 1st Baronet, PRS (16 April 1660 – 11 January 1753) was an Irish born British physician, naturalist and collector, notable for bequeathing his collection to the nation, thus providing the foundation of the British Museum. His name was later used for streets and places such as Hans Place, Hans Crescent and Sloane Square in London, and also to Sir Hans Sloane Square in his birthplace, Killyleagh.
