Sloane Square

neighborhood near Chelsea in London, named for Sir Hans Sloane (1660-1753), who purchased the manor of Chelsea in 1712 and whose celebrated collections contributed to the British Museum. Previous to development the place was known as Great Bloody Field ["Oxford Dictionary of London Place Names"]. The tree genus Sloanea was named for him. Sloane Ranger is attested from 1975, with a play on Lone Ranger.
