Isaac Newton, 25 December 1642 - 20 March 1727, scientist, mathematician, philosopher.
Isaac Newton was born at Woolsthorpe in Lincolnshire. He entered Trinity College, Cambridge in 1660. He propounded the laws of motion, universal gravitation, optics and the basis of differential calculus. He was Master of the Mint from 1699 - 1727, President of the Royal Society from 1703 - 26 and was knighted in 1705.
He is supposed to have lived in Leicester Square, but actually lived nearby at 35 St. Martin's Street, and is buried in Westminster Abbey.
The bust is by William Calder Marshall (1874).
All four of the Leicester Square busts were removed in the 2010-12 redesign, and we don't know where they went.
