Sir Christopher  Wren was an English scientist and mathematician and one of Britain's most distinguished architects, best known for the design of many London churches, including St Paul's Cathedral.

Christopher Wren was born on 20 October 1632 in East Knoyle, Wiltshire, where his father was rector. His father later moved to Windsor and Wren was educated at Westminster School and then Oxford University.

 He showed an early talent for mathematics and enjoyed inventing things, including an instrument for writing in the dark and a pneumatic machine.

 Wren's interest in architecture developed from his study of physics and engineering. In 1664 and 1665, Wren was commissioned to design the Sheldonian Theatre in Oxford and a chapel for Pembroke College, Cambridge and from then on, architecture was his main focus.

 In 1665, Wren visited Paris, where he was strongly influenced by French and Italian baroque styles.

In 1666, the Great Fire of London destroyed much of the medieval city, providing a huge opportunity for Wren. He produced ambitious plans for rebuilding the whole area but they were rejected, partly because property owners insisted on keeping the sites of their destroyed buildings. Wren did design 51 new city churches, as well as the new St Paul's Cathedral.

 In 1669, he was appointed surveyor of the royal works which effectively gave him control of all government building in the country. He was knighted in 1673.

In 1675, Wren was commissioned to design the Royal Observatory at Greenwich. In 1682, he received another royal commission, to design a hospital in Chelsea for retired soldiers, and in 1696 a hospital for sailors in Greenwich. Other buildings include Trinity College Library in Cambridge (1677 - 1692), and the facade of Hampton Court Palace. Wren often worked with the same team of craftsmen, including master plasterer John Groves and wood carver Grinling Gibbons

Wren died on 25 February 1723. His gravestone in St Paul's Cathedral features the Latin inscription which translates as:

'If you seek his memorial, look about you.'
