Sir Christopher Wren (20 October 1632 – 25 February 1723) was one of the best known and highest acclaimed English architects in history, responsible for rebuilding 55 churches in the City of London after the Great Fire in 1666, including his masterpiece St Paul's Cathedral, completed in 1710.

Educated in Latin and Aristotelian physics at the University of Oxford, Wren was a notable astronomer, geometer, mathematician-physicist as well as an architect. He was a founder of the Royal Society (president 1680–82), and his scientific work was highly regarded by Sir Isaac Newton and Blaise Pascal.

Wren was born at East Knoyle in Wiltshire, the only surviving son of Christopher Wren DD (1589-1658), at that time the rector of East Knoyle and later Dean of Windsor. A previous child of Dr Wren, also named Christopher, was born on 22 November 1631, and had died the same day. John Aubrey’s confusion of the two persisted occasionally into late twentieth-century literature.
