Sir William Hamo Thornycroft was an English sculptor, responsible for some of London's best-known statues, including the statue of Oliver Cromwell outside the Palace of Westminster. He was a keen student of classical sculpture and was one of the youngest artists to be elected to the Royal Academy, in 1882, the same year the bronze cast of Teucer was purchased for the British nation under the auspices of the Chantrey Bequest.

A statue of Oliver Cromwell stands outside the House of Commons of the United Kingdom in Westminster, London. Oliver Cromwell was Lord Protector of the Commonwealth of England, Scotland and Ireland between 1653 and 1658. Directly opposite the statue, in the wall of St Margaret's Church, on the other side of the road, is a bust of Charles I, which is often unnoticed.
