About Robert Clayton
Lived 1629 – 1707 (aged 77–78). Robert Clayton was a banker, politician, slave trader and merchant.
Sir Robert Clayton (1629–1707) was an English merchant banker, politician and Lord Mayor of London.
Life Robert Clayton was born in Northamptonshire, England. He became an apprentice to his uncle, a London scrivener, where he met a fellow apprentice, Alderman John Morris. They became successful businessmen and established the bank, Clayton & Morris Co.
Clayton entered politics, representing London and Bletchingley alternately as a Whig between 1679 and his death in 1707. He was knighted in 1671. Clayton made a considerable fortune. In 1697 he lent the king £30,000 to pay for the army. In the mid-1650s Clayton purchased Brownsea Island and its castle.
He was president of the St Thomas' Hospital in London which was then located in the Borough. He employed Thomas Cartwright to rebuild the hospital and St Thomas Church nearby.
Robert Clayton was a member of the Scriveners and Drapers Company, an Alderman of Cheap Ward in the City of London (1670–1683), a Sheriff in 1671, Lord Mayor of London (1679–1680), a member of parliament for the City of London or Bletchingley for most of the years 1679 to 1707, Colonel of the Orange Regiment, London Trained Bands (various times, 1680–1702), President of the Honourable Artillery Company (1690–1703), Commissioner of the Customs (1689–1697), an Assistant to the Royal African Company (1672–1681) and a director of the Bank of England (1702–1707).
In the 1690s, Clayton was the head of the earliest known Freemason lodge entirely made-up of non-working masons in London.
Links to slavery As a member of the Court of Assistants to the Royal African Company, Clayton was essentially on the board of directors. The Royal African Company shipped more African slaves to the Americas than any other institution in the history of the Atlantic slave trade. Clayton married Martha Trott, who was the daughter of a Bermuda merchant, and also acted as Factor in Bermuda.
Legacy The tomb of Sir Robert and Lady Clayton is in St Mary's church, Bletchingley.
A statue of Clayton stood at the North Entrance to Ward Block of North Wing at St Thomas' Hospital and is Grade I listed. On 11 June 2020, a joint statement from the Guy's and St Thomas' NHS Foundation Trust announced that Clayton's statue, together with that of Thomas Guy, would be removed from public view. Both statues have subsequently been put back on display.
