William Kempster (1651–1717[1]) was an English master stonemason who worked with Sir Christopher Wren on St Paul's Cathedral.

Biography

William Kempster was the son of another stonemason, Christopher Kempster, from Burford in Oxfordshire, England, with a family quarry of Cotswold stone at Upton, near Burford. The Kempster family quarry supplied stone for Blenheim Palace, Oxford colleges, and Windsor Castle. In 1705, he was elected Master of the Masons' Company.[2][3]

Following his father, William Kempster was Christopher Wren's master mason with a team of masons during the rebuilding of St Paul's Cathedral in London. He carved the Dean's Door in 1690.[4] He was the main contractor at St Paul's from 1700 to 1717.[5][6] He maintained day books with payment records.[7][8] Initially, his father acted as a partner.[9] During 1706–8, Kempster had a team of 65 men working on the southwest tower and the vaults of St Paul's.[10] Kempster received £9,019 for his work on St Paul's.[11] He bought Portland stone and Purbeck stone for his work.[12]

The Geometric Staircase at St Paul's Cathedral, designed by Christopher Wren and built by William Kempster

Geometric Staircase

The Geometric Staircase, a helical cantilevered staircase with 88 stone stairs designed by Christopher Wren, was built by Kempster in the southwest tower of St Paul's and completed in 1710.[13] The steps are only embedded about 150mm into the walls since they are mainly supported by the steps below.[14] The staircase featured in the 1994 film The Madness of King George, the 2004 Harry Potter film, Harry Potter and the The Prisoner of Azkaban, and the 2009 Guy Ritchie film Sherlock Holmes.[15]

Other works

Kempster's other work included commissions at the following places:[16]

He also worked for the new coffee houses such as those at All Saints, Blackfriars, Ludgate, and St Paul's, as well as public houses including the Crown in Milk Street, the Dog Tavern at Garlick Hill, and the Haunch of Venison in Bow Lane.[19]

Kempster died while still working in 1717 at Garlick Hill, London.[1]
