Peter [de] Thellusson was a Genevan businessman and banker who settled in London, and became a British subject in 1762. He amassed a fortune through commerce and, when he died in 1797, he owned more than 4,000 acres of land in England. His descendants built the new Brodsworth Hall in South Yorkshire, which is maintained by English Heritage.

Brodsworth Hall, near Brodsworth, 5 miles (8 km) north-west of Doncaster in South Yorkshire, is one of the most complete surviving examples of a Victorian country house in England. It is virtually unchanged since the 1860s. It was designed in the Italianate style by the obscure London architect, Philip Wilkinson, then 26 years old. He was commissioned by Charles Sabine Augustus Thellusson, who inherited the estate in 1859, but the original estate was constructed in 1791 for merchant and slave owner Peter Thellusson. It is a Grade I listed building.
