Peter Perez Burdett was an 18th-century cartographer, surveyor, artist, and draughtsman originally from Eastwood in Essex where he inherited a small estate and chose the name Perez from the birth surname of his mather, his maternal grandfather was the clergyman there. He would have been notable just for his many appearances in Joseph Wright's pictures but he was also involved with numerous projects including surveying the route for one of the major projects of the industrial revolution, the Leeds and Liverpool Canal, in 1769. He has been described as "if not in the centre at least in the penumbra of the Lunar Society of Birmingham". He spent the last years of his life in Karlsruhe, avoiding debtors, but still active in German society. His German daughter married a Count.

John Whitehurst FRS, born in Cheshire, England, was a clockmaker and scientist, and made significant early contributions to geology. He was an influential member of the Lunar Society.
