Jean André Deluc or de Luc (1727-1817) was a Swiss geologist, meteorologist and natural philosopher, who also invented measuring instruments. He was born in Geneva and lived there until 1773, when he moved to England (bringing his daughter by his first wife) and was appointed reader to Queen Charlotte. He held this position for 44 years, but was given leave to make several scientific tours of Europe. He was admired for his research, and in 1773 he was made a Fellow of the Royal Society, and he was a correspondent of the French Academy of Sciences and a member of other learned societies. In 1785 he married Mary Cooper, a friend of Elizabeth Montagu, Elizabeth Carter and Fanny Burney. He died at Windsor in Berkshire, in 1817, at the age of ninety.
