Claude François Geoffroy (1729 – 18 June 1753) was a French chemist. He discovered the chemical element bismuth in 1753. Before this time, bismuth-containing minerals were frequently identified as either lead or tin ores. His observations on the matter were published in the Mémoires de l’académie française in 1753.[1][2]

He became a master apothecary in 1748, and in 1752 he was admitted to the Académie des sciences as a supernumerary adjoint chemist. He died on 18 June 1753, (age 23 or 24).[3]

He is known as Claude Geoffroy the Younger to distinguish him from his father Claude Joseph Geoffroy (1685–1752), also a French chemist and apothecary, member of the Académie des sciences.
