# Claude François Geoffroy

> Claude François Geoffroy was a French chemist. In 1753 he proved the chemical element bismuth to be distinct from lead, becoming the official discoverer of the element. Before this time, bismuth-containing minerals were frequently misidentified as either lead, tin, or antimony ores. His observations on the matter were published in the Mémoires de l’académie française in 1753.
