Name:
Named in honor of Jean-Etienne Guettard (1715-1786), French geologist, botanist and natural historian. He is credited with the creation of the first mineralogical-geological map known (western Europe) in 1746, Carte minéralogique du Canada et de la Louisiane (Eastern Canada and USA) in 1752, followed by the Atlas minéralogique de la France (with Lavoisier) in 1767, and the Carte minéralogique de la France in 1784. Guettard was a member of the Académie des Sciences from 1743, and is the author of La minéralogie du Dauphiné (1782).
