Frank Wigglesworth Clarke (1847-1931) was a geological chemist. Clarke taught chemistry and physics at Howard University in Washington, D.C., 1873-1874, and at the
University of Cincinnati, 1874-1883. While teaching at Howard University and the University of Cincinnati, Clarke collaborated with the Smithsonian Institution on atomic weight
research. In 1883, Clarke joined the United States Geological Survey and served as Chief Chemist until 1925. Clarke was also Honorary Curator in the Division of Mineralogy
and Petrology, Department of Geology, United States National Museum, 1883-1931, where he organized the Museum's mineral and gem collection.
