Samuel Kirkland Lothrop (July 6, 1892 – January 10, 1965) was an American archaeologist and anthropologist who specialized in Central and South American Studies. His two-volume 1926 work Pottery of Costa Rica and Nicaragua is regarded as a pioneering study. Lothrop was a longtime research associate of Harvard's Peabody Museum of Archaeology and Ethnology and made many contributions based on fieldwork, laboratory analysis, and evaluations of private and public collections that focused on Central and South America. He is known for archaeological excavations in Argentina and Chile as well as investigations of the archaeological contexts for the stone spheres of Costa Rica. Lothrop is also known for his research on goldwork and other artifacts from Costa Rica, the Veraguas Province of Panama, and the Sacred Cenote at Chichen Itza, Mexico.[1]
