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. Early life Lothrop was a descendant of his namesake, prominent Unitarian minister Samuel Kirkland Lothrop. He was born in Milton, Massachusetts on July 6, 1892 to William and Alice Lothrop.

Education Lothrop began his education at Groton School, a private boarding school in Massachusetts. He entered Harvard University in 1911, where he completed his undergraduate studies in 1915. In 1914 he married Rachel Warren, daughter of Fiske and Gretchen Osgood Warren. After completing his undergraduate studies he began graduate school at Harvard, focusing on anthropology and archaeology. He traveled extensively throughout Central America as a research associate of the Peabody Museum, excavating various areas and studying collections. His travels and excavations were interrupted by the eruption of World War I, where he served in military intelligence. After the war, he returned to his graduate work, eventually earning his Ph.D. with a doctoral dissertation, a version of which was published in 1926 as Pottery of Costa Rica and Nicaragua. Military career Lothrop was engaged in espionage for the U.S. prior to and during World War I and for the Office of Strategic Services prior to and during World War II.
