Linton Satterthwaite Jr. (1897–1978) was a Maya archaeologist and epigrapher and is primarily associated with the University Museum at the University of Pennsylvania. He is well known for his works at Caracol, Piedras Negras, Cahal Pech and Benque Viejo (Xunantunich). Early life and training Satterthwaite was born in Trenton, New Jersey and had a public school education in the area. After graduating from Trenton High School, Satterthwaite joined the military and served as a cadet and flying officer for the Royal Navy Air Force during World War I. Afterwards, he decided to attend Yale University for his B.A. and worked as a reporter from 1929 to 1931. He participated as an archaeological assistant in excavations in Texas, West Virginia, and Guatemala. Satterthwaite was awarded his Ph.D. in Anthropology in 1943. Piedras Negras In 1932, Linton Satterthwaite was named assistant director for the excavations at Piedras Negras. In 1933, J. Alden Mason left his position as field director at Piedras Negras, and the title was then given to Satterthwaite until 1939. The focus of the expeditions at Piedras Negras was to answer archaeological questions such as establishing building sequences, stratigraphy, and uncovering architectural remains. This was a stark difference from that of Mason, who focused on monumental sculptures. Acting as director, Satterthwaite was able to excavate eleven temples, seventeen palaces, two ballcourts and multiple sweatbaths. During his time at Piedras Negras, Satterthwaite was very well known for using a diligent and systematic approach in identifying building function. Satterthwaite also mapped many small buildings, setting a standard used by Mayanists to come (Houston et al. 1998). Because of Satterthwaite’s legal background, he was also able to effectively create detailed isometrics that conveyed the substance of excavations and define terms and labels. Although many publications on Piedras Negras came out during his time there, Satterthwaite was still never able to finish all of the reports that he intended to. One publication that was completed the book Piedras Negras Archaeology, 1931-1939. Among the archaeologists who worked with Satterthwaite at Piedras Negras was Mary Butler Lewis, a leading expert on Mesoamerican ceramics, and the first woman to receive a PhD in Anthropology from Penn. Caracol, Belize Initial discovery and research of Caracol, Belize occurred in 1938, when Rosa Mai discovered the ancient ruins and A.H. Anderson did initial research, discovering 8 pieces of stelae in the process. From 1950 to 1958, Linton Satterthwaite directed three
