Glenn Albert Black was an American archaeologist, author, and part-time university lecturer who was among the first professional archaeologists to study prehistoric sites in Indiana continuously. Black, a pioneer and innovator in developing archaeology field research techniques, is best known for his excavation of Angel Mounds, a Mississippian community near present-day Evansville, Indiana, that he brought to national attention. Angel Mounds was designated a National Historic Landmark in 1964. Black was largely self-taught and began serious work on archaeological sites in Indiana in the 1930s, before there were many training opportunities in archaeology in the United States. He is considered to have been the first full-time professional archaeologist focusing on Indiana's ancient history, and the only professional archaeologist in the state until the 1960s. During his thirty-five-year career as an archaeologist in Indiana, Black also worked as a part-time lecturer at Indiana University Bloomington from 1944 to 1960 and conducted a field school at the Angel site during the summer months.

Angel Mounds State Historic Site, an expression of the Mississippian culture, is an archaeological site managed by the Indiana State Museum and Historic Sites that includes more than 600 acres of land about 8 miles (13 km) southeast of present-day Evansville, in Vanderburgh and Warrick counties in Indiana. The large residential and agricultural community was constructed and inhabited from AD 1100 to AD 1450, and served as the political, cultural, and economic center of the Angel chiefdom. It extended within 120 miles (190 km) of the Ohio River valley to the Green River in present-day Kentucky. The town had as many as 1,000 inhabitants inside the walls at its peak, and included a complex of thirteen earthen mounds, hundreds of home sites, a palisade (stockade), and other structures.
