William S. Willis Jr. (1921-1983), anthropologist and ethnohistorian, contributed significantly to the understanding of the dynamics of inter-cultural exchange in a multicultural context. After receiving his doctorate from Columbia University, he was hired as the first African American professor of Anthropology at Southern Methodist University. Upon resigning in protest from SMU in 1972, he returned to teach at Columbia University until 1975. His final years were spent studying Boasian anthropology. The collection includes correspondence, lecture notes, manuscripts of Willis' writings, and working notes. Of note, are the memos concerning his leaving Southern Methodist University and his extensive research notes on Franz Boas' views on race relations in America.
