Ashley Montagu (1905-1999), physical anthropologist, was a prominent figure in American intellectual life. British by birth, educated at University College London and the London School of Economics, then Columbia University in New York City, Montagu was a persistent advocate for gender and racial equality. He was a tireless activist for human understanding and child welfare in particular. Departing from academe in 1955, a victim of McCarthyite hysteria, he was a remarkably prolific writer and speaker, eventually publishing more than 50 books, over 40 of them after he left the academy. Montagu continued to lobby passionately against the primacy of race in discussions of intellect and skill, and undertook works in a wide variety of fields, from evolution to parenting. Some of his most significant works include Man's Most Dangerous Myth: The Fallacy of Race (1942), the UNESCO Statement on Race (1951), Man and Aggression (1968) and his novel The Elephant Man (1971), which became the basis for an award winning play and movie. Ashley Montagu's contributions to the spread of scientific knowledge and human understanding make him one of the most important intellectuals of the 20th century.

Dell Hymes' doctoral research on Kathlamet Chinook (Indiana University, 1955) grew into a lifelong interest in the relationship between ethnography and linguistics. Following academic appointments at Harvard University (1955-1960) and the University of California, Berkley (1960-1965), Hymes joined the Department of Anthropology at the University of Pennsylvania in 1965. During twenty-two years tenure at Penn he was a professor of folklore, linguistics, sociology and education. In 1975, he was promoted to Dean of the Graduate School of Education (1975-1987). A principal proponent of the emergent field of sociolinguistics, his most influential works include Reinventing Anthropology and Language in Culture and Society. The Hymes papers cover all aspects of Dell Hymes' professional life. Subcollection I is concentrated on his years at the University of Pennsylvania, his presidencies of the American Association of Anthropology and the Linguistic Society of America, and his editorship of the journal Language in Society. Subcollection II is broader, focusing much more on published and unpublished linguistic work on dozens of languages, mostly of North America. Of particular interest is his rich correspondence with colleagues and students on linguistic issues. The papers reflect Hymes' interests in the history of linguistics and anthropology, Native American languages (especially oral literatures), and his comparative ethnographies of communication.
