full_context: Document 1: Allison Davis: William Boyd Allison Davis (October 14, 1902 – November 21, 1983) was an American educator, anthropologist, writer, researcher, and scholar. He was considered one of the most promising black scholars of his generation, and he was the first African-American to hold a full faculty position at a major white university when he joined the staff of the University of Chicago in 1942, where he would spend the balance of his academic life. Among his students during his tenure at the University of Chicago were anthropologist St. Clair Drake and sociologist Nathan Hare. Davis, who has been honored with a commemorative postage stamp by the United States Postal Service, is best remembered for his pioneering anthropology research on southern race and class during the 1930s, his research on intelligence quotient in the 1940s and 1950s, and his support of "compensatory education" that contributed to the intellectual genesis of the federal Head Start Program.
Document 2: Alice Dewey: Alice Greeley Dewey (1928 – June 11, 2017) was an American anthropologist who studied Javanese society. She was a professor of anthropology at the University of Hawaiʻi at Mānoa from 1962 until her retirement in 2005. Among her doctoral students was Ann Dunham, the mother of President Barack Obama.
Document 3: Berkeley School of Latin Americanist Geography: The Berkeley School of Latin Americanist Geography was founded by the American geographer Carl O. Sauer. Sauer was a professor of geography at the University of California at Berkeley from 1923 until becoming professor emeritus in 1957 and was instrumental in the early development of the geography graduate program at Berkeley and the discipline of geography in the United States. Each generation of this research school has pursued new theoretical and methodological approaches, but their study of the peoples and places of Latin America and the Caribbean has remained the common denominator since the early 20th century. Carl O. Sauer himself did not develop a particular interest in Latin America before 1925, when Oskar Schmieder, a German geographer, disciple of Alfred Hettner, and expert in Latin American regional geography, arrived at Berkeley, coming from Córdoba, Argentina, to work as an Associate Professor. Obviously, his interest awoke during Schmieder's presence between 1925 and 1930. After Schmieder's departure in 1930, Carl O. Sauer began to offer seminars on the regional geography of Latin America.
Document 4: Alfred L. Kroeber: Alfred Louis Kroeber (June 11, 1876 – October 5, 1960) was an American cultural anthropologist. He received his Ph.D. under Franz Boas at Columbia University in 1901, the first doctorate in anthropology awarded by Columbia. He was also the first professor appointed to the Department of Anthropology at the University of California, Berkeley. He played an integral role in the early days of its Museum of Anthropology, where he served as Director from 1909 through 1947. Kroeber provided detailed information about Ishi, the last surviving member of the Yahi people, whom he studied over a period of years. He was the father of the acclaimed novelist, poet, and writer of short stories Ursula Kroeber Le Guin.
Document 5: John Pemberton (anthropologist): John Pemberton is an associate professor of anthropology at Columbia University. He received a Ph.D. from Cornell University after doing undergraduate and Masters' work at Wesleyan University and being associated with the music program at California Institute for the Arts.

Document 6: Mary LeCron Foster: Mary LeCron Foster (February 1, 1914 – December 9, 2001) was an American anthropological linguist, who spent most of her working life at the Department of Anthropology at the University of California, Berkeley. Foster carried out graduate work in anthropology under the direction of Ruth Benedict. The influence of Franz Boas, whom she also knew at Columbia, may be seen in Foster’s interests in symbolism and language origins. In addition to writing grammars of Sierra Popoluca and Purépecha, she published several articles purporting to reconstruct spoken Primordial Language (PL). PL, she maintained, was constructed out of speech sounds she dubbed ‘phememes’ that were at the same time roots, whose meaning was motivated by the shaping and movement of the vocal tract.
Document 7: Ishi: The Last of His Tribe: Ishi: The Last of His Tribe (1978) is a made-for-television biopic based on a book by Theodora Kroeber which relates the experiences of her husband Alfred L. Kroeber who made friends with Ishi, thought to be the last of his people, the Yahi tribe. Some think it is superior to the 1992 version of the same story "The Last of His Tribe", also a TV movie starring Jon Voight which was criticized for being too politically correct.
Document 8: Helen Codere: Helen Frances Codere (September 10, 1917 – June 5, 2009) was an American cultural anthropologist who received her BA from the University of Minnesota in 1939 and her PhD in anthropology from Columbia University where she studied with Ruth Benedict. She is best known for her work with the Kwakwaka'wakw people of coastal British Columbia, Canada, known formerly as the "Kwakiutl."
Document 9: Juana Maria: Juana Maria (died October 19, 1853), better known to history as the Lone Woman of San Nicolas Island (her Native American name is unknown), was a Native American woman who was the last surviving member of her tribe, the Nicoleño. She lived alone on San Nicolas Island off the coast of California from 1835 until her discovery in 1853. Scott O'Dell's award-winning children's novel "Island of the Blue Dolphins" (1960) was inspired by her story.
Document 10: The Last of His Tribe: The Last of His Tribe is a 1992 film starring Jon Voight as the anthropologist Alfred L. Kroeber who befriended Ishi, played by Graham Greene. Harry Hook directed the film. Ishi was thought to be the last of the Yahi people.

Although the exact time is never stated, it appears to be the mid- to late 1980s, as Mikhail Gorbachev's rise to power is mentioned. It was L'Amour's second-to-last published novel.
Document 12: Karl Kroeber: Karl Kroeber (1926–2009) was an American literary scholar, known for his writing on the English Romantics and American Indian literature.
