Marjorie Shostak (May 11, 1945 – October 6, 1996) was an American anthropologist. Though she never received a formal degree in anthropology, she conducted extensive fieldwork among the !Kung San people of the Kalahari desert in south-western Africa and was widely known for her descriptions of the lives of women in this hunter-gatherer society.
Shostak was raised in Brooklyn, New York. She received her B.A. in literature from Brooklyn College, where she was a supporter of the women's equal rights movement, and met her future husband, Melvin Konner.
In 1969-1971, Shostak and Konner lived among the !Kung San in the Dobe region of southwest Africa, on the border between Botswana and South Africa. There they learned the !Kung language and conducted anthropological fieldwork. While her husband looked at medical issues like nutrition and fertility, Shostak examined the role of women in the !Kung San society, becoming close with one woman in particular, known by the pseudonym "Nisa". Shostak's book on the subject, Nisa: The Life and Words of a !Kung Woman, was first published by Harvard University Press in 1981, and is now a standard work in anthropology. It weaves together the different voices of Shostak and Nisa, alternating between anthropological observation and the life story of a "primitive" woman told in her own words. In the book Shostak argues that !Kung San women had higher status and autonomy than women in Western cultures because of their food contributions.
During the 1980s, Shostak and Konner also wrote a popular book and a number of articles advocating a "Paleolithic diet". Though there have been some disputes over the full benefits of such a diet and how it should be implemented, the basic idea is that many illnesses found in agricultural and industrialized societies result at least in part from diets that differ significantly from those that human beings evolved to eat.
