Mary Shepherd Slusser (1918-2017) was born in Canada and became a naturalized citizen of the United States in 1934. She was educated at the University of Michigan and Columbia University (Ph.D., 1950). The main focus of her graduate work was on archaeology. She also studied at the Institute of Fine Arts at New York University, and she took archaeology courses at Harvard University.
In 1951-1958, Slusser worked for the United States Department of State, responsible for anthropological reports concerning Latin America and then Southeast Asia. Following her husband's posting in Vietnam, she was stationed in Saigon beginning in 1954. While there, she produced basic ethnological studies of Vietnam and Laos.
In more recent years, Dr. Slusser accompanied her husband on other assignments. For five years she lived in Yugoslavia, then West Africa, and finally more than six years in Nepal. At the request of the Department of Anthropology of the National Museum of Natural History, on her arrival in Nepal in 1965 she made for them a small ethnographic collection from the Kathmandu Valley. Confronted by a dearth of basic works on Nepalese history and culture, she began research that would continue the next twenty years and lead to the publication of Nepal Mandala: A Cultural Study of Kethmandu Valley, 2 volumes, Princeton, New Jersey, Princeton University Press, 1982. Her bibliography also includes numerous academic papers and two more books devoted to Nepalese art and culture.
Returning to Washington, D.C. in 1971 she worked for the privately founded Museum of African Art (which later fused with the National Museum of African Art) and completed the writing of the above mentioned two-volume study. In 1989 she received a Post-Doctoral Fellowship from the Freer and Sackler Galleries of the Smithsonian Institution which led to a position as Senior Research Associate. Also in 1989 she was invited to Kathmandu to oversee the establishment of the Patan Museum devoted to the art of Nepal. She was a member of the Society of Women Geographers for which she recorded an oral history in 2012.
