Agnes Winifred Hoernlé née Tucker (6 December 1885–17 March 1960) was a South African anthropologist, widely recognized as the "mother of social anthropology in South Africa". Beyond her scientific work, she is remembered for her social activism and staunch disapproval of Apartheid based on white supremacy. Born in 1885 in the Cape Colony, as an infant she moved with her family to Johannesburg, where she completed her secondary education. After earning an undergraduate degree in 1906 from South African College, she studied abroad at Newnham College, Cambridge, Leipzig University, the University of Bonn, and the Sorbonne. Returning to South Africa in 1912, she undertook anthropological research among the Khoekhoe people, until she married in 1914.
