Jan Vansina

Jan Vansina (14 September 1929 – 8 February 2017) was a Belgian historian and anthropologist regarded as an authority on the history of Central Africa, especially of what is now the Democratic Republic of the Congo, Rwanda, and Burundi. He was a major innovator in the historical methodology of oral tradition. As a professor at the University of Wisconsin–Madison, he taught several generations of students and, according to a biographer, "set the pace in African historical studies from the 1950s into the 1990s."
