Keith Hart (born 1943 in Manchester, England) is International Director of the Human Economy Programme at the University of Pretoria and lives in Paris with his family. His main research has been on economic anthropology, Africa and the African diaspora. He has taught at numerous universities (including Yale University and the University of Chicago), most significantly at Cambridge where he was director of the African Studies Centre. He has contributed the concept of the informal economy to development studies and has published widely on economic anthropology. He is the author of The Memory Bank (aka Money in an Unequal World). One personal obsession has been the relationship between movement and identity in the transition from national to world society. But his written work focuses on the apparent impasse between the national limits of politics and the fact that the economy is now global.
