This article examines how openly sharing data online can continue the dehumanizing work of 19th century “collectors” who stole the bodies of colonized peoples. It addresses the ongoing controversies at the University of Pennsylvania Museum of Archaeology and Anthropology (“Penn Museum“), regarding the interlinked weaponization of over one thousand crania used by racial scientist Samuel George Morton, and the remains of two Black children murdered by the police in the 1985 MOVE bombing, and asks, how can descendant communities regain their kin and take control of the data the museum has extracted from them? And how can scholars and other heritage workers within colonial institutions support them?
