A pair of Queen Mary University of London psychologists are reminding modern scholars of the work conducted by an accomplished pioneer of comparative animal intelligence study: Charles Henry Turner, a Black biologist who conducted animal cognition studies in the late 1800s and early 1900s. Hiruni Samadi Galpayage Dona and Lars Chittka have published a Perspective piece in the journal Science outlining the work done by Turner and the obstacles that stood in the way of his research.
