This is a story about boundaries – physical, biological, ethical. It evolved from a conversation with the late Dr. Alfred Prince, a hepatitis researcher, about the use of chimpanzees in medical research and expanded into a larger discussion about ethics. Prince left New York University’s Laboratory for Experimental Medicine and Surgery in Primates (LEMSIP) in the 1970s to establish New York Blood Center’s chimpanzee research colony in Liberia. The story weaves various threads and makes connections between logging, the Liberian Civil War, and vivisection. Chimpanzees are slowly being phased out of research in the United States, and the New York Blood Center has ceased testing in Liberia, but questions remain about the fate of laboratory chimpanzees.
