James V. McConnell

Born on October 26, 1925, and dying on April 9, 1990, he was an American biologist and animal psychologist whose name is most closely linked with research on learning and memory transfer in planarians, or flatworms. Those experiments made him a widely recognized and sometimes controversial figure in psychology.

Much of his academic career was spent at the University of Michigan, where he taught psychology and built a reputation as a lively, accessible science communicator. Alongside his research, he wrote for broader audiences and helped make complex ideas in psychology feel approachable.

What makes him memorable today is the mix of scientific ambition and public curiosity in his work. Even when later researchers debated his conclusions, his experiments and writing left a real mark on how people talked about memory, learning, and the possibilities of behavioral science.
