Amanda Gefter described the fascinating life of Walter Pitts, who was bullied as a child in Detroit and took refuge in the local library where he taught himself Greek, Latin, logic, and mathematics. He ran away from home at age 15, became a pioneer in neuroscience and cybernetics at MIT, and later became a withdrawn alcoholic. Pitts worked with Warren McCulloch, who was born at the other end of the economic spectrum in a family of privilege. "McCulloch and Pitts were destined to live, work, and die together," Gefter writes. "Along the way, they would create the first mechanistic theory of the mind, the first computational approach to neuroscience, the logical design of modern computers, and the pillars of artificial intelligence." The story is about more than a research collaboration, she writes: "It is also about the bonds of friendship, the fragility of the mind, and the limits of logic's ability to redeem a messy and imperfect world." Gefter said she felt "incredibly lucky to tell this extraordinary story."
