Walter Pitts taught himself Greek, Latin, and the foundations of modern logic in a Detroit public library, corrected Bertrand Russell's math by letter at age 12, and was taken in by a 45 year old scientist who treated him like a son. He helped found the architecture behind every neural network in existence at 19, and then a single lie destroyed every relationship he had, sending him into a 17 year drinking spiral that ended in a Cambridge boarding house in 1969. In this solo episode, I tell the full story of how Pitts' partnership with neurophysiologist Warren McCulloch produced the unbroken ancestor of the perceptron, backpropagation, and the transformer architecture behind today's large language models, and what happened when a fabricated accusation cut him off from every mentor he had. I lay out the specific conditions, free public libraries, mentors willing to take prodigies seriously, intellectual communities small enough to recognize raw talent, that made a mind like his possible, why those…
