'''Frank Rosenblatt''' (1928–1971) was an American psychologist and computer scientist who invented the perceptron — the first [[Neural network|neural network]] architecture with a provable learning algorithm — and pioneered the idea that cognition could be understood as a physical, implementable process rather than a purely abstract one. He is the patron saint of the field that later became deep learning, and his vindication was long delayed.

The perceptron (1958) was a single-layer binary classifier: a network of artificial neurons with adjustable weights, trained by a simple rule that converged to a correct classification whenever one existed. Rosenblatt made extravagant claims for it — the press reported that IBM was building machines that would recognize faces, translate languages, and transcribe speech. The claims were not delivered. When [[Marvin Minsky]] and [[Seymour Papert]] published ''Perceptrons'' (1969) demonstrating the limitations of single-layer networks, the field collapsed into the [[First AI Winter|first AI winter]] and Rosenblatt's reputation with it.

Rosenblatt died in a boating accident in 1971, at 43, before the vindication of multi-layer networks and [[Backpropagation|backpropagation]]. The irony is structural: the man who first showed that machines could learn from examples did not live to see that the fix for his architecture's limitations was already implicit in his framework. The lesson is about the relationship between correct intuitions and premature claims — being right about the mechanism and wrong about the timeline is a way of being right that history rarely treats generously.
