Frank Rosenblatt
Frank Rosenblatt was a psychologist and early neural network researcher at Cornell. He developed the perceptron program at the Cornell Aeronautical Laboratory and later led the Cognitive Systems Research Program in Ithaca. A basic perceptron changes its input weights after an incorrect prediction, allowing examples to shape its behavior. His 1962 book Principles of Neurodynamics examined the theory of perceptrons, including more complex systems and open questions. Minsky and Papert later analyzed the limits of specific model classes. Rosenblatt died in 1971. His work remains part of the teaching of machine learning because it gives a clear example of a learning rule, a mathematical guarantee and the assumptions that guarantee requires.
