What Happened

Frank Rosenblatt built the Mark I Perceptron, the first hardware implementation of an artificial neural network. It could learn to classify simple visual patterns. The New York Times reported it as an 'Electronic Brain' that the Navy expected would 'be able to walk, talk, see, write, reproduce itself and be conscious of its existence.'

Why It Mattered

First practical neural network. The media hype and subsequent backlash (Minsky & Papert's 1969 critique) set a pattern that AI would repeat for decades: overpromise, underdeliver, winter.

The Dartmouth Conference

A two-month workshop at Dartmouth College where the term 'Artificial Intelligence' was officially coined. The proposal stated: 'Every aspect of learning or any other feature of intelligence can in principle be so precisely described that a machine can be made to simulate it.' This gathering brought together the founders of the field.

First Mathematical Model of Neural Networks

McCulloch and Pitts published 'A Logical Calculus of Ideas Immanent in Nervous Activity,' creating the first mathematical model of an artificial neuron. They showed that simple binary neurons connected in networks could, in principle, compute any function computable by a Turing machine.

Logic Theorist: The First AI Program

Newell and Simon created the Logic Theorist, often called the first AI program. It could prove mathematical theorems from Whitehead and Russell's Principia Mathematica — and even found a more elegant proof than the original for one theorem. It was debuted at the Dartmouth Conference.

ELIZA: The First Chatbot

Joseph Weizenbaum created ELIZA, a program that simulated a Rogerian psychotherapist using simple pattern matching. Despite being purely rule-based with no understanding, users became emotionally attached to it and insisted it truly understood them — a phenomenon Weizenbaum found deeply disturbing.

SHRDLU: Natural Language Understanding

Terry Winograd created SHRDLU, a program that could understand and respond to English commands about a simulated 'blocks world.' Users could ask it to move objects, answer questions about their arrangement, and even understand pronouns and context within its limited domain.
