Birth of AI
1956-1970s · Dartmouth Conference & First Wave
In the summer of 1956, in a small town in New Hampshire, USA, a group of young scientists gathered to discuss what then seemed like science fiction—giving machines human intelligence. This was the famous Dartmouth Conference, where the term "Artificial Intelligence" was first formally proposed. The following decade saw scientists filled with optimism about neural networks, reasoning systems, and robotics, ushering in AI's first golden age. While many dreams of this era were not immediately realized, the work laid an important foundation for AI's later development. This era's AI research focused on three main directions: symbolism (logic and rules-based), connectionism (neural networks), and behaviorism (perception-action loops). These three directions have alternately dominated the history of AI development.
Key Milestones
Dartmouth Conference
In August 1956, at a two-month workshop at Dartmouth College, the term "Artificial Intelligence" was first formally proposed. The conference organizers included John McCarthy, Marvin Minsky, Claude Shannon, and Nathaniel Rochester.
John McCarthy (1927-2011)
Logic Theorist
Allen Newell and Herbert Simon developed the "Logic Theorist", the first practical AI program. This program could prove theorems from Principia Mathematica and is considered the first AI program. Newell and Simon received the Turing Award in 1975.
Allen Newell & Herbert Simon
Perceptron
Frank Rosenblatt proposed the Perceptron model, the first truly artificial neural network model. The Perceptron is a simple linear binary classifier that learns to classify input data by adjusting weights.
Frank Rosenblatt (1928-1971)
Lisp Language
John McCarthy developed Lisp at MIT, the first high-level programming language specifically designed for AI research. Lisp's flexibility and powerful symbolic processing made it the language of choice for AI research.
John McCarthy
General Problem Solver
Newell and Simon developed the General Problem Solver (GPS), the first AI program that attempted to simulate human problem-solving. GPS decomposed problem-solving into goal decomposition and sub-goal search.

Perceptron Convergence Theorem
Frank Rosenblatt proved the convergence property of the perceptron learning algorithm, showing that if data is linearly separable, the perceptron will definitely converge.

First Industrial Robot
Unimate became the first robot to work in an industrial setting. Installed on a General Motors assembly line, Unimate removed hot metal parts from die-casting machines and welded them in place.

MIT AI Lab
Marvin Minsky founded the MIT AI Lab, the world's second AI research institution (the first was Stanford AI Lab). MIT AI Lab became an important center for AI research.
Marvin Minsky
ELIZA
Joseph Weizenbaum created ELIZA at MIT, the first chatbot. ELIZA simulated a psychotherapist's conversation through pattern matching, sparking deep reflection on human-computer interaction.
Joseph Weizenbaum (1923-2008)
First Computer Vision System
Larry Roberts developed the first computer vision system capable of recognizing simple geometric shapes at MIT. The system could extract edges and basic shapes from images.

Shakey the Robot
SRI International developed Shakey, the first autonomous mobile robot that could perceive its environment, plan paths, and execute tasks. Shakey combined computer vision, NLP, and planning algorithms.
SRI International
Frame Theory
Marvin Minsky published the "Frame Paper", proposing Frame theory for knowledge representation. This theory influenced later object-oriented programming and knowledge representation methods.

Key Figures
John McCarthy
Father of AI
McCarthy was one of the founding figures of AI. He coined the term "Artificial Intelligence" and developed the Lisp programming language. He received the Turing Award in 1971 and is known as the "Father of AI". McCarthy also proposed the concept of "time-sharing".
Marvin Minsky
AI Architecture Pioneer
Minsky was a co-founder of MIT's AI Lab. He made important contributions to neural networks, common-sense reasoning, and frame theory. He received the Turing Award in 1979.
Allen Newell & Herbert Simon
Cognitive Scientists
Newell and Simon co-developed the Logic Theorist and the General Problem Solver, combining computer science and cognitive psychology. Simon received the Nobel Prize in Economics in 1978 and the Turing Award in 1994.
Frank Rosenblatt
Neural Network Pioneer
Rosenblatt was the inventor of the Perceptron. Although neural network research experienced a winter, his work laid the foundation for today's deep learning.
Joseph Weizenbaum
HCI Pioneer
Weizenbaum created ELIZA. Although technically simple, it sparked profound philosophical discussions about human-computer interaction and machine intelligence. Weizenbaum later became an early advocate of AI ethics.
