Timeline of artificial intelligence

This is a timeline of artificial intelligence, sometimes alternatively called synthetic intelligence.

Date	Development
Antiquity	Greek myths of Hephaestus and Pygmalion incorporated the idea of intelligent automata (such as Talos) and artificial beings (such as Galatea and Pandora).^[1]
Antiquity	Sacred mechanical statues built in Egypt and Greece were believed to be capable of wisdom and emotion. Hermes Trismegistus would write "they have sensus and spiritus ... by discovering the true nature of the gods, man has been able to reproduce it."^[2]
10th century BC	Yan Shi presented King Mu of Zhou with mechanical men which were capable of moving their bodies independently.^[3]
384 BC–322 BC	Aristotle described the syllogism, a method of formal, mechanical thought in the Organon.^[4]^[5]^[6] Aristotle also described means–ends analysis (an algorithm for planning) in Nicomachean Ethics, the same algorithm used by Newell and Simon's General Problem Solver (1959).^[7]
3rd century BC	Ctesibius invents a mechanical water clock with an alarm. This was the first example of a feedback mechanism.^{[citation needed]}
1st century	Hero of Alexandria created mechanical men and other automatons.^[8] He produced what may have been "the world's first practical programmable machine:"^[9] an automatic theatre.
260	Porphyry wrote Isagogê which categorized knowledge and logic, including a drawing of what would later be called a "semantic net".^[10]
~800	Jabir ibn Hayyan developed the Arabic alchemical theory of Takwin, the artificial creation of life in the laboratory, up to and including human life.^[11]
9th Century	The Banū Mūsā brothers created a programmable music automaton described in their Book of Ingenious Devices: a steam-driven flute controlled by a program represented by pins on a revolving cylinder.^[12] This was "perhaps the first machine with a stored program".^[9]
9th Century	al-Khwarizmi wrote textbooks with precise step-by-step methods for arithmetic and algebra, used in Islam, India and Europe until the 16th century. The word "algorithm" is derived from his name.^[13]
1206	Ismail al-Jazari created a programmable orchestra of mechanical human beings.^[14]
1275	Ramon Llull, Mallorcan theologian, invents the Ars Magna, a tool for combining concepts mechanically based on an Arabic astrological tool, the Zairja. Llull described his machines as mechanical entities that could combine basic truth and facts to produce advanced knowledge. The method would be developed further by Gottfried Wilhelm Leibniz in the 17th century.^[15]
~1500	Paracelsus claimed to have created an artificial man out of magnetism, sperm and alchemy.^[16]
~1580	Rabbi Judah Loew ben Bezalel of Prague is said to have invented the Golem, a clay man brought to life.^[17]

Date	Development
1620	Francis Bacon developed empirical theory of knowledge and introduced inductive logic in his work Novum Organum, a play on Aristotle's title Organon.^[18]^[19]^[6]
1623	Wilhelm Schickard drew a calculating clock on a letter to Kepler. This will be the first of five unsuccessful attempts at designing a direct entry calculating clock in the 17th century (including the designs of Tito Burattini, Samuel Morland and René Grillet).^[a]
1641	Thomas Hobbes published Leviathan and presented a mechanical, combinatorial theory of cognition. He wrote "...for reason is nothing but reckoning".^[20]^[21]
1642	Blaise Pascal invented a mechanical calculator,^[b] the first digital calculating machine.^[22]
1647	René Descartes proposed that bodies of animals are nothing more than complex machines (but that mental phenomena are of a different "substance").^[23]
1654	Blaise Pascal described how to find expected values in probability, in 1662 Antoine Arnauld published a formula to find the maximum expected value, and in 1663, Gerolamo Cardano's solution to the same problems is published 116 years after it was written. The theory of probability is further developed by Jacob Bernoulli and Pierre-Simon Laplace in the 18th century.^[24] Probability theory would become central to AI and machine learning from the 1990s onward.
1672	Gottfried Wilhelm Leibniz improved the earlier machines, making the Stepped Reckoner to do multiplication and division.^[25]
1676	Leibniz derived the chain rule.^[26] The rule is used by AI to train neural networks, for example the backpropagation algorithm uses the chain rule.^[9]
1679	Leibniz developed a universal calculus of reasoning (alphabet of human thought) by which arguments could be decided mechanically. It assigned a specific number to each and every object in the world, as a prelude to an algebraic solution to all possible problems.^[27]
1726	Jonathan Swift published Gulliver's Travels, which includes this description of the Engine, a machine on the island of Laputa: "a Project for improving speculative Knowledge by practical and mechanical Operations" by using this "Contrivance", "the most ignorant Person at a reasonable Charge, and with a little bodily Labour, may write Books in Philosophy, Poetry, Politicks, Law, Mathematicks, and Theology, with the least Assistance from Genius or study."^[28] The machine is a parody of Ars Magna, one of the inspirations of Gottfried Wilhelm Leibniz' mechanism.
1738	Daniel Bernoulli introduces the concept of "utility", a generalization of probability, the basis of economics and decision theory, and the mathematical foundation for the way AI represents the "goals" of intelligent agents.^[29]
1739	David Hume described induction, the logical method of learning generalities from examples.^[6]
1750	Julien Offray de La Mettrie published L'Homme Machine, which argued that human thought is strictly mechanical.^[30]
1763	Thomas Bayes's work An Essay Towards Solving a Problem in the Doctrine of Chances, published two years after his death, laid the foundations of Bayes' theorem and used in modern AI in Bayesian networks.^[24]
1769	Wolfgang von Kempelen built and toured with his chess-playing automaton, The Turk, which Kempelen claimed could defeat human players.^[31] The Turk was later shown to be a hoax, involving a human chess player.
1795-1805	The simplest kind of artificial neural network is the linear network. It has been known for over two centuries as the method of least squares or linear regression. It was used as a means of finding a good rough linear fit to a set of points by Adrien-Marie Legendre (1805)^[32] and Carl Friedrich Gauss (1795)^[33] for the prediction of planetary movement.^[9]^[34]
1800	Joseph Marie Jacquard created a programmable loom, based on earlier inventions by Basile Bouchon (1725), Jean-Baptiste Falcon (1728) and Jacques Vaucanson (1740).^[35] Replaceable punched cards controlled sequences of operations in the process of manufacturing textiles. This may have been the first industrial software for commercial enterprises.^[9]
1818	Mary Shelley published the story of Frankenstein; or the Modern Prometheus, a fictional consideration of the ethics of creating sentient beings.^[36]
1822–1859	Charles Babbage & Ada Lovelace worked on programmable mechanical calculating machines.^[37]
1837	The mathematician Bernard Bolzano made the first modern attempt to formalize semantics.^[38]
1854	George Boole set out to "investigate the fundamental laws of those operations of the mind by which reasoning is performed, to give expression to them in the symbolic language of a calculus", inventing Boolean algebra.^[39]
1863	Samuel Butler suggested that Darwinian evolution also applies to machines, and speculates that they will one day become conscious and eventually supplant humanity.^[40]

Date	Development
1910-1913	Bertrand Russell and Alfred North Whitehead published Principia Mathematica, which showed that all of elementary mathematics could be reduced to mechanical reasoning in formal logic.^[41]
1912-1914	Leonardo Torres Quevedo built an automaton for chess endgames, El Ajedrecista. He was called "the 20th century's first AI pioneer".^[9] In his Essays on Automatics (1914), Torres published speculation about thinking and automata and introduced the idea of floating-point arithmetic.^[42]^[43]
1923	Karel Čapek's play R.U.R. (Rossum's Universal Robots) opened in London. This is the first use of the word "robot" in English.^[44]
1920-1925	Wilhelm Lenz and Ernst Ising created and analyzed the Ising model (1925)^[45] which can be viewed as the first artificial recurrent neural network (RNN) consisting of neuron-like threshold elements.^[9] In 1972, Shun'ichi Amari made this architecture adaptive.^[46]^[9]
1920s and 1930s	Ludwig Wittgenstein's Tractatus Logico-Philosophicus (1921) inspires Rudolf Carnap and the logical positivists of the Vienna Circle to use formal logic as the foundation of philosophy. However, Wittgenstein's later work in the 1940s demonstrates that context free symbolic logic is incoherent without human interpretation.
1931	Kurt Gödel encoded mathematical statements and proofs as integers, and showed that there are true theorems that are unprovable by any consistent theorem-proving machine. Thus "he identified fundamental limits of algorithmic theorem proving, computing, and any type of computation-based AI,"^[9] laying foundations of theoretical computer science and AI theory.
1935	Alonzo Church extended Gödel's proof and showed that the decision problem of computer science does not have a general solution.^[47] He developed the Lambda calculus, which will eventually be fundamental to the theory of computer languages.
1936	Konrad Zuse filed his patent application for a program-controlled computer.^[48]
1937	Alan Turing published "On Computable Numbers",^[49] which laid the foundations of the modern theory of computation by introducing the Turing machine, a physical interpretation of "computability". He used it to confirm Gödel by proving that the halting problem is undecidable.
1940	Edward Condon displayed Nimatron, a digital machine that played Nim perfectly.
1941	Konrad Zuse built the first working program-controlled general-purpose computer.^[50]

1945	Game theory which would prove invaluable in the progress of AI was introduced with the 1944 paper "Theory of Games and Economic Behavior" by mathematician John von Neumann and economist Oskar Morgenstern.
1945	Vannevar Bush published "As We May Think" (The Atlantic Monthly, July 1945) a prescient vision of the future in which computers assist humans in many activities.
1948	Alan Turing produces "Intelligent Machinery" report, regarded as the first manifesto of Artificial Intelligence. It introduces many concepts including the logic-based approach to problem solving, that intellectual activity consists mainly of various kinds of search, and a discussion of machine learning in which he anticipates the Connectionism AI approach.^[52]
1948	John von Neumann (quoted by Edwin Thompson Jaynes) in response to a comment at a lecture that it was impossible for a machine (at least ones created by humans) to think: "You insist that there is something a machine cannot do. If you will tell me precisely what it is that a machine cannot do, then I can always make a machine which will do just that!". Von Neumann was presumably alluding to the Church–Turing thesis which states that any effective procedure can be simulated by a (generalized) computer.
1949	Donald O. Hebb develops Hebbian theory, a possible algorithm for learning in neural networks.^[53]

Date	Development
1950	Alan Turing published "Computing Machinery and Intelligence", which proposes the Turing test as a measure of machine intelligence and answered all of the most common objections to the proposal "machines can think".^[54]

	Isaac Asimov published his Three Laws of Robotics.^[56]
1951	The first working AI programs were written in 1951 to run on the Ferranti Mark 1 machine of the University of Manchester: A checkers-playing program written by Christopher Strachey and a chess-playing program written by Dietrich Prinz.^[53]
1952–1962	Arthur Samuel (IBM) wrote the first game-playing program, for checkers (draughts), to achieve sufficient skill to challenge a respectable amateur.^[57] His first checkers-playing program was written in 1952, and in 1955 he created a version that learned to play.^[58]^[59]
1956	The Dartmouth College summer AI conference is organized by John McCarthy, Marvin Minsky, Nathan Rochester of IBM and Claude Shannon. McCarthy coins the term artificial intelligence for the conference.^[60]^[61]
1956	The first demonstration of the Logic Theorist (LT) written by Allen Newell, Cliff Shaw and Herbert A. Simon (Carnegie Institute of Technology, now Carnegie Mellon University or CMU). This is often called the first AI program, though Samuel's checkers program also has a strong claim. This program has been described as the first deliberately engineered to perform automated reasoning, and would eventually prove 38 of the first 52 theorems in Russell and Whitehead's Principia Mathematica, and find new and more elegant proofs for some.^[62] Simon said that they had "solved the venerable mind–body problem, explaining how a system composed of matter can have the properties of mind".^[63]
1958	John McCarthy (Massachusetts Institute of Technology or MIT) invented the Lisp programming language.^[58]
	Herbert Gelernter and Nathan Rochester (IBM) described a theorem prover in geometry.^[58] It exploited a semantic model of the domain in the form of diagrams of "typical" cases.^{[citation needed]}
	Teddington Conference on the Mechanization of Thought Processes was held in the UK and among the papers presented were John McCarthy's "Programs with Common Sense" (which proposed the Advice taker application as a primary research goal)^[58] Oliver Selfridge's "Pandemonium", and Marvin Minsky's "Some Methods of Heuristic Programming and Artificial Intelligence".

1960	"Man-Computer Symbiosis" by J.C.R. Licklider.
1961	James Slagle (PhD dissertation, MIT) wrote (in Lisp) the first symbolic integration program, SAINT, which solved calculus problems at the college freshman level.
	In Minds, Machines and Gödel, John Lucas^[64] denied the possibility of machine intelligence on logical or philosophical grounds. He referred to Kurt Gödel's result of 1931: sufficiently powerful formal systems are either inconsistent or allow for formulating true theorems unprovable by any theorem-proving AI deriving all provable theorems from the axioms. Since humans are able to "see" the truth of such theorems, machines were deemed inferior.
	Unimation's industrial robot Unimate worked on a General Motors automobile assembly line.

1964	Danny Bobrow's dissertation at MIT (technical report #1 from MIT's AI group, Project MAC), shows that computers can understand natural language well enough to solve algebra word problems correctly.
1964	Bertram Raphael's MIT dissertation on the SIR program demonstrates the power of a logical representation of knowledge for question-answering systems.
1965	Alexey Ivakhnenko and Valentin Lapa developed the first deep learning algorithm for multilayer perceptrons in Soviet Union.^[69]^[70]^[9]
	Lotfi A. Zadeh at U.C. Berkeley publishes his first paper introducing fuzzy logic, "Fuzzy Sets" (Information and Control 8: 338–353).
	J. Alan Robinson invented a mechanical proof procedure, the Resolution Method, which allowed programs to work efficiently with formal logic as a representation language.
	Joseph Weizenbaum (MIT) built ELIZA, an interactive program that carries on a dialogue in English language on any topic. It was a popular toy at AI centers on the ARPANET when a version that "simulated" the dialogue of a psychotherapist was programmed.
	Edward Feigenbaum initiated Dendral, a ten-year effort to develop software to deduce the molecular structure of organic compounds using scientific instrument data. It was the first expert system.
1966	Ross Quillian (PhD dissertation, Carnegie Inst. of Technology, now CMU) demonstrated semantic nets.
	Machine Intelligence^[71] workshop at Edinburgh – the first of an influential annual series organized by Donald Michie and others.

	Dendral program (Edward Feigenbaum, Joshua Lederberg, Bruce Buchanan, Georgia Sutherland at Stanford University) demonstrated to interpret mass spectra on organic chemical compounds. First successful knowledge-based program for scientific reasoning.
1967	Shun'ichi Amari was the first to use stochastic gradient descent for deep learning in multilayer perceptrons.^[72] In computer experiments conducted by his student Saito, a five layer MLP with two modifiable layers learned useful internal representations to classify non-linearily separable pattern classes.^[9]
1968	Joel Moses (PhD work at MIT) demonstrated the power of symbolic reasoning for integration problems in the Macsyma program. First successful knowledge-based program in mathematics.
	Richard Greenblatt (programmer) at MIT built a knowledge-based chess-playing program, Mac Hack, that was good enough to achieve a class-C rating in tournament play.
	Wallace and Boulton's program, Snob (Comp.J. 11(2) 1968), for unsupervised classification (clustering) uses the Bayesian minimum message length criterion, a mathematical realisation of Occam's razor.
1969	Stanford Research Institute (SRI): Shakey the robot, demonstrated combining animal locomotion, perception and problem solving.
	Roger Schank (Stanford) defined conceptual dependency model for natural language understanding. Later developed (in PhD dissertations at Yale University) for use in story understanding by Robert Wilensky and Wendy Lehnert, and for use in understanding memory by Janet Kolodner.
	Yorick Wilks (Stanford) developed the semantic coherence view of language called Preference Semantics, embodied in the first semantics-driven machine translation program, and the basis of many PhD dissertations since such as Bran Boguraev and David Carter at Cambridge.
	First International Joint Conference on Artificial Intelligence (IJCAI) held at Stanford.
	Marvin Minsky and Seymour Papert publish Perceptrons, demonstrating previously unrecognized limits of this feed-forward two-layered structure. This book is considered by some to mark the beginning of the AI winter of the 1970s, a failure of confidence and funding for AI. However, by the time the book came out, methods for training multilayer perceptrons by deep learning were already known (Alexey Ivakhnenko and Valentin Lapa, 1965; Shun'ichi Amari, 1967).^[9] Significant progress in the field continued (see below).
	McCarthy and Hayes started the discussion about the frame problem with their essay, "Some Philosophical Problems from the Standpoint of Artificial Intelligence".
