INTRODUCTION

The intellectual roots of AI, and the concept of intelligent machines, may be found in Greek mythology. Intelligent artifacts appear in literature since then, with real (and fraudulent) mechanical devices actually demonstrated to behave with some degree of intelligence. Some of these conceptual achievements are listed below under "Ancient History."

After modern computers became available, following World War II, it has become possible to create programs that perform difficult intellectual tasks. From these programs, general tools are constructed which have applications in a wide variety of everday problems. Some of these computational milestones are listed below under "Modern History."

ANCIENT HISTORY

Greek myths of Hephaestus and Pygmalion incorporate the idea of intelligent robots. Many other myths in antiquity involve human-like artifacts. Many mechanical toys and models were actually constructed, e.g., by Hero, Daedalus and other real persons.

5th century B.C.

Aristotle invented syllogistic logic, the first formal deductive reasoning system.

13th century

Talking heads were said to have been created, Roger Bacon and Albert the Great reputedly among the owners.

Ramon Llull, Spanish theologian, invented machines for discovering nonmathematical truths through combinatories.

15th century

Invention of printing using moveable type. Gutenberg Bible printed (1456).

15th-16th century

Clocks, the first modern measuring machines, were first produced using lathes.

16th century

Clockmakers extended their craft to creating mechanical animals and other novelties.

Rabbi Loew of Prague is said to have invented the Golem, a clay man brought to life (1580).

17th century

Early in the century, Descartes proposed that bodies of animals are nothing more than complex machines. Many other 17th century thinkers offered variations and elaborations of Cartesian mechanism.

Hobbes published The Leviathan, containing a material and combinatorial theory of thinking.

Pascal created the first mechanical digital calculating machine (1642).

Leibniz improved Pascal's machine to do multiplication & division (1673) and evisioned a universal calculus of reasoning by which arguments could be decided mechanically.

18th century

The 18th century saw a profusion of mechanical toys, including the celebrated mechanical duck of Vaucanson and von Kempelen's phony mechanical chess player, The Turk (1769).

19th century

Luddites (led by Ned Ludd) destroyed machinery in England (1811-1816).

Mary Shelley published the story of Frankenstein's monster (1818).

George Boole developed a binary algebra representing (some) "laws of thought."

Charles Babbage & Ada Byron (Lady Lovelace) worked on programmable mechanical calculating machines.

20th century - First Half

Bertrand Russell and Alfred North Whitehead published Principia Mathematica, which revolutionaized formal logic. Russell, Ludwig Wittgenstein, and Rudolf Carnap lead philosophy into logical analysis of knowledge.

Karel Capek's play "R.U.R."(Rossum's Universal Robots) opens in London (1923). - First use of the word 'robot' in English.

Warren McCulloch & Walter Pitts publish "A Logical Calculus of the Ideas Immanent in Nervous Activity" (1943), laying foundations for neural networks.

Arturo Rosenblueth, Norbert Wiener & Julian Bigelow coin the term "cybernetics" in a 1943 paper. Wiener's popular book by that name published in 1948.

Vannevar Bush published As We May Think (Atlantic Monthly, July 1945) a prescient vision of the future in which computers assist humans in many activities.

A.M. Turing published "Computing Machinery and Intelligence" (1950). - Introduction of Turing's Test as a way of operationalizing a test of intelligent behavior.

Claude Shannon published detailed analysis of chess playing as search (1950).

Isaac Asimov published his three laws of robotics (1950).
