Alan Mathison Turing, OBE , fue un matemático, lógico, científico de la computación, criptógrafo, filósofo, maratoniano y corredor de ultra distancia británico.

Es considerado uno de los padres de la ciencia de la computación y precursor de la informática moderna. Proporcionó una influyente formalización de los conceptos de algoritmo y computación: la máquina de Turing. Formuló su propia versión de la hoy ampliamente aceptada tesis de Church-Turing .

Durante la Segunda Guerra Mundial, trabajó en descifrar los códigos nazis, particularmente los de la máquina Enigma, y durante un tiempo fue el director de la sección Naval Enigma de Bletchley Park. Se ha estimado que su trabajo acortó la duración de la Segunda Guerra Mundial entre dos y cuatro años. Tras la guerra, diseñó uno de los primeros computadores electrónicos programables digitales en el Laboratorio Nacional de Física del Reino Unido y poco tiempo después construyó otra de las primeras máquinas en la Universidad de Mánchester.

En el campo de la inteligencia artificial, es conocido sobre todo por la concepción del test de Turing , un criterio según el cual puede juzgarse la inteligencia de una máquina si sus respuestas en la prueba son indistinguibles de las de un ser humano.

La carrera de Turing terminó súbitamente tras ser procesado por homosexualidad en 1952. Dos años después de su condena, murió —según la versión oficial por suicidio; sin embargo, su muerte ha dado lugar a otras hipótesis, incluida la del asesinato—. El 24 de diciembre de 2013, la reina Isabel II promulgó el edicto por el que se exoneró oficialmente al matemático, quedando anulados todos los cargos en su contra.

„These questions replace our original, "Can machines think?"“

—  Alan Turing
Context: "Can machines think?"... The new form of the problem can be described in terms of a game which we call the 'imitation game." It is played with three people, a man (A), a woman (B), and an interrogator (C) who may be of either sex. The interrogator stays in a room apart front the other two. The object of the game for the interrogator is to determine which of the other two is the man and which is the woman. He knows them by labels X and Y, and at the end of the game he says either "X is A and Y is B" or "X is B and Y is A." The interrogator is allowed to put questions to A and B... We now ask the question, "What will happen when a machine takes the part of A in this game?" Will the interrogator decide wrongly as often when the game is played like this as he does when the game is played between a man and a woman? These questions replace our original, "Can machines think?"

„Mathematical reasoning may be regarded rather schematically as the exercise of a combination of two facilities, which we may call intuition and ingenuity.“

—  Alan Turing
Context: Mathematical reasoning may be regarded rather schematically as the exercise of a combination of two facilities, which we may call intuition and ingenuity. The activity of the intuition consists in making spontaneous judgements which are not the result of conscious trains of reasoning... The exercise of ingenuity in mathematics consists in aiding the intuition through suitable arrangements of propositions, and perhaps geometrical figures or drawings. "Systems of Logic Based on Ordinals," section 11: The purpose of ordinal logics (1938), published in Proceedings of the London Mathematical Society, series 2, vol. 45 (1939) In a footnote to the first sentence, Turing added: "We are leaving out of account that most important faculty which distinguishes topics of interest from others; in fact, we are regarding the function of the mathematician as simply to determine the truth or falsity of propositions."

„The view that machines cannot give rise to surprises is due, I believe, to a fallacy to which philosophers and mathematicians are particularly subject. This is the assumption that as soon as a fact is presented to a mind all consequences of that fact spring into the mind simultaneously with it. It is a very useful assumption under many circumstances, but one too easily forgets that it is false.“

This is the assumption that as soon as a fact is presented to a mind all consequences of that fact spring into the mind simultaneously with it. It is a very useful assumption under many circumstances, but one too easily forgets that it is false. A natural consequence of doing so is that one then assumes that there is no virtue in the mere working out of consequences from data and general principles. p. 451.
