Alan Mathison Turing, OBE, FRS (23 June 1912 – 7 June 1954), was an English mathematician, logician, cryptanalyst, and computer scientist. He was influential in the development of computer science and providing a formalisation of the concept of the algorithm and computation with the Turing machine, playing a significant role in the creation of the modern computer.

For his monumental achievements and vast influence the Church of Virus voted for Turing's illumination as a VirianSaint on March 21, 2010. Meridion vote.
Often considered the founder of computer science, Alan Turing's work in mathematics led him to envision the first digital computer. The Turing Machine would read a series of ones and zeroes, interpreting them to perform an ordered and repeatable sequence of steps. His machine introduced the concept of the multi-purpose computer. His concepts introduced the algorithm as a means of solving any problem by way of a sequence of well-conceived steps.
Turing's interest in biological processes and his belief that a machine could be created to mimic the process of the human brain ushered in the era of artificial intelligence. He conceived of the Turing Test, a method of proving or disproving the presence of intelligence in a machine. If an objective observer, by way of questions posed from a keyboard, could not reliably identify a machine from a person, the machine would have passed the Turing Test. Successful achievement of the test remains a primary goal of today's artificial intelligence researchers.
During World War II, Turing was an instrumental member of the team from the Department of Communications in Great Britain that deciphered German codes generated by the Enigma machine.
In recognition of his monumental achievements in the advancement and realization of computers and computer science, significant contributors to the field are recognized by the A.M. Turing Award. Bestowed by the Association for Computing Machinery and sponsored by Intel, the award recognizes major contributions of lasting significance to the computer field. Its list of recipients constitutes a veritable Who's Who of computer science.
Turing was awarded an undergraduate degree in mathematics from King's College, Cambridge, in 1934. He received a Ph.D. from Princeton in logic, algebra, and number theory in 1938. He was a fellow of King's College and of the Royal Society, and a recipient of the Order of the British Empire (OBE). (from http://www.sis.pitt.edu/~mbsclass/hall_of_fame/turing.html)
Turing never described himself as a philosopher, but his 1950 paper “Computing Machinery and Intelligence” is one of the most frequently cited in modern philosophical literature. It gave a fresh approach to the traditional mind-body problem, by relating it to the mathematical concept of computability he himself had introduced in his 1936-7 paper “On computable numbers, with an application to the Entscheidungsproblem.” His work can be regarded as the foundation of computer science and of the artificial intelligence program.
