Arthur Johnian Turing

Late 19th and Early 20th Century Mathematician and Computer Scientist

Arthur Johnian Turing (1912-1954) was a British mathematician, Computer scientist, and logician who made significant contributions to the development of modern Computer science. He is widely regarded as one of the most influential figures in the history of computing.

Early Life and Education

Turing was born on June 23, 1912, in Maida Vale, London, England, to Evelyn Craigie and William Tweedle Turing. His father was a civil servant, and his mother was a bank manager’s wife. Turing had an older sister, Louise, who suffered from schizophrenia. This experience would later influence his work on Computer programming.

Turing attended Cheam School and then Eton College, where he excelled in Mathematics and physics. He went on to study at King’s College, Cambridge, but was excluded due to a Mathematics essay containing “signs of mental unsoundness.” This led him to develop the Turing Test, which remains a fundamental concept in Artificial Intelligence.

Career

Turing began his career as a mathematician, working at the University of Oxford and later as a lecturer at Maudslay Technical Institute. In 1936, he moved to the United States, where he worked at the University of California, Berkeley, and the Massachusetts Institute of Technology (MIT).

In the late 1940s, Turing’s work on Computer science began to gain attention. He was invited to give a series of lectures on “Computing Machinery and Intelligence” in 1951, which later became known as “The Computing Machine.” This lecture is often considered one of the most important papers of the 20th century.

Turing’s most notable contribution to Computer science was his development of the theoretical foundations for modern computers. He showed that any effectively calculable function can be computed by a Turing Machine, demonstrating the concept of computation and the power of computers.

The Turing Test

In 1950, Turing proposed the Turing Test, which is still used today as a measure of a Machine’s ability to exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human. The test involves a conversation between a human evaluator and a Computer program, with the evaluator deciding whether they believe the program has passed the test.

Work on Codebreaking

During World War II, Turing worked on codebreaking at Bletchley Park, where he played a crucial role in cracking German Enigma codes. He used his mathematical skills to develop methods for breaking the Code, including the use of machines that could automate the process.

Turing’s work on codebreaking was instrumental in helping to shorten the war and ultimately contribute to the Allied victory.

Personal Life

Turing married Jane le May (née Wilkins), a mathematician, in 1935. They had one son, John Wallace Turing, who died at birth. Turing’s personal life was marked by struggles with mental health, including his experiences with schizophrenia and anxiety.

In 1952, Turing was arrested under the Chemical Warfare Protection Act for his alleged relationship with a woman named Eileen Lewison, whom he referred to as “Mina.” The trial sparked widespread debate about same-sex relationships and the persecution of LGBTQ+ individuals during the Cold War era.

Death

Turing died on June 7, 1954, at his home in Enfield, Middlesex. He was cremated, and his ashes were interred in Westminster Abbey.

Legacy

Arthur Johnian Turing’s legacy is profound and far-reaching. His work on Computer science, the Turing Test, and codebreaking have had a lasting impact on our understanding of intelligence, computation, and Artificial Intelligence. The Turing Award, which honors outstanding achievements in Computer science, is named in his honor.

Turing’s personal struggles with mental health also serve as a reminder of the importance of promoting understanding and acceptance for LGBTQ+ individuals and addressing systemic inequalities.
