Alan Turing

Jun 23, 1912

Jun 7, 1954

Alan Turing was one of the greatest British mathematicians, logicians, and computer scientists who introduced the principles of modern computing and artificial intelligence. Turing was born on June 23, 1912, in Maida Vale, London, and demonstrated outstanding intellect and curiosity even in childhood. He started his education at Sherborne School and then continued at King's College, Cambridge, where he obtained a first-class degree in mathematics. 1936, Turing published On Computable Numbers, with an Application to the Entscheidungsproblem. In it, he introduced the idea of a universal machine, which we now call the Turing Machine. This theoretical framework became a foundation of computer science and proved what computers could and could not do. Turing attended Princeton University and received his Ph.D. with Alonzo Church as his supervisor. Turing actively participated in the Second World War and was part of Bletchley Park, the British code-breaking center where he designed methods of decrypting the German Enigma machine. He played a vital role in the victory of the Allied forces, preventing the loss of many lives through the interception of essential messages from the enemy. In 1946, Turing was awarded an Officer of the Order of the British Empire in recognition of his contribution to the war. After the war, he joined the National Physical Laboratory, where he created the Automatic Computing Engine (ACE), one of the first computer designs that used stored programs. The principles that governed his thinking in artificial intelligence are well captured in his 1950 paper titled 'Computing Machinery and Intelligence,' where he presented the famous Turing Test that measures the intelligence of a machine in its ability to mimic human behaviour. However, he had his private struggles and problems because he was a homosexual and homosexuality was forbidden in the UK in those years. In 1952, he was convicted of 'gross indecency' and was treated with chemical castration. The persecution that he went through forced him to take his own life on June 7, 1954, at his home in Wilmslow, Cheshire. Many honours and recognitions have been given to Alan Turing even after his death. In 2013, the UK government decided to posthumously acquit him of the charges, thus admitting that he was wronged in the worst possible way. His works are still considered significant in mathematics, computer science, and cryptography today.

Life and achievements

Early life

Alan Mathison Turing was born on June 23, 1912, in Maida Vale, London. His father, Julius Mathison Turing, worked in the Indian Civil Service while his mother, Ethel Sara Turing, was the daughter of the chief engineer of the Madras Railways. As a child, Turing was fond of mathematics and science and was known to be very intelligent compared to his other children. Frequent moves characterized Turing's early school years because his father changed posting to India. He was at St. Michael's, a preparatory school, where he was first identified as a genius. He started his formal education at the Sherborne School in Dorset, a famous boarding school, in 1926. Turing struggled with other subjects that could have been more interesting; however, he developed an interest in science, especially chemistry and mathematics. Turing joined King's College, Cambridge 1931 to read for the Mathematics tripos. He was to spend some of the happiest years at Cambridge; he flourished in the academic ambiance and obtained first-class honours in 1934. He also contributed to developing probability theory, which earned him a fellowship at King's College, enhancing his educational status.

Legacy

It is hard to overestimate Alan Turing's impact on the development of science and technology; his contributions affected many fields. Thus, his concept of the Turing Machine gave a theoretical foundation for the growth of computer science and its capabilities by proposing a machine that can compute any task given a proper algorithm and tools. This theoretical construct is still relevant in computer science even to this day. Turing's contributions during the Second World War at Bletchley Park significantly influenced the war's outcome. Thus, by creating methods to decrypt the Enigma code, Turing and other Bletchley Park members helped the Allies intercept important German messages, bring the war to a faster end, and save millions of lives. He contributed to the development of cryptography and developed the foundation of the encryption techniques used today and cybersecurity. After his death, Turing was recognized and awarded for his work. The first Turing Award, presented in 1966 by the Association for Computing Machinery (ACM), is commonly known as the Nobel Prize for Computing. His life has been recounted in many films, books, and plays; therefore, it has become part of popular culture and people's consciousness. In the last few years, attempts to pay tribute to Turing and right the wrongs he suffered because of his homosexuality have been made. The UK government's official apology in 2013 and the \"Alan Turing law\" in 2017 that pardoned men convicted of historical homosexual charges are evidence of his influence on science and social change. Turing's work continues after his technical contributions; his approach to problem-solving, which fuses math, biology, and philosophy, is still relevant today. He is one of the pioneers of Artificial Intelligence, and his contribution to this field, especially the Turing test, is still used today as a basis for discussions in the field.
