3. Introduction Born :- June 23, 1912 Died :- June 8, 1954 Who was Alan Turing? He is a British pioneering computer scientist, mathematician, logician, cryptanalyst and a mathematical biologist, who is considered to be the father of theoretical computer science and artificial intelligence. Alan Turing was responsible for breaking the Nazi Enigma code during World War II. He was a London boy, an Olympic-level runner, a philosopher, and a man that was ahead of his time with an understanding of human needs that is more akin to ours today. Alan Turing was not a well known figure during his lifetime. But nobody truly appreciated his efforts until decades later when the information was released to the public.

4. Early Life He got bad to mediocre grades in school and frustrated his teachers But there were some teachers who noted his abilities at an early age. The headmistress of his primary school once wrote that she: “had clever boys and hardworking boys, but Alan is a genius.” Alan Turing spent much of his early life separated from his parents, as his father worked in the British administration of India. At 13 years old, he was sent to Sherborne School, The rigid education system gave his free-ranging scientific mind little encouragement, so Turing studied advanced modern scientific ideas, such as relativity, on his own, running far ahead of the school syllabus . Discouraged at school

5. At 13 years old, he was sent to Sherborne School a large boarding school in Dorset. Career & Education In 1931, Turing began studying mathematics at King's College, Cambridge, where he developed his interest in the theory of computability. Later, He went to study under mathematician Alonzo Church for two years and it was here he became involved in cryptologyt and finally recieved Ph.D. from Princeton University in 1938

6. Contribution H e released of his paper On Computable Numbers. H e mentioned the hypothetical Turing Machine and therefore gave birth to the idea of the modern computer. Breaking the Enigma code:- After September 1939, joined by other mathematicians at Bletchley Park, Turing rapidly developed a new machine (the ‘Bombe’) capable of breaking Enigma messages on an industrial scale. Designs a first electronic computer:- In March 1946 Turing produced a detailed design for what was called the Automatic Computing Engine ACE. This was a digital computer in the modern sense, storing programs in its memory. His report emphasised the unlimited range of applications opened up by this technological revolution, and software developments ahead of parallel American developments . In 1950, he published a philosophical paper including the idea of an ‘imitation game’ for comparing human and machine outputs, now called the Turing Test. This paper remains his best known work and was a key contribution to the field of Artificial Intelligence .

7. Personal Life Alan Turing fell in love with another able pupil, Christopher Morcom. He was inspired to communicate more and also to become an academic success. But Christopher died suddenly from tuberculosis. Devastated, Turing wanted to believe that Christopher’s mind somehow lived on. His emotional turmoil involved a scientific fascination with the problem of mind and brain that underlay his later work. He stuttered when talking- he notes that a BBC radio producer had called Turing a very difficult person to interview for that reason.He “took his time finding the right words,” he explained

8. Personal Life Convicted for gross indecency :- All male homosexual activity was illegal until 1967, and Turing was prosecuted when an affair with a young man came to the notice of the police. The punishment for homosexuality was chemical castration, a series of hormone injections that left Turing impotent. He refused to let a punishment of chemical castration stop him from working

10. Death & Legacy Alan Turing was found dead in bed by his cleaner on 8 June 1954. He had died from cyanide poisoning the day before. A partly eaten apple lay next to his body. After many years of petitioning the government, Alan Turing was pardoned by Her Majesty Queen Elizabeth II on Christmas Eve, 2014. The Alan Turing Law is now an informal name for the exoneration of other men convicted for crimes based on their sexuality. The Bank of England's £50 note now features a portrait of Alan Turing, released into circulation on what would have been his birthday on 23 June 2021. The ACM A. M. Turing Award is an annual prize given by the Association for Computing Machinery (ACM) for contributions of lasting and major technical importance to computer science. It is generally recognized as the highest distinction in computer science and is colloquially known as or often referred to as the "Nobel Prize of Computing"

11. Quote ““Sometimes it is the people no one can imagine anything of who do the things no one can imagine.” ~ Alan Turing

12. Conclusion One of the main conclusions that can be drawn from Alan Turing's biography is the importance of acknowledging and valuing diversity in society. Turing's life and work demonstrate how society's prejudice and discrimination can hinder the progress and development of brilliant minds, as well as cause immense personal suffering. Another important lesson from Turing's life is the value of perseverance and determination in pursuing one's goals. Despite facing numerous challenges and setbacks throughout his life, Turing remained dedicated to his work and continued to make significant contributions to the fields of computing and cryptography ,
