Alan Turing,  man widely recognised as being  father of modern computer science, has been honored by being selected to appear on  United Kingdom banknote. Mr Turing was chosen ahead of  wealth of notable British historical figures and luminaries to be  face of  new £50 note. Turing was instrumental in helping Britain and its allies win World War II. He led  team of codebreakers to crack  Enigma code the Nazis used to send messages to warships and military commanders. He invented  now famous British Bombe to do this. This was a giant computer, which ushered in  birth of modern computing and  beginnings of artificial intelligence.
Alan Turing was  mathematical genius who also excelled in  sciences. He was born in London in 1912. He graduated from Cambridge University and then outlined his vision for creating  algorithm-based computing machine. He said of his invention: "This is only  foretaste of what is to come, and only  shadow of what is going to be." His idea is central to  computers we use today. His brilliance led to his being asked to join the WWII code-breaking team. Despite his pivotal role in ending that war, he was persecuted in  post-war years for being homosexual. Being gay was illegal in  UK until 1967. He chose to be chemically castrated rather than go to prison. Turing died in 1954, aged 41, in  apparent suicide.
