Commonly name to as the father of computer science , Alan Turing was a bright mind that paved the fashion for computers as we know them .   With a squad of code - circuit breaker atBletchley   Park , England , Turing   broke the infamousEnigma codeused by the Nazis in WWII using an advanced machine akin to a advanced computer and invented the idea of a " Universal political machine " that could execute instruction and run programs . His employment was inbuilt in found the study of computer science , alongside   being one of the key contributor to Artificial Intelligence with the creation of theTuring Test .

Despite his unbelievable feats , Alan Turing   was considered shamefaced of one affair – he   was homosexual .

A crime in 1952 , Turing ’s queerness found himprosecutedfor gross impropriety   and dependent to hard punishment . He was unapologetic in who he was and was subsequently forced to take a treatment that would chemically castrate him , all whilst   receiving poor discussion from both society and the government .   A man   whose work   saved   an forecast   14 - 28 million sprightliness was ban and   provoke repeatedly by police and largely limit to his house .

In 1954 , Turing take his own life history after   eat   an orchard apple tree laced with cyanide .   Although he was pardon in 2013 , the expiration of Alan Turing is   often   visit as one of the British Government ’s greatest failings .

Now ,   theBank of Englandhas released their in vogue and last polymer banknote purpose , featuring Alan Mathison Turing   as the face on the front .   The raw bank note is supposedly the most safe bank bill yet , turn back various   nods to the mathematician ’s great workplace and paying homage to his life . The Bank will also be fly a rainbow iris in his   honor   above the Threadneedle Street   headquarters in London .

" He was a conduce mathematician , developmental biologist , and a pioneer in the flying field of computer scientific discipline , ” said   Andrew Bailey , the regulator of the Bank of England , in astatement .

" He was also festal , and was treated appallingly as a result . By invest him on our new polymer £ 50 banknote , we are lionise his achievements , and the values he symbolises . "

In jubilation of the release , GCHQ , one of the UK government ’s chief intelligence and security department agencies , has announced theTuring Challenge , releasing their difficult Seth of puzzle yet . Are you smart enough to crack the code on the £ 50 tone ? incur outhere .

The English banknote   has see a number of redesigns across the various appellation over the past decade , as the   Bank of England switches from traditional report to plastic up-to-dateness .   New nominal head have made their style onto the bill , include fabled author Jane Austen and ex - Prime Minister Winston Churchill . The £ 50 redesign is the last to be unveil , with £ 50 preeminence rarely seeing habit in day - to - day exchanges . Still , the short letter remains in circulation as the UK ’s highest designation , and the Modern bill will be issued for the first fourth dimension on June 23 – Turing ’s birthday .
