odebreaker is an exhibition developed by the Science Museum to celebrate the centenary of the birth of this pioneering British figure.

Alan Turing is most widely known for his critical involvement in the codebreaking at Bletchley Park during the Second World War. But Alan Turing was not just a codebreaker.

This British mathematician was also a philosopher and computing pioneer who grappled with the fundamental problems of life itself. His ideas have helped shape the modern world, including early computer programming and even the seeds of artificial intelligence. This exhibition tells the story of Turing and his most important ideas.

At the heart of the exhibition is the Pilot ACE computer, built to Turing’s ground-breaking design. It is the most significant surviving Turing artefact in existence.

Alongside this remarkable machine is a sequence of exhibits showcasing Turing’s breadth of talent. Together with interactive exhibits, personal recollections and a wealth of historic imagery, the exhibition offers an absorbing retrospective view of one of Britain’s greatest twentieth-century thinkers.

At Bletchley Park, Buckinghamshire, thousands
of men and women laboured night and day to
crack these coded radio messages which held
Germany’s most secret plans. One of these
codebreakers was Alan Turing.
But Turing was not just a codebreaker. Born
100 years ago, this British mathematician was
also a philosopher and computing pioneer
who grappled with some of the fundamental
problems of life itself. Yet his own life was cut
tragically short. In 1954 he was found dead,
poisoned by cyanide. He was 41.

Electrical logic machine by Dietrich Prinz and Wolfe Mays

This machine was made at Manchester University by physicist Dietrich Prinz, one of Alan Turing’s protégés, and Wolfe Mays, a 36-year-old philosophy lecturer.

It is an electrical device for testing logical propositions, built mostly from RAF spare parts left over from the Second World War, and was unique in Britain at the time.

The Pilot ACE computer

his was one of the first electronic ‘universal’ computers. Its fundamental design was by Alan Turing, who wrote the specification in 1945 while working at the government’s National Physical Laboratory. It was completed in 1950.

Turing’s idea was to build a large computer, to be known as the Automatic Computing Engine or ACE. But slow progress, coupled with changes in project direction imposed on Turing, left him deeply frustrated, and he quit in 1948. This small-scale trial version, called Pilot ACE, was completed in his ab
