The time Turing spent at NPL left a noticeable mark on its computing legacy. His original plans for the ‘electronic brain’ led to the construction of the Pilot ACE computer, the fourth general-purpose stored-program digital electronic computer in the world. This led to the production of the DEUCE computer – an upgraded, commercial version of the Pilot ACE – and finally, in 1958, the ACE computer itself.

However, this is not the only achievement to have begun while Turing was at NPL. One of the members of the ACE team, Donald Davies, went on to develop packet-switching: a process that combines computers and communications, and a vital part of the internet system that we use so much today.

There are also plenty of other computing achievements that NPL has played a major part in, including pattern recognition software, language translation, and the first local area network in the world.
