This year's AM Turing Award has been given to Charles Thacker, the designer who made history by developing a computer in three months in the 1970s.
Awarded by the Association for Computing Machinery, the AM Turing Award is sometimes called the Nobel prize of the computing world.
Thacker was honoured for the design and realisation of the Alto computer, but the Association also recognised his other contributions to the industry.
These include networking computers and developing the computer screens that made modern graphical user interfaces a reality.
The Alto, which Thacker developed at Xerox's Palo Alto Research Centre in just three months, was the inspiration for Apple's Lisa and Macintosh computers and was also the forerunner of the engineering workstation.
