After doing research into radar systems and receiving a PhD at Cambridge, Maurice Wilkes recommended John Pinkerton to J Lyons & Co as the engineer to design and develop LEO. He joined Lyons in January 1949 and started to build the small team of engineers which succeeded in building LEO I, a machine based on the EDSAC design but significantly modified for business data processing.
In 1959 he was appointed a Director of LEO Computers Limited, but resigned on the merger creating English Electric Leo Marconi (EELM). On the further creation of ICL he took charge of research into the product lines being developed by EELM.
Subsequently John Pinkteron took a leading role in the development of International Standards and represented the UK in bodies such as the European Union’s ESPRIT project. He also became Chairman of the editorial board of the ICL Technical Journal.
As a tribute to his outstanding qualities the IET inaugurated an annual Pinkerton Lecture and the Worshipful Company of Information Technologists (WCIT) set up an annual Pinkerton Award to the year's leading apprentice.
