Having qualified as a chartered electronics engineer in 1969, he expanded into marketing and sales at an early age and then into international business management.
He considers himself to be fortunate to enter the computer industry while still in his twenties at the birth of the personal computer boom. In 1969, while with Ferranti, he launched the Argus 600, the UK’s first minicomputer. At 34, John was Chief Executive of the German and French subsidiaries of the Data Recording Group, Europe’s largest computer hardware manufacturer at the time, and 3 years later, Vice President-Europe for the Telex Corporation of America.
1979 saw the start of his own companies spanning the fields of hardware and software development, systems manufacturing and consultancy with a global customer base. There were few in the computer industry at the time and he wrote many articles over the years for the technical press and broadcast on computer matters for the BBC. He was also the technology contributor for the Government’s Diplomatic Handbook, which went to British Embassies around the world.
