Pioneer in bringing the LEO computer into active use for the UK catering enterprise J. Lyons and Company, Caminer took a leading role in developing the business applications and was in charge of all programming and systems work. When Lyons set up its computer subsidiary, LEO Computers Limited, Caminer became a director responsible for marketing and all systems work. Subsequently, on the Government-sponsored consolidation of the UK computer manufacturers, he took a senior role in the resultant company, ICL.
David is recognized as a true pioneer, having invented many of the standards now called systems engineering (Aris, 2000, Caminer 2003). Many of those who worked for him owed their success to the rigorous methods and quality standards Caminer insisted on.
After retirement, David established the LEO Foundation and was the principal author of the book "LEO: The Incredible Story of the World's First Business Computer" (Caminer et al, 1998).
