Later he joined Leo Fantl in South Africa as systems manager on the LEO III in November 1960.  Returned to England after two years to join the consultants’ marketing LEO IIIs, and included Freeman’s Mail Order amongst his successes. Shortly after the return from South Africa LEO became EELM, a move Brian did not enjoy, deciding to join consultants Coopers and Lybrand.  This was the beginning of a long and successful career outside LEO embracing a number of companies, culminating with head of management services for British Oxygen.  After leaving British Oxygen Brian set up his own venture capital business

Abstract: After a degree in Industrial Economics at Nottingham University University joined LEO, having been impressed by the drive of the team from LEO interviewing him as part of the milk-round recruiting new graduates. By the time he joined  as a  as a programmer LEO had merged with English Electric. Worked as part of the team programming the Premium Bond application for the Post Office, but finding himself a not very good programmer acted as informal PA to David Caminer and moved successfully into Sales & Marketing covering Eastern European countries. Later joined Software Sciences as European Marketing Manager. Then formed his own company. The oral history includes fascinating anecdotes of his career with LEO and its successor companies.

Editor:  Frank Land

Abstract: Trained as an apprentice engineer and spent 7 years working with EMI.  Saw advert from LEO for engineer but wanted to leave engineering and applied to join LEO as a bureau programmer at Hartree House.  Joined LEO in 1962 just as LEO ii/5 wasw being pkased out for LEO III/1.  Worked, using first Intercode, then CLEO on a number of bureau applications including Heinz production control, and on the transfer of the Heinz bureau jobs from LEO II to their own LEO III.  Progressed rapidly becoming responsible for payroll and share registration applications. With the long-term future of LEO dubious enticed to Honeywell (UK) by a job offer that could not be refused, to work on their H200 operating system.  After 7 months I moved on to be a consultant for Hoskyns System Management which was being set up as a subsidiary to Hoskyns Consultancy and where the LEO experience was much more relevant.  Worked for them for seven years, but then found that the nomadic life that was required of consultants to advance was not compatible with having a young family so joined London Transport IT where and  worked for them for 20 years until retirement.

His programming career started with working on LEO II applications including the Glynn Mills Officers payroll under John Lewis and then progressed toto systems software working at Minerva Road.  After working on the Intercode translator took a key role in the design and programming of the CLEO compiler for LEO III. After the formation of EELM worked on System 4. Moved to Kidsgrove, keeping up his interest in the design of computer languages and as as a result of his expertise was assigned as an EELM representative under John Pinkerton  on ECMA. Continued working in this field until in the mid 80s interest in language and compiler design faded and as a result took early retirement at age 55.  Whilst at LEO married fellow programmer Margaret James, started family life and had 3 children.  In retirement he joined Congleton Sustainability Group and runs a Green Living course for Congleton U3A, and has acted on his life-long interest in cycling as secretary of the local cycling club.
