Educated at Plympton, King's Norton (won 2nd year prize) and Ilkley Grammar Schools. Went on to study Maths at Birmingham University (Edgbaston). Came First in First Year, Second in Second Year, and, by a natural progression Third in my Finals, (Which I didn't find out about until 2005, when I applied for the results of my Finals). Birmingham is sometimes regarded as the Fifth University in Country after Manchester, UMIST, Oxford and Cambridge. When I graduated in 1975 I was probably amongst the top 35 Mathematicians in the Country, I estimate, at a conservative estimate. (He says!)

Had mental problems after graduation. Only survived my first job at Marconi Elliott (Rochester) for four months. Stuck to my guns and joined Sperry Gyroscope, Bracknell, (taken over by B.Ae. in 1982) in March of 1978.

On 18-month Graduate Training Scheme (approved by EITB), put on Monte Carlo simulation of Mine Hunting Scenario. Totally analysed it statistically, but my predictions didn't seem to match the behaviour. It was only on leaving this part of my training, that they discovered that their random number generators were not coming up with means and standard deviations (spread around the mean) that the manufacturers specified. On finding the true means and standard deviations, my predictions agreed perfectly with the simulated behaviour. They were able to plot definitive graphs of the behaviour, as the parameters varied, and I saved them 1000's of computer hours.

On another part of my training, put on analysing a Russian Aero device with relays in it. It was only recently, on studying a Maths manual, I discovered a branch of Mathematics called 'Reliability Analysis'. I had independently performed a Reliabilty Analysis of the circuit. They didn't understand it, shoved it in a drawer, where a useless person found it, and claimed it as his own to hold on to his job.

Also spent time at Plymouth with Mk. 19 and 23 Gyros, joined the Dartmoor Ramblers and went Mirror dinghy sailing off Drake's Island.

Did Drawing Office Practice Training too.

Joined Image Processing Section of R & D, in the early days when you needed a 'framestore' to hold the image (1980).

Developed AGC Alogorithm, an 'edge-walking bug', a method of confirmation and deconfirmation of 'tracks', which I totally analysed statistically (as a random walk), and produced my 'magnum opus' in 1984 on a method called the S.S.D.A. One hundred pages of Maths, which they didn't understand, slapped a 'Confidential' sticker on, and stuck in a drawer, where it probably remains to today.

Also in 1984 combined two papers on Texture Measures and a Classification Method to produce a Texture Classification Algorithm. Left the Department, and another person took it over, got a 98% success rate from it, and based his whole career on it. It was at least 10-15 years ahead of its time. Now there is a whole Science of Textures.

Joined the Computer Services Dept. in 1985, learnt structured COBOL programming in record time, and wrote a report-producing suite of batch and on-line programs (custom design reports on-line) that was regularly producing 150 timed (weekly and monthly) reports a week, which went down to Plymouth, when they closed at Bracknell, and was finally removed from the computer in 1998, eleven years after I had completed it.

Also suite of raw COBOL 'pretty printing' and structure diagram-producing programs.

Got another job with RISL at Kingston and Henley - team 'migration' work (converting programs from one computer to another) for Provincial and TSB, before finally being made redundant in 1992.

Since then I have written about 80 poems, a novel (now published in 2010, with web site, 116 pieces of software (about 80 Acorn and 35 IBM applications), and three web sites in raw HTML.

I spent 20 years over a BBC Basic to Acorn ANSI C Translator, (the total 'C' source code is about 1.8 Mbytes) using a Bison (GNU Yacc clone 'compiler compiler') grammar for BBC Basic, a language that had no formal grammar in mind. My Dad said it was equivalent to writing a program to translate from pure Glaswegian into Latin.

Have also joined an Art Class and produced several reasonable pencil and watercolour drawings.
