In the early eighties, for example, he brought to Oxford the creators of two major formal specification languages: Cliff Jones with VDM, Jean-Raymond Abrial with Z. At Oxford, Z actually underwent a systematic rework, reminiscent of the Goethe quip reproduced above, with Frenchmen and mathematicians replaced by English mathematicians (or computer scientists). The new version enjoyed immense success in Britain, won a Queen’s Award and was used not only academically but in many mission-critical applications in industry, leading to a number of startups and work by such researchers (all having gone through Oxford at some point) as Jim Woodcock, Carroll Morgan, Jim Davies, J. Michael Spivey, Ian Hayes and Ib Holm Sørensen.

This was the world I walked into in 1986 as an undergraduate studying Mathematics and Computation. I was quite quickly indoctrinated in the ways of Z notation [1] and CSP [2] and had to learn to program in ML. I still have all the lecture and class notes and they are quite fascinating to look at so many years later. Funny to read the names of celebrated researchers that I just thought of as "the person who teachers subject X". I do recall Carroll Morgan's teaching being very entertaining and interesting. And I interacted quite a bit with Jim Davies, Jim Woodcock and Mike Spivey.

Having decided I wanted to stay and do a DPhil I managed to get through the interview with Tony Hoare (hardest question: "Where else have you applied to study?" answer: "Nowhere, I want to stay here") and that led to my DPhil being all CSP and occam [3]. I seem to remember we had an array of 16(?) transputers [4] that the university had managed to get because of a manufacturing problem (I think the dies were incorrecty placed making the pinouts weird, but someone had made a custom PCB for it).

Imagine my delight when Go came around and I got to see CSP in a new language.
