Les Mustoe was one of the early users of Atlas and particularly the SC4020. He was interested in the possibilities that computer graphics and computer animation had in improving the way mathematics was taught to students of engineering.
Using the SC4020 soon after its arrival was quite difficult and he spent significant periods in 1968 and 1969 with Paul Nelson debugging the SC4020 animation cameras and the SCFOR Fortran system to produce good quality output. One of the animations was showing viscous flow.
The use of computer animation for education and research was the theme of the first Computer Animation Symposium held in the UK at the Atlas Laboratory on 30th July 1971.
John Hallas and Les Mustoe both talked about the needs of the university lecturer while Jon Ogborn (Nuffield Foundation), Judah Schwartz (MIT) and John Richmond (BBC, Open University) gave examples of educational material being generated. The Finacial Times reported the event by writing: The subject of computer animation flared into prominence in the last fortnight when a one-day symposium was held by the Science Research Council at the Atlas Computer Laboratory in Didcot. This seems to be the spiritual home of the craft in Britain.
After a period at Essex University he moved to Loughborough University in 1969 and lectured there until 2009.
After his retirement he taught voluntarily at Hitchin Grammar School where he went to school.
He died on 19th December 2017.
Incidentally, Bob Hopgood and Alan Francis of the Graphics Section at Atlas at the time also went to Hitchin Grammar School.
