What did Simon Norton do after 1985? Simon Norton is a mathematician that worked on finite simple groups and co-authored the Atlas of Finite Groups. With John Conway they proved there is a connection with the Monster group and the j-function:monstrous moonshine
There's now a book out titled The Genius in my Basement by Alexander Masters, where he says that Simon Norton stopped doing mathematics after 1985 when John Conway left for America. I find this hard to believe because the book also talks about his immense talent and natural attraction to the subject as a youngster:

*

*while still at school, gained a first-class external degree from London university

*Won gold at the IMO between '67 and '69 and special prizes twice.

Did he continue to produce mathematical papers after 1985?
I suspect the answer is yes, and would love to know what he did after 1985.

He was teaching postgraduate students in the year 1987-88; I did Part III in Cambridge that year, where he lectured Reflection Groups.  The most interesting subject of all I took that year, and I regret not doing that subject in the final exam.
