## Varieties of Groups

I did this work for my doctoral thesis under the supervision of
Peter Neumann who was one of the most important figures in my mathematical
development. Varieties of groups are classes defined by identical relations
and, in the 1960s, it was a hot question whether there existed varieties
which needed an infinite number of defining relations. Once this question
was answered (there are!) the study of varieties somewhat died away. I'd
like to say that I was so far-sighted a mathematician that I left the
subject voluntarily - but that would be a lie.
