In the 1980s, on retirement from a successful career as a businessman in London and Australia N.M. Gwynne gradually took up teaching, at first privately. He soon found that he had a clear vocation and he discovered a real demand for his traditional methods, universal up to the 1960s but since displaced by new-fangled theories of learning. And so Mr Gwynne began to ply his trade in classrooms and lecture halls teaching a diverse range of subjects: English, Latin, Greek, French, German, mathematics, history, classical philosophy, natural medicine, the elements of music, even "How to start and run your own business." Now with an international word-of-mouth reputation, Mr Gwynne has been flown around the world in order to teach his pupils privately. And thanks to the Internet and Skype, he has sometimes found himself, within a single day's time, teaching children and adults in India, in Europe and the western United States.
