Incidentally, I have a homework assignment for the new World Atlas of Golf to do short bios of the 8-10 greatest Golden Age architects, and to include in a box their most important works -- hopefully 8-10 courses instead of 4-5. So there are two sets of arguments to have.
I think I've got to include Colt, MacKenzie, Alison (because of his influence in Japan and even South Africa), Ross, Simpson (because of his influence in Europe), Macdonald, Flynn, Tillinghast and Stanley Thompson. Don't know if I will dare to pick a tenth man from Thomas/Travis/Raynor/et al. But if any of the experts want to email me a list of the most influential works by their man, it would be much appreciated.
I do think every architect's first course should be included as among their most influential; for a couple I am not sure where it is. What was Stanley Thompson's first work? Or Tom Simpson's?
