Chip,
Dye was a minimalist once, but had to keep outdoing himself.
As for the original question, I have always - just based on feel - thought Muirfield was the first modern golf course, dating to 1892, I think. It has no blind holes, and a similar scale and bunker placement that was less "random" than earlier. All the great Scottish courses before that had blind holes, smaller greens (old course excepted.....) and more quirk, while Muirfield appears "designed."
As always, just my opinion.
