I never met him, saw him interviewed on TV, or read any article by him but by all accounts he was a very nice guy.
With regards to his work, it's my understanding that his son basically took over many years ago. I haven't played a lot of his work, the Spey Valley course being the one course that I can think of off the top of my head, and perhaps the "Seve" course in Cumbernauld, the name of which has momentarily gone out of my head. Both have some really good golf holes but also some clunkers where you get the impression the routing was forced or it was done entirely on paper with no on site supervison to make sure it worked.
I'm also not a big fan of his style of bunkering, flat bunker bottoms and rounded humps in front. He re-did the bunkers at Killermont in that style to the detriment of the course IMO.
