Eric,
You obviously haven't been following along here, as that is not the way this game works! TMac provides things from time to time from his collection, but more often, he doesn't, while whining when others don't provide him to access to their stuff.
TMac,
Some have complained about your various lists being too long. I have an idea for a shorter list you could provide - how about a list of courses from the pre-Golden Age that you believe are correctly attributed as to design!
Seriously, I certainly understand the desire to drill down and know just how things happened in those days, like how much Owners influenced the design, how the process differed from today when the whole notion of designing courses in America was still being formed, etc. It is quite possible that in a complicated process, there are usually some unsung heros who should get more credit than perhaps previously given, either for an individual feature, or for inspiration, etc. As an example, the guys who built MacKenzie's bunkers obviously helped create his legend, but he is still the gca of record. A few years ago, though, one of his bunker builders got in the CA Golf Hall of Fame, so more recognition of all involved is certainly the trend.
I am just not sure we will ever know from records provided and the best we can hope for is nuggets of deeper info, and not revelations that the attribution should be changed. I presume people in those days were probably 99% correct in their recordings of what happened. If they wanted to credit Tillie for Shawnee, there is probably a good reason for it, even if others made contributions of some kind.
I may not be clear in my thoughts, but I wonder if a thread title that simplfies in black and white a question about design attribution, for a thread that is really trying to find out deeper, more complex roles and attributions is simply not one that can't help but start an argument, whether intentionally or not?
