Hi John,
Intersting timing...I just got back from an event today at San Geronimo Golf Course which was Mr. Macan's last course he designed before he passed away in 1964 (course opened in 1965 just after he died). Our community grassroots coalition in West Marin is fighting to save the golf course from permanently closing and is running a campaign for a county ballot initiative to save the course next March:

Over the last two years I've researched Macan quite a bit and now have a much greater appreciation and admiration for his work. Michael Riste is a tremendous resource and his book is full of great insight. He actually has a plasticine model in the British Columbia Golf Museum of the 3rd green at San Geronimo that Macan built (apparently he built a lot of models for clients).
If you're interested I'd be happy to send you a letter I put together for our country Board of Supervisors that outlines Macan's career and his significant contributions to golf in the Pacific Northwest.
Are you interested in a particular Macan course or his career more generally?
Cheers,
Josh
P.S. I think Macan is the only architect who worked pre-WWI, the interwar period, and after WWII. His career as a golf architect spanned 53 years, which I've always thought was the longest of any architect I can think of, but these days Mr. Dye may have surpassed him.
