A few Simonds-oriented books have come out in the last year. Check them out:
Graceland Cemetery: A Design History just came out which covers O.C. Simonds role in the landscape design of the cemetery. Sadly I have never been to this cemetary (keep having it on my list when I visit Chicago), and have not read the book yet.
Mountain by Sandy Hill is a great (and huge) coffee table photo book that just came out all about mountains and the history of mountain climbing. Sandy Hill is a famous climber who also barely escaped death on Everest in 1996 captured in the book Into Thin Air. I was approached more than a year ago to include a photo in the book. Great to see it finaly come out.
Low-Key Genius is a biography of the work of O.C. Simonds by Barbara Geiger which came out in May, 2011.
