My grandfather worked at the Ahwahnee for 19 years, 1927-1946. I wrote a biography of him for the family, but the Yosemite years may have general interest to Yosemite lovers, and special interest to Ahwahnee lovers and rock climbers as Willem Kat was one of the pioneers. Volume IV, linked below, is 193 pages, but it has detailed contents and an index which may allow you to focus in on an item of interest. Lots of photos.
Did you know that the floor boards in the bungalows represent notes in musical pieces? Did you know that a Schubert song is carved in the ceiling molding of room 723? These were things done out of my grandfather's imagination as they pretty much left him alone.
Dave Brower and Ansel Adams are also in there.

I should also mention the interview with Ranger Naturalist Douglass Hubbard in Volume I as it is a classic.
