This is the only book I have found with highly detailed information about Ernest Coxhead, Willis Polk and A.C. Schweinfurth. The other architect featured here is Bernard Maybeck, who has been written about in other books. This book is excellent at showing how the works of these four architects were influenced by their mentors, such as A. Page Brown, Mckim, Mead & White, Daniel Burnham, and how their work influenced each other into what was to be known as the San Francisco Bay Regional style. As any architecture book should be, it is well illustrated with photos and drawings of the works of these architects, as well as examples of buildings that influenced them.
