The Claremont Hotel Club & Spa is a hidden gem in Northern California's East Bay. The full stories of this special place have remained largely untold. Complete historical pictures of this distinctive estate (currently hanging in the hotel lobby) have never been made available or widely disseminated, until now. For the first time, a collector's volume and historical narrative for the general public of The Claremont Hotel Club & Spa Centennial Commemoration - The First 100 Years (1915-2015) of an Oakland-Berkeley Landmark High Atop The Hill is now being made available. This book is a charitable calling by the author, as one of The Claremont Hotel Club & Spa's most appreciative patrons and self-described "closet historian and lover of great historic hotels." Inside this fascinating book are exclusive archives, fabulous photographs, extraordinary stories of residential and transient dwellers spanning over decades, previously untold until now. This book is the culmination of extensive research, several interviews, and numerous photographs, images, and hotel archives, being made available here to the general public, as a brief reference offering.
