This beautiful mid-century jewel box was designed by a Palo Alto architect named Donald Grier Hannum who is virtually unknown today. Hannum built a successful practice for himself after returning home from World War II, eventually opening an office with his high school classmate William Arthur Whifler. However Hannum passed away unexpectedly at the age of 33 the same year that this home was completed. Whifler would go on to a career of some renown, collaborating on the Burlingame City Hall and helping to found the architecture school at College of San Mateo.
It is difficult to predict what impact Hannum could have had if he had been given the opportunity to fulfill his promise over the course of a full career, but if this Orinda home is any indication, his early passing was quite a loss to the architectural community in the Bay Area.
