THE ARCHITECT—JOHN HANS OSTWALD
A modernist with a deeply human touch, John Hans Ostwald brought a rare depth of intellect and cultural sensitivity to mid-century architecture in the Bay Area.
Born in Berlin in 1913 to an upper-middle-class Jewish family, Ostwald earned a law degree in Vienna, studied briefly at the London School of Economics, and trained as a classical pianist before turning to architecture. He completed his architectural studies in Zurich before fleeing Europe with his wife, Rosemarie, in 1939. The couple arrived in San Francisco just as modernism was taking root in California—and Ostwald was quickly hired by renowned architect Richard Neutra, a family connection and one of the movement’s most influential figures.

established his own practice in Berkeley, designing from a modest studio of his own creation on Shattuck Avenue
Deeply influenced by Swiss functionalism and European intellectualism, his work married clean, modern forms with a strong sensitivity to landscape, lifestyle, and client character. He disliked rigid abstraction, preferring to tailor each home to the way his clients actually lived.
Among his major works are Berkeley’s Bancroft Center, the now-demolished South Branch Library, and a number of distinctive private residences across the East Bay and Marin County—including his final design, St. John’s Presbyterian Church, completed posthumously in 1973 by his partner E. Paul Kelly.
The Kellogg House stands out as a defining early example of Ostwald’s architectural voice
Rooted in the ideals of modernism, but resisting its coldness, its layout responds organically to the terrain and climate, enclosing a central terrace and breezeway that create privacy, protection, and fluid indoor-outdoor living. The home was recognized in Arts & Architecture Magazine in 1950 for its thoughtful simplicity and climate-conscious design.

A committed environmentalist and civic voice
Ostwald was active in the Sierra Club, a lecturer at UC Extension and the College of Environmental Design, and a leading force behind the City of Berkeley’s Sign Ordinance. He served on the Civic Art Commission and Design Review Committee, and was known for his public engagement in architectural, educational, and environmental issues throughout the 1960s and early ’70s.
John Hans Ostwald passed away in 1973, but his architectural legacy lives on in homes like The Kellogg House—spaces that reflect not only modern design ideals, but a life fully lived and deeply considered.
