Gyo Obata, Founding Partner at HOK, Dies at 99

Gyo Obata, FAIA, a world-renowned architect who cofounded HOK in 1955 with a vision for enhancing lives through building design, passed away on March 8, 2022. He was 99.


Gyo was one of three principals who built HOK from a regional, St. Louis-based architectural practice into one of the world’s most respected global design, architecture, engineering and planning firms. His distinguished career spanned six decades. From the time of his retirement in 2012 and continuing into 2018, Gyo maintained an office in HOK’s St. Louis studio, where he regularly served as a design advisor to his colleagues.

“Gyo’s extraordinary career at HOK continued into his 90s, and he served as a mentor to several generations of designers including myself,” said HOK Chairman and CEO Bill Hellmuth, FAIA. “As an example to all of us, he led HOK to become the largest architecture-engineering firm in the United States while never abdicating his role as a designer of significant projects.”

Underpinning Gyo’s pioneering design approach was a fundamental belief that each project must be approached without preconceptions and designed to serve the needs, values and aspirations of the people and community it serves. Rather than imposing his will upon a project, Gyo paid close attention to the needs expressed by clients and then let the project guide the design of a building that would bring meaning and enjoyment to its visitors and inhabitants.

“Gyo embodied everything that’s honorable about the architectural profession,” said Bill Valentine, FAIA, HOK’s chairman emeritus. “Instead of designing for the fashions of the times or to make a personal statement, Gyo designed to improve lives. He was a kind, thoughtful man who developed warm, personal relationships with his colleagues and clients. People believed in him, which is an essential part of turning drawings into buildings.”

A strong proponent of sustainable design, Gyo’s work is characterized by an efficient use of materials and sense of harmony with its natural environment. “If you see architecture as a conversation with the surrounding environment, then Gyo is the ideal conversationalist,” wrote George McCue in a 1983 cover story on Gyo for St. Louis Magazine. “The greatest virtue his buildings possess is the great ‘courtesy’ they display toward their environment.”

Gyo was an advocate for a holistic approach to design in which architecture, engineering, interior design, planning and landscape architecture are fully integrated and delivered by a single multidisciplinary design team. This approach helped drive HOK’s ongoing expansion into new specialty practices, market sectors and geographic regions.

During his 50-year tenure as HOK’s design principal, Gyo shaped iconic, award-winning projects around the world. A few noteworthy examples include the Priory Chapel at Saint Louis Abbey, Creve Coeur, Missouri (1962); The Galleria in Houston (1970); Dallas/Fort Worth International Airport (1973); Bristol-Myers Squibb Campus, Princeton, New Jersey (1973); National Air and Space Museum in Washington, D.C. (1976); King Khalid International Airport in Riyadh, Saudi Arabia (1983); King Saud University in Riyadh, Saudi Arabia (1984); Community of Christ Temple, Independence, Missouri (1994); and the Japanese American National Museum Pavilion in Los Angeles (1998).

With an approach to life that regarded each day as a portal to possibility, Gyo also loved spending time with his family and friends, gardening, tennis, art, travel, reading, his dogs, birds, music, theater, opera, films and cooking.

A Life of Design

Gyo was born in San Francisco in 1923. His parents, both artists from Japan, met in San Francisco after emigrating to the U.S. His father, Chiura Obata, introduced the classical sumi-e style of painting to the U.S. West Coast, and his mother, Haruko Obata, did the same for ikebana, the Japanese art of flower arranging. “Our house was like a studio, and was always filled with paintings and flowers,” said Gyo in the 2010 book by Marlene Ann Birkman: Gyo Obata: Architect | Clients | Reflections. “My parents were both great teachers and taught me life’s most basic lesson: to listen very carefully.”
