William (Bill) Hellmuth, FAIA, the chairman and CEO of HOK, passed away on April 6, 2023, after a long illness.
An extraordinary architect and leader, Hellmuth designed dozens of award-winning buildings across the globe and, as president and later chairman and CEO of HOK, raised HOK’s profile within the design community and beyond. During his leadership, HOK was listed as one of the world’s most influential companies by Time Magazine, repeatedly earned mention in Fast Company’s list of most innovative companies and was annually ranked the world’s largest design firm specializing in both architecture and engineering.
While proud of HOK’s accomplishments, Hellmuth kept his focus on the future and was happiest while brainstorming ideas with clients and HOK project teams. He was elected president of HOK, Inc. in 2005. When tapped to become CEO in 2016, Hellmuth accepted the role on the condition that he could remain the design principal for HOK’s Washington, D.C., studio and firm-wide design leader. A year later, he also was named chairman.
Susan Klumpp Williams, managing principal of the D.C. office, worked alongside Hellmuth for more than 30 years. She recalls how he would impress clients with his commitment to their projects even while overseeing the firm’s global strategies and operations.
“They never expected him to be so hands-on. But that is something Bill took great pride in,” said Klumpp Williams. “He was happiest when working with one of our designers at their desk. His passion for design and our profession inspired those of us who had the privilege of working closely with him.”
A few of Hellmuth’s most notable designs include the 75-story Abu Dhabi National Oil Company Headquarters in the UAE; the U.S. Embassy Chancery and Office Annex in Moscow; the U.S. Embassy in Nairobi; the Sheraton Inn Timika Guest House in Irian Jaya, Indonesia; Msheireb Downtown Doha mixed-use community in Qatar; King Abdullah Petroleum Studies and Research Center and Residential Community in Riyadh, Saudi Arabia; Rhine Ordnance Barracks Medical Center Replacement in Kaiserslautern, Germany; the U.S. Environmental Protection Agency Headquarters in Research Triangle Park, North Carolina; Morgan State University’s Jenkins Hall Behavioral and Social Sciences Center in Baltimore; and the Hampton Roads Convention Center in Hampton, Virginia.
