Renowned architect Robert A.M. Stern, a significant influence in American architecture, passed away on Thursday, as confirmed by the firm he established. He was 86 years old.

While the announcement did not mention the cause of his passing, it noted that Stern “passed away peacefully at his residence.”

The firm’s partners expressed their sorrow, stating, “At RAMSA, we mourn the loss of our founder, guide, and friend, and we are dedicated to upholding his principles.”

Stern, born in Brooklyn, New York, in 1939, launched the firm Robert A.M. Stern Architects, now known as RAMSA, in 1969. He earned distinction for his extensive career and distinctive approach, which harmonized postmodernism with contextual design, drawing from historical and traditional aesthetics.

Among his iconic works is 15 Central Park West, a luxury condominium renowned for its limestone facade, located in Manhattan adjacent to Central Park. Since its opening in 2008, the building has been home to many affluent and notable residents.

Stern’s works also include the George W. Bush Presidential Center in Dallas, the Museum of the American Revolution in Philadelphia, the Gerald R. Ford School of Public Policy at the University of Michigan and Disney’s Yacht and Beach Club Resorts in Florida.

He served as dean of the Yale School of Architecture from 1998 to 2016. He was previously the director of Columbia University’s Temple Hoyne Buell Center for the Study of American Architecture.
