Dan Kiley, 91; Landscape Architect Worked on Major U.S. Landmarks

Dan Kiley, 91, who garnered praise around the world for his work in landscape architecture, died Feb. 21 at his home in Charlotte, Vt. The cause of death was not announced, but he had been in declining health .

Kiley’s body of work is extensive. He had landmark commissions for the John F. Kennedy Library in Boston, parts of the Air Force Academy in Colorado and the East Wing of the National Gallery in Washington, D.C., and was the architect for the conversion of the Nuremberg Palace of Justice into courtrooms for the Nazi war crime trials after World War II.

He worked with some of the world’s finest architects, including I.M. Pei, Philip Johnson and Louis Kahn.

“Kiley is the best,” Pei said in a 1997 interview. “He’s not just limited to doing a small house or gardens. He also has tremendous scope and breadth in his thinking about landscape. He treats landscape with grand gestures.”

Born in Boston, Kiley studied at the Harvard graduate school of design before starting his architecture firm in Washington, D.C., in 1940. He served in the Army during World War II. He designed the Nuremberg courtrooms while a member of the Office of Strategic Services.

After the war, Kiley moved first to New Hampshire and then to Vermont, where he lived for the rest of his life.
