Famed New York architect Michael Graves, who also designed household goods and products for people with disabilities, has died. A spokeswoman said he passed away of natural causes Thursday at home in Princeton, New Jersey. He was 80.

His designs include The Portland Building in Oregon, The Humana Building, in Louisville, Kentucky, and the scaffolding that surrounded the Washington Monument during its renovation in the 1990s. Graves was awarded the National Medal of Arts in 1999, and the American Institute of Architects gold medal in 2001.

"Michael was ... the consummate artist," said architect and Yale professor Peter Eisenman. He and Graves were two of a group of architects known informally as the "New York Five." The group is credited with helping to redefine modernism. The other three were Charles Gwathmey, John Hejduk and Richard Meier.

"[Graves] was able to take an ordinary building and transform it through form, shape, material, light, texture. You name it," Eisenman told WNYC.
