Michael Graves was the principal of Michael Graves and Associates and Michael Graves Design Group, and a member of The New York Five and the Memphis Group. He was a professor of architecture at Princeton University for nearly forty years. Following his own partial paralysis in 2003, Graves became an internationally recognized advocate of health care design. He was recognized as a major influence on architectural movements including New Urbanism, New Classical Architecture and particularly Postmodernism — the latter including the noted Portland Building in Oregon and the Humana Building in Kentucky.
