In his writings, he always offered explanations that went beyond the visual and attempted to frame architectural forms within a theoretical corpus. Always careful not to tread on intellectual territories that were foreign to the architects' aim, he nevertheless opened up ambitious references that could serve to relate specific works with major trends in the global discussion. Because this is what David was, above all: a living example of a cultural bridge, a connector of ideas, people, and works. Always keen to discuss at the highest level, was a friend and mentor in several ways. And he will, already is, deeply missed.
David B. Stewart was born in Washington, D.C., in 1942. He pursued his education at the University of Pennsylvania, where he earned a Bachelor of Arts with honors in the History of Art (1960–1964), and later at the Courtauld Institute of Art at the University of London, where he completed his PhD in the History of European Art under the supervision of Professor Sir Nikolaus Pevsner (1964–1972), with a thesis about Le Corbusier. Before moving to Japan, he was a member of the editorial staff of L’Architecture d'aujourd'hui in Paris.
He taught the history of architecture at the famed Tokyo Institute of Technology (now Science Tokyo) since 1976, where he was nominated Specially Appointed Professor in his last years. His articles appeared in many international magazines and he lectured extensively worldwide, with some of his lessons available on YouTube. He is survived by his wife and two sons.
