“Dwelling narrowly on the legacy of designers gives the impression that architectural history concerns great men, not great places,” writes Lance Hosey in the Huffington Post. Hosey was commenting on an essay that I wrote recently in Architect, in which I speculated about what might have happened if certain celebrated unbuilt projects had actually been realized. It is fashionable to think that architecture is not the creation of great men—or great women—but is it true? Does anyone really believe that the spirit of Louis Kahn did not manifest itself in his designs? When he died, that spirit died with him. When Eero Saarinen died, Kevin Roche and John Dinkeloo continued the practice, but Saarinen’s mercurial creativity was absent. The art of building is a peculiar art that relies on team work—in that sense it resembles film-making rather than novel-writing. But as in film-making, the auteur is often present. I remember working for Moshe Safdie in the 1970s. There were a dozen or so people in the office, but when Safdie was away, a certain inertia set in as people waited for him to return and make decisions. The decisions might concern alternatives developed by someone else, but there was never any doubt about who would have the final word.
