Saarinen is now considered one of the masters of American 20th-century architecture. There has been a surge of interest in Saarinen's work in recent years, including a major exhibition and several books. This is partly because the Roche and Dinkeloo office has donated its Saarinen archives to Yale University, but also because Saarinen's oeuvre can be said to fit in with present-day concerns about pluralism of styles. He was criticized in his own time—most vociferously by Yale's Vincent Scully—for having no identifiable style; one explanation for this is that Saarinen's vision was adapted to each individual client and project, which were never exactly the same. Scully also criticized him for designing buildings that were "packages", with "no connection with human use ... at once cruelly inhuman and trivial, as if they had been designed by the Joint Chiefs of Staff".
