With the success of this project, Saarinen was then invited by other major American corporations such as John Deere, IBM, and CBS to design their new headquarters or other major corporate buildings. Despite the overall rational design philosophy, the interiors usually contained dramatic sweeping staircases as well as furniture designed by Saarinen, such as the Pedestal series. In the 1950s he began to receive more commissions from American universities for campus designs and individual buildings. These include the Noyes dormitory at Vassar and Hill College House at the University of Pennsylvania as well as the Ingalls ice rink, Ezra Stiles & Morse Colleges at Yale University, the MIT Chapel and neighboring Kresge Auditorium at MIT and the University of Chicago Law School building and grounds.
