In 1935, when Le Corbusier was a guest speaker at the Massachusetts Institute of Technology, 18-year-old Ieoh Ming Pei was in the audience. Pei grew up in wealthy Hong Kong, and like many of his Chinese friends he came to America to study architecture at the University of Pennsylvania. But Penn’s Beaux Arts–centric curriculum and geriatric principles of symmetry and hierarchy bored him. If this was design, he thought, he wanted no part in it. Pei transferred to M.I.T.

As the Swiss-French eminence in rimmed glasses and a dotted bow tie talked modern architecture, Pei found himself mesmerized. Yes, Le Corbusier said, American skyscrapers are grand, but they fail to consider city planning. The Beaux Arts principles had forgotten things like the “philosophy of living.” And what about abstraction?!
