Page "I. M. Pei" Paragraph 1

Pei spent ten years working with New York real estate magnate William Zeckendorf before establishing his own independent design firm that eventually became Pei Cobb Freed & Partners.

Among the early projects on which Pei took the lead were the L ' Enfant Plaza Hotel in Washington, DC and the Green Building at MIT.

His first major recognition came with the National Center for Atmospheric Research in Colorado ; his new stature led to his selection as chief architect for the John F. Kennedy Library in Massachusetts.

He went on to design Dallas City Hall and the East Building of the National Gallery of Art.
