     On this vivid planet, it appears colorful with many world famous buildings. Among these largest artificial

articles in the world, many were designed by the same architect-Ieoh Ming Pei.

     Pei, the 1983 Laureate of the Pritzker, Architecture Prize, is a founding partner of I. M. Pei & Partners

based in New York City. He was born in China in 1917, the son of a banker. He came to the United States in

1935 to study architecture at the Massachusetts Institute of Technology and the Harvard Graduate School of

Design (M. Arch. 1946).

     From 1945 to 1948, Pei taught at Harvard. In 1948 he accepted the newly created post of director of

Architecture at Webb & Knapp, Inc., and this association resulted in major architectural and planning projects

outstanding projects have included the East Building of the National Gallery of Art, Washington, D.C.; the John

Humanities. He is a Fellow of the American Institute of Architects, a member of the Royal Institute of British

Architects, and an elected member of the American Academy of Arts and Letters. He is a member of the

Corporation of the Massachusetts Institute of Technology.
