Mr. Pei, who was born in China and moved to the United States in the 1930s, was hired by William Zeckendorf in 1948, shortly after he received his graduate degree in architecture from Harvard, to oversee the design of buildings produced by Zeckendorf’s firm, Webb & Knapp.

Architect I.M. Pei, whose work transformed the built environment in cities around the world and was widely celebrated by fellow architects, has died. He was 102.
