Ieoh Ming Pei (ˌjoʊ_mɪŋ_ˈpeɪ ; ; April 26, 1917 – May 16, 2019) was a Chinese-American architect. Raised in Shanghai, Pei drew inspiration at an early age from the garden villas at Suzhou, the traditional retreat of the scholar-gentry to which his family belonged. In 1935, he moved to the United States and enrolled in the University of Pennsylvania's architecture school, but he quickly transferred to the Massachusetts Institute of Technology. He was unhappy with the focus at both schools on Beaux-Arts architecture, and spent his free time researching emerging architects, especially Le Corbusier. After graduating, he joined the Harvard Graduate School of Design (GSD) and became a friend of the Bauhaus architects Walter Gropius and Marcel Breuer. In 1948, Pei was recruited by New York City real estate magnate William Zeckendorf, for whom he worked for seven years before establishing an independent design firm in 1955, I. M. Pei & Associates. In 1966 that became I. M. Pei & Partners, and in 1989 became Pei Cobb Freed & Partners. Pei retired from full-time practice in 1990. In his retirement, he worked as an architectural consultant primarily from his sons' architectural firm Pei Partnership Architects.
Pei's first major recognition came with the Mesa Laboratory at the National Center for Atmospheric Research in Colorado (designed in 1961, and completed in 1967). 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. He returned to China for the first time in 1975 to design a hotel at Fragrant Hills, and designed Bank of China Tower, Hong Kong, a skyscraper in Hong Kong for the Bank of China fifteen years later. In the early 1980s, Pei was the focus of controversy when he designed a glass-and-steel pyramid for the Louvre in Paris. He later returned to the world of the arts by designing the Morton H.
