World-renowned architect Ieoh Ming (I.M.) Pei is celebrating his 99th birthday today.

The Pyramid at the Louvre in Paris.

He was born in Guangzhou, China, in 1917 and eventually moved to New York to study architecture. He established his first architectural firm in 1955.

The glass-happy Pei became famous for designing the Bank of China Building in Hong Kong and the Pyramid at the Louvre in Paris.

His most prominent buildings in the United States include the Four Seasons Hotel on 57th Street in New York, the John F. Kennedy Library in Boston, the National Gallery of Art’s East Building in Washington and the Rock and Roll Hall of Fame in Cleveland.
