Ieoh Ming Pei (b. April 26, 1917), commonly known by his initials I. M. Pei, is a Pritzker Prize-winning Chinese American architect, known as the last master of high modernist architecture. He works with the abstract form, using stone, concrete, glass, and steel. Pei is perhaps one of the most successful Asian architects of the 20th century, with his works built all over the world.

In 1948, William Zeckendorf hired Pei to work at the real estate development corporation Webb and Knapp in a newly created post, Director of Architecture. While at Webb and Knapp, Pei worked on many large-scale architectural and planning projects across the country and designed his buildings mostly in the manner of Ludwig Mies van der Rohe. Pei founded his own architectural firm in 1955, which was originally known as I. M. Pei and Associates and, later, I. M. Pei & Partners until 1989 when it became known as Pei Cobb Freed & Partners recognizing James Ingo Freed and Henry N. Cobb. (www.wikipedia.org)
