I.M. Pei, was born in Canton, China in 1917, immigrated to the US at age 17 and became a naturalized US citizen since in 1954. He is, quite simply, one of the most highly regarded architects on the planet. His projects are considered works of art in and of themselves.
I've been an architecture buff for many years ever since I worked as an architectural surveyor for the Metropolitan Historical Commission in Nashville between my college and law school years. So I've been a long admirer of Mr. Pei. Some of my favorite works include the Bank of China Tower, the Rock and Roll Hall of Fame, and, of course, the Louvre Pyramid.
