César Pelli was an Argentine-American architect who designed some of the world’s tallest buildings and other major urban landmarks. Two of his most notable buildings are the Petronas Towers in Kuala Lumpur and the World Financial Center in New York City. As a draftsman, Pelli gifted friends with scrawls depicting his world’s tallest buildings. The Petronas Towers in Kuala Lumpur, Malaysia were the highest buildings until being surpassed in 2004 by Taipei 101.
