Fazlur Rahman Khan

Also known as the "father of tubular designs" for high-rise structures, Fazlur Rahman Khan is credited with being one of the first modern architects to use computer-aided designs, or CAD. One of the best engineers of the 20th century unquestionably, Khan's ideas can be seen in contemporary skyscrapers all around the world, even those he wasn't personally involved with, like the original World Trade Center in New York.

Khan, who was born in 1929 in Dhaka, Bangladesh, began working for the eminent Chicago architectural firm Skidmore, Owings & Merrill in 1955. In the latter half of the 20th century, his tubular designs—particularly the "bundled tube" structural system, which reduced the amount of construction material needed—led to a type of revolution in skyscraper architecture. The John Hancock Center in Chicago, the Haj Terminal at the King Abdul Aziz International Airport in Jeddah, Saudi Arabia, and other notable structures are among Fazlur Rahman Khan's best-known creations.
