![]() ![]() During the 1960s and 1970s, he became noted for his designs for Chicago's 100-story John Hancock Center and 110-story Sears Tower, since renamed Willis Tower, the tallest building in the world from 1973 until 1998. His first building to employ the tube structure was the Chestnut De-Witt apartment building. Khan introduced design methods and concepts for efficient use of material in building architecture. He worked the rest of his life side by side with fellow architect Bruce Graham. In 1955, employed by the architectural firm Skidmore, Owings & Merrill (SOM), he began working in Chicago. Career Ī sculpture honoring Fazlur Khan at the Willis Tower He found that a hollow tube, like the bamboo in Dhaka, lent a high-rise vertical durability. Despite this, the environment of his hometown in Dhaka later influenced his tube building concept, which was inspired by the bamboo that sprouted around Dhaka. He did not view his first skyscraper in person until the age of 21 years old, and he had not stepped inside a mid-rise building until he moved to the United States for graduate school. His hometown in Dhaka did not have any buildings taller than three stories. In three years Khan earned two master's degrees – one in structural engineering and one in theoretical and applied mechanics – and a PhD in structural engineering with thesis titled Analytical Study of Relations Among Various Design Criteria for Rectangular Prestressed Concrete Beams. There he studied at the University of Illinois at Urbana–Champaign. He received a Fulbright Scholarship and a government scholarship, which enabled him to travel to the United States in 1952. After that, he studied Civil Engineering in Bengal Engineering and Science University, Shibpur (present day Indian Institute of Engineering Science and Technology, Shibpur), Kolkata, India, and then received his Bachelor of Civil Engineering degree from Ahsanullah Engineering College (now Bangladesh University of Engineering and Technology). ![]() Khan attended Armanitola Government High School, in Dhaka. Khan's paternal uncle, Abdul Hakim Khan, was the son-in-law of Syed Abdul Jabbar, a zamindar based in Comilla. His mother, Khadijah Khatun, was the daughter of Abdul Basit Chowdhury, the Zamindar (aristocratic landowner) of Dulai in Pabna who traced his ancestry to a migrant from Samarkand in Turkestan. ![]() His father, Khan Bahadur Abdur Rahman Khan, was a high school mathematics teacher and textbook author who eventually became the Director of Public Instruction in Bengal and after retirement served as the first Principal of Jagannath College. He was from and brought up in the Khan Bari of Bhandarikandi in Madaripur, Faridpur District. Family and background įazlur Rahman Khan was born on 3 April 1929 to a Bengali Muslim family in Dhaka, Bengal Presidency (present-day Bangladesh). In his honor, the Council on Tall Buildings and Urban Habitat established the Fazlur Khan Lifetime Achievement Medal, as one of their CTBUH Skyscraper Awards.Īlthough best known for skyscrapers, Khan was also an active designer of other kinds of structures, including the Hajj airport terminal, the McMath–Pierce solar telescope and several stadium structures. ![]() He has been called the "Einstein of structural engineering" and the "Greatest Structural Engineer of the 20th Century" for his innovative use of structural systems that remain fundamental to modern skyscraper design and construction. He was the designer of the Sears Tower, since renamed Willis Tower, the tallest building in the world from 1973 until 1998, and the 100-story John Hancock Center.Ī partner in the firm Skidmore, Owings & Merrill in Chicago, Khan, more than any other individual, ushered in a renaissance in skyscraper construction during the second half of the 20th century. Considered the "father of tubular designs" for high-rises, Khan was also a pioneer in computer-aided design (CAD).
