Dr. F.R. Khan, the famed Bangladesh-
born engineer-architect, is the
designer of the 110-story Sears
(now Willis Tower) in
Chicago, the tallest building in the
United States. Various people have
described him as “the Einstein of
structural engineering”, “the father
of the modern skyscraper,” and “the
greatest structural engineer of the
twentieth century ”.
He is also the designer of the 100-
story John Hancock Center in Chicago
and the Hajj Terminal at the King
Abdulaziz International Airport in
Thanks to his innovative
concepts of “framed tube,” “braced
tube” and “bundled tube” structural
systems, it has now become possible
to build buildings over 100 stories.
However, not many people are
familiar with the other side of Dr.
Khan. Even though he became an
American citizen and spent almost
his entire career in the US, he
remained a ‘Bangali’ at heart all his
life. He made significant
contributions to the Liberation War
by creating public awareness in the
US and raising funds for the Bengali
refugees in India.
The avenue in front of the Willies tower is named after this famous architect- F.R. Khan Avenue.
