In 1931, New York's Empire State Building became the tallest building in the world and a symbol of America's place on the world stage after World War II.
Few expected, however, that at 381 metres (1,250 feet) high, it would remain the world's tallest for more than four decades. After it was completed, the Great Depression hit, followed by World War II and postwar austerity.
Skyscrapers, for all their bombast, were seen as massively inefficient, and anything bigger taller than the Empire State Building was inherently dangerous: the sheer amount of steel required to keep it upright was hardly worth the investment.
That was before Fazlur Rahman Khan came along. A Bangladeshi-born engineer who moved to America, Khan's "tube" design opened the door for a new generation of skyscrapers that could be built safely and efficiently. His designs have been behind the world's tallest buildings since the World Trade Center in 1972.
On Monday April 3, Google has commemorated what would have been Khan's 88th birthday with a Doodle showing Chicago's famous John Hancock Center, one of his most famous designs.
It would be a fortuitous destination, for Chicago is now known for two of Khan's famous buildings. While he was working at an architectural firm in the city, there was growing concern about where people would live amid urbanisation and a population explosion, but skyscraper designs like the Empire Trade Building, which required huge steel reinforcements to keep them stable, were seen as inefficient.
The first of Khan's designs to use the idea was the DeWitt-Chestnut building in Chicago, then Chicago's famous John Hancock Center in 1968. At the time it was the world's second tallest building after the Empire State, and was much more efficient to build, using 145kg of steel per square metre compared to the Empire State Building's 206kg. The tube structure is neatly demonstrated by the John Hancock Center's visible exterior frame.
Although it wasn't Khan's design, the tube structure was used in the World Trade Center, which broke the Empire State Building's 41-year streak as the world's tallest building when it was completed in 1972.
It remained the tallest structure in the United States until One World Trade Center in 2014, although it was renamed the Willis Tower in 2009.
Khan died in 1982 but his tube structure is still used when making skyscrapers, including those that replaced the Sears Tower as the world's biggest.
Kuala Lumpur's Petronas Towers, Taipei's Taipei 101 and Dubai's Burj Khalifa all use a version of the tube structure.
When the Burj Khalifa was completed in 2010, The Telegraph called it "the ultimate expression of his audacious, lightweight design philosophy" and said he had "changed both the economics and the morphology of supertall buildings".
He was also mentioned by Barack Obama in 2009 as an example of Muslims' contributions to America.

Fazlur Rahman Khan (Bengali: ফজলুর রহমান খান, Fozlur Rôhman Khan) was a Bangladeshi-American structural engineer and architect who initiated important structural systems for skyscrapers. Considered the "father of tubular designs" for high-rises, Khan was also a pioneer in computer-aided design (CAD). He was the designer of the Sears Tower (now Willis Tower), the tallest building in the world until 1998, and the 100-story John Hancock Center.Khan, more than any other individual, ushered in a renaissance in skyscraper construction during the second half of the 20th century. 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 construction. The Council on Tall Buildings and Urban Habitat established the Fazlur R. Khan lifetime achievement medal in his honor.
Although 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.
