&gt; No building style better represented America’s industriousness, monomaniacal greed, disregard of tradition, and eagerness to attempt feats that more established cultures considered obscene. And while those indelicate traits prompted Americans to develop the skyscraper, it was our openness and multiculturalism that brought us our greatest skyscraper builder: a Bangladeshi Muslim immigrant named Fazlur Rahman Khan.<p>What an offensive article. Highlight the characteristic (&quot;Muslim immigrant&quot;) that have nothing to do with why Khan is famous, while ragging on what was his life&#x27;s work. There is a great, possibly apocryphal, story about Khan. He was in Bangladesh and someone asked him &quot;why don&#x27;t you come back here now that you&#x27;re successful?&quot; He replied: &quot;I build skyscrapers for a living, what am I going to do here?&quot;<p>That aside, taking the Chicago architecture tour and visiting the Sears Tower is a quasi-religious experience for an engineer. This guy built a skyscraper that was the tallest in the world for more than two decades. He practiced architecture in a city where people just did stuff like that: reverse the course of a river, raise all of downtown a couple of stories, build skyscrapers with floating foundations in soft soil, hang a building from a truss because they only bought the air rights over some rail tracks, etc. You leave with the overwhelming sense that these are people who built a high-density skyscraper city in a midwestern state with cheap land as far as the eye can see just because they could.
