Cemented In History

The Egyptians, the Romans, and modern-day architects have all used concrete in their construction from some of the most basic of structures, to the most magnificent buildings in world history.  But one inventor, someone who is widely known for his other inventions, tried to revolutionize how we see and use concrete forever.  His attempts were valiant, but the concrete future never reached the heights that he had envisioned.  His one shining moment in this venture, though, is one of the most historic and famous stadiums of all time.  Find out who this inventor is and what stadium he created on this episode of The Missing Chapter.
