final jeopardy

well, the last six years of college are starting to pay off. yesterday on jeopardy, the final category was [architects]. i of course bet everything i had, answered correctly and doubled my fake money. the other three contestants, however, all got it wrong. so i pose the question to anyone out there that reads this. [what architect stated that he introduced the glass box, and then 50 years later, broke it] no cheating and remember to answer in the form of a question.
