He built the iPhone:
Apple was suddenly demanding massive amounts of a 1.3-mm, chemically strengthened glass—something that had never been created, much less manufactured, before. Could Chemcor, which had never been mass-produced, be married to a process that would yield such scale? Could a glass tailored for applications like car windshields be made ultrathin and still retain its strength? Would the chemical strengthening process even work effectively on such a glass? No one knew. So Weeks did what any CEO with a penchant for risk-taking would do. He said yes.
One of the things I am consistently amazed by is how interesting seemingly uninteresting businesses are once you dig into them. One would think that in 2012 glass would be pretty boring, but this is a fantastic piece in Wired on the making of Gorilla Glass, the now ubiquitous material that makes iPhones and other smart devices possible.
