Internet entrepreneur Jay Walker used his fortune to create an elaborate library filled with intellectual achievements spanning human history, including a copy of Sputnik, the napkin that Roosevelt sketched out his plan for victory in 1943, and a field tool kit for Civil War surgeons. Walker describes his motivation:
"I started an R&D lab and have been an entrepreneur. So I have a big affinity for the human imagination," he says. "About a dozen years ago, my collection got so big that I said, 'It's time to build a room, a library, that would be about human imagination.'"
