So, why didn't I think of that? When Art Fry did invent an adhesive-backed note card in 1974 and created the ubiquitous Post-it Note, it took more than just a little ingenuity. It took chemical know-how and some major backing from his employer 3M. "We realized that what we had was not just a bookmark," says Fry, "but a new way to communicate or organize information." Hear Art Fry explain how and why in a podcast created by the Smithsonian's Lemelson Center for the Study of Invention and Innovation. What's your favorite thing you do with Post-it Notes?
