The greatest designs of modern times: Post-it Notes Designed by 3M (Spencer Silver + Arthur Fry), 1977 The majority of the great designs on this list began as solutions to problems. But the Post-it began life as a solution without a problem. In the late 1960s, 3M chemist Spencer Silver—in pursuit of a superstrong adhesive—accidentally created a low-tack, reusable adhesive that could hold two surfaces together but easily be pulled apart. After kicking around the company for a few years, Silver’s colleague Arthur Fry used the adhesive for the bookmark in his hymnal so stop it falling out, sparking the idea for the Post-It. And the iconic yellow of the paper that eventually became home to that new substance? Also an accident. It was the color of the scrap paper available to the design team.
