There are two inspiring and oft-repeated stories that you may not have been aware of if not ignored or forgotten. First case: In 1973, church choir member Arthur Fry, then a new product researcher at 3M, had a major concern. To mark the pages of his hymnal books, he used ordinary pieces of paper that would normally fly out of the pages or fell out altogether during rehearsals and live performances.
He thought he could try sampling a new adhesive that was being experimented by 3M scientist Spencer Silver, who was then looking for its practical use and marketability. Fry got a sample of the new adhesive from Silver and used it in several pieces of paper to mark the pages of his choir books. Eureka! It was strong enough to cling on paper without damaging it when removed. And that’s how the Post-It Note was born.
