The discovery of Post-it sticky notes is often attributed to a 3M scientist named Spencer Silver. In 1968, Silver was attempting to develop a strong adhesive for use in aerospace applications. However, he accidentally created a low-tack, reusable adhesive that could stick to surfaces but could also be easily removed without leaving any residue.

Silver's invention did not have an immediate application, and for several years, it remained an unused technology within 3M. However, in 1974, another 3M scientist named Art Fry attended one of Silver's seminars and realized the potential of the adhesive. Fry was frustrated with his bookmarks constantly falling out of his hymnbook while singing in his church choir.

Inspired by Silver's adhesive, Fry developed the idea of using the adhesive to create sticky bookmarks. He applied the adhesive to small pieces of paper and found that they could stick to surfaces and be easily removed without damaging the pages. This led to the creation of the first Post-it notes.

After further development and testing, 3M launched Post-it notes as a product in 1980. Initially, they faced some resistance in the market, but eventually, their convenience and versatility gained popularity, making them a widely used office and household item.
