Inventor of Post-It Notes Adhesive Dies at 80-years-old

The inventor of Post It Notes adhesive passed away at 80-years-old. According to the Associated Press, the Post-It Note is the company, 3M's, best-known product. It's also now the best-selling product in 3M's consumer products division. According to the AP, and Spencer Silver's obituary, he died May 8th at his home. 

In 1968, Silver was working in the laboratory when he discovered an unusual adhesive formula. The adhesive allowed Post-It Notes to easily stick to surfaces, and be reposted, without leaving a residue. 

Spencer Silver's co-worker came up with the idea of using the adhesive to prevent the paper notes from falling out of his hymnal. 

Silver retired in 1996. He earned 37 patents at 3M. Silver also won several awards, including the 1998 American Chemical Society Award for Creative Invention. 

Rest in Peace Spencer Silver.
