In 1968, Dr. Spencer Silver, a chemist at 3M, developed a "low-tack" adhesive that stuck lightly to surfaces and could be easily removed without leaving residue. For years, Silver promoted his invention within the company, but no one could find a practical use for it. The breakthrough came in 1974 when colleague Art Fry used the adhesive to keep bookmarks from falling out of his hymnal during choir practice. Fry realized that the sticky paper was perfect for leaving temporary notes on documents. [1]
