Serendipity at 3M: In the late 1960s, Spencer Silver worked at 3M Company, producing adhesives. While trying to develop a super-strong glue, Silver accidentally created one that stuck poorly. Unable to envision any practical use for it, he discarded it after discovering its ineffectiveness.
Years later, in 1974, 3M scientist (Serendipity at 3M) Art Fry became frustrated with his bookmarks falling out of his hymnal while singing in church choir. Recalling Silver’s weak adhesive, Fry realized it could be useful for creating bookmarks without damaging pages of his hymnal. So he applied Silver’s weak adhesive onto paper and used it as a bookmark – successfully adhering it in place but weak enough to remove without damaging the page.
Fry noticed the potential of this weak adhesive, especially for creating removable notes that wouldn’t leave behind sticky residue. He and Silver collaborated to perfect their formula and created what would later become known as Post-it Notes – products designed with precision adhesive technology for maximum adhesion without leaving behind sticky residue.
Post-it Notes were first released in 1980 and quickly achieved worldwide fame. Spencer Silver’s accidental discovery of weak adhesive, coupled with Art Fry’s application of it (Serendipity at 3M), revolutionized how people take notes and organize their lives – a prime example of how innovation can come from unexpected places and mistakes lead to amazing discoveries.
Art Fry used the weak adhesive as a bookmark and quickly realized its potential uses, particularly in office settings. He shared this vision with colleagues but they initially were skeptical; however, once they saw how easy it could be to leave reminders and notes on documents, they began to appreciate its worth.
However, the initial launch of Post-it Notes wasn’t particularly successful. 3M had difficulty marketing the product and convincing customers to try it out, so eventually they began giving out free samples in an effort to gain momentum.
Post-it Notes’ success led to the birth of an entire industry of adhesive notes and related products. Nowadays, there are numerous companies manufacturing similar items; however, Post-it Notes remain the most well-known and beloved brand worldwide.
Spencer Silver, the inventor of weak adhesive, never made a fortune from his invention. He continued working at 3M (Serendipity at 3M) until 1996 and received several awards for it, including induction into the National Inventors Hall of Fame. Despite not benefitting directly from it, Silver was immensely proud of his role in developing Post-it Notes and their positive effects on people’s lives.
