Post-It Notes - An Unintentional Discovery


The invention of the humble Post-It Note was an accidental collaboration between second-rate science and a frustrated church-goer. In 1970, Spencer Silver, a researcher for the large American corporation 3M, had been trying to formulate a strong adhesive, but ended up only managing to create a very weak glue that could be removed almost effortlessly. He promoted hisinvention within 3M, but nobody took any notice.

4 years later, Arthur Fry, a 3M colleague and member of his church choir, was irritated by the fact that the slips of paper he placed in his hymnal to mark the pages would usually fall out when the book was opened. One service, he recalled the work of Spencer Silver, leading to an epiphany – the church being a good a place as any to have one, I suppose – and later applied some of Silver’s weak yet non-damaging adhesive to his bookmarks. He foundthat the little sticky markers worked perfectly, and sold the idea to 3M. Trial marketing began in 1977, and today you’d find it hard to imagine life without them.
