Who invented Post-Its?

8 Apr

Romy and Michele’s High School Reunion was on TV the other day. And while I didn’t see the whole movie, I did tune in just in time to catch my favourite bit.

It’s where Romy tries to take credit for inventing Post-Its, only to have her lie brutally undone by an acerbic Heather Mooney (Janeane Garofalo), who reveals they were really created by a guy called Art Fry from 3M.

It’s a cringe inducing catch-out, and the recriminations from the popular girls Romy is trying to impress are brutal. But it did inspire me to find out his story. The answers lay in MIT’s Inventor of the Week archives.

Turns out it all began with a colleague called Spencer Silver, a senior chemist in the company’s research labs, who had created a high-quality, low-tack adhesive that was strong enough to hold papers together but weak enough to let them pull apart without tearing. He freely shared his invention with colleagues but none could come up with a marketable way to sell the product. Until it came to Art’s attention. MIT takes up the story…

“Fry sang in his church choir and was frustrated by the fact that, when he stood and opened his hymnal to sing, the paper bookmarks he used to mark the songs on the program would slip out of sight or even on to the floor. In a moment of insight that has become legendary in the realm of contemporary invention, Fry, musing during a rather boring sermon, realised Silver’s reusable adhesive would provide his bookmarks with precisely the temporary anchoring he required.”

And thus the seed was sewn, resulting five years later in the official release of Post-its.

And for the record, the reason they were first created in yellow is because the original testing/playing around was done on some scrap paper, which just happened to be yellow, and the colour struck a chord.

And now, let’s watch the magic moment …
