How it Happened: A church choir is to thank for Post-it Notes

By Gail Marsh
Chances are you have some in your desk drawer right now. Or perhaps there’s one on your refrigerator reminding you of needed grocery items. Post-it Notes are so common that it’s hard to envision a time without them. But this accidental invention was originally “a solution without a problem,” according to its inventor, Dr. Spenser Silver.

A sticky invention

Dr. Silver, a scientist at 3M laboratories in the late 1960s, was charged with the task of finding a super strong adhesive. “We wanted to develop bigger, stronger, tougher adhesives. This was none of these.” Instead, Silver invented an adhesive that could attach with very little pressure, hold, and then be removed without leaving behind any residue. Dr. Silver tried for years to figure out a use for his sticky invention but was unsuccessful.

Church choir practice?

If you had to guess how Dr. Silver’s adhesive finally gained popularity, you would probably never guess that it was a church choir practice that provided the impetus to bring Dr. Silver’s adhesive to the public. You see, another 3M scientist, Art Fry, sang in his church choir. Each Wednesday, at choir practice, Fry dutifully marked hymns that the choir planned to sing on the following Sunday. He put a scrap of paper at the appropriate places in his hymnal to help him locate the songs to be sung. The problem was that by the time Sunday came, all of Fry’s “bookmarks” had fallen out and the hymns were no longer marked. What Fry needed was a paper that would not fall out. He needed a paper that would stick to the hymn book’s pages, but not leave behind any kind of residue.

A Post-it Notes collaboration

Then Art Fry remembered Dr. Silver’s sticky invention—the solution without a problem. Could it be that Fry had identified a problem for Silver’s invention to solve? Soon Fry and Silver partnered together and developed much more than a paper bookmark! They gave prototypes of their invention to all of the 3M employees, and everybody loved them!


First launched as “Press ‘n Peel” notes, the cheery yellow adhesive notes were eventually marketed as we know them today: Post-it® Notes!

Bonus: Why the canary yellow color? The only scrap paper in the lab at the time was yellow. Now, of course, the famous sticky notes come in a variety of colors.

Do you carry Post-it Notes in your RV as you travel? How do you use them? Tell us in the comments, please.

Thank you, Gail. This sort of “how it began” story is always intetesting, but this one is exceptional. I used post-it notes to mark citations when writing my dissertation. DW, a commercial real estate attorney, wrote deadlines for documents, meetings, whatever on post-it notes. All the various steps necessary for her clients to buy or sell something were on post-it notes and affixed to oversize calendars in her office. Each deal was given its own color so she could easily distinguish them from each other. Thankfully, she never had more than 3 or 4 deals at a time and never ran out of colors. 🙂

Have them in the house, in the car, and in the RV. Many uses…

I keep them in our RV to use for trip directions — a kind of short-hand for map instructions, I suppose. A few quick notes, route numbers, town names, etc and then stick ’em on the dashboard where I can easily see them, then remove when done. “You have reached your destination!” Not that I don’t trust GPS directions… but I don’t trust GPS directions. Gimme a paper map.

I would not make it without “Stickies” aka Post-Its. Interestingly, our biggest use for them is marking the pages in our hymnal for the Sunday worship songs! But our current night time reading book gets its Post-It page marker, too. I especially like them for my ToDo list so I can categorize, prioritize, and re-order at will. I try to limit my list to what will fit on a single 8.5 x 11 sheet of paper, but I stretch the number of items by cutting each Post-It to fit the item description thereby defeating my purpose! Oh well.

We had them in our RV while we were still working, but not in retirement.
