The Battle Over the Invention of the Sticky Note: Who Really Created It?
In modern offices and study rooms, sticky notes — small, colorful squares that hold reminders, ideas, and to-dos — have become a universal essential.
Compact, convenient, and instantly adhesive, they’re symbols of creativity and productivity.
Yet few people realize that behind this seemingly simple piece of paper lies a decades-long dispute over who truly invented it.
1. The 3M Scientists: From “Failed Glue” to a World-Changing Idea
The story, according to U.S. industrial giant 3M, begins in 1968.
Scientist Spencer Silver developed a unique adhesive — not too strong, not too weak — that could stick and unstick repeatedly without leaving residue.
At first, it was considered a failed experiment. No one could find a commercial use for it.
Years later, Arthur Fry, another 3M employee, faced a small but annoying problem in his church choir:
the bookmarks he used to mark hymns kept falling out.
Then came the spark of genius — what if Silver’s “weak adhesive” could be applied to paper to make repositionable bookmarks?
That simple idea gave birth to what would later be known as the sticky note.
By 1977, 3M had begun limited sales, and by 1980, Post-it Notes were officially launched across the U.S.
They quickly became one of 3M’s most iconic products — a symbol of accidental innovation that reshaped the global office culture.
2. The Independent Inventor: Alan Amron and the Gum-Stick Inspiration
But not everyone agrees with 3M’s version of history.
Alan Amron, an American inventor, insists that he is the true father of the sticky note — claiming he invented it in 1973, a year earlier than 3M’s official timeline.
Amron, known for creative products such as the electric water gun and digital photo frame, holds 39 U.S. patents.
He told the Associated Press that the idea struck him while trying to leave notes for his wife on the refrigerator.
He used chewing gum to stick paper to the fridge — and suddenly realized,
“If paper itself could have a gentle, reusable adhesive, it would be perfect.”
Amron said he built a prototype and displayed it at a trade show in New York,
where he met two 3M executives — but no deal was made.
A few years later, 3M released the Post-it Note, remarkably similar to his concept.
Ever since, Amron has maintained that he was the original inventor.
3. From Courtrooms to Settlements: A 20-Year Tug-of-War
In 1997, Amron sued 3M in court, seeking formal recognition as the true inventor.
The two parties later reached a confidential settlement, the details of which were never made public.
According to Amron, the agreement stated that neither party would publicly claim to be the sole inventor.
However, nearly two decades later, the dispute reignited.
Amron accused 3M of breaching the settlement by continuing to promote the Post-it Note
as an invention of Fry and Silver alone.
He demanded $400 million in damages and insisted 3M publicly acknowledge his contribution.
“I just want them to admit that I’m the inventor,” Amron said.
“As long as they keep denying it, they’re damaging my reputation.”
3M, on the other hand, firmly rejected his claim:
“The invention of the Post-it Note did not involve Alan Amron in any way,”
the company said, maintaining that Fry and Silver were the sole inventors.
The court encouraged both sides to reach another settlement before the end of the year —
but the debate over this tiny piece of paper still hasn’t been put to rest.
4. Beyond the Invention: Innovation Lives On
Regardless of who first came up with the idea,
the sticky note remains one of the most ingenious products of the modern era —
a reminder that sometimes great inventions are born from small problems.
And today, decades after its creation, this little piece of paper has found new life around the world.
In Dongguan, China, a city known for precision manufacturing and creativity,
Dongguan Boyi Printing Co., Ltd. has become a renowned producer of custom sticky notes,
continuing the legacy of innovation that the Post-it began.
