Post-it Notes were invented by Spencer Silver, a scientist at 3M, in 1968 while attempting to create a super-strong adhesive. However, his creation turned out to be a weak adhesive with low sticking power. Years later, another 3M scientist named Art Fry, looking for a bookmark solution for his choir hymnal, remembered Silver’s adhesive and realized its potential.
