May 27, 1930 — patent for Scotch Tape received
Richard Gurley Drew, the inventor of Scotch tape, received a patent for his invention on May 27, 1930.
Why called “Scotch” tape? It’s because, when Drew was first testing the tape with customers and it didn’t adhere properly, the customers told him, “Take this tape back to those Scotch bosses of yours and tell them to put more adhesive on it.
The “bosses” were at 3M, the company that started manufacturing Drew’s invention and continues to do so to this day.
