Despite the name, Scotch tape wasn't invented by the Scottish. It was invented by a college dropout named Richard Drew from Minnesota who worked for a small sandpaper company founded in 1902 called Minnesota Mining and Manufacturing, later known as 3M.

Born Richard Gurley Drew in St. Paul, Minnesota in 1899, Drew spent a year at the University of Minnesota in the Mechanical Engineering program before dropping out.
