3m Company
A diversified technology company, 3M makes everything from Post-it® notes and Command™ strips to Scotch-Brite™ abrasives, Thinsulate™ insulation, and electronic display films used in cars, data centers, and homes. It began in 1902 as the Minnesota Mining and Manufacturing Company, named for a plan to mine corundum for sandpaper that never panned out. Its Post-it notes were born from a failed attempt to make a super-strong glue, when a scientist instead created a peelable adhesive.
