3M was founded in 1902 in the town of Two Harbors, Minn., when five businessmen agreed to mine a mineral deposit for grinding-wheel abrasives. But the deposits proved to be of little value, and the new Minnesota Mining and Manufacturing Co. (3M) moved to nearby Duluth, Minn., in 1905 to focus on sandpaper products.
Years of struggle ensued until the company could master quality production. New investors were attracted and the company moved to St. Paul in 1910. Early technical and marketing innovations began to produce successes and, the company paid its first dividend of 6 cents a share in 1916.
- The world's first waterproof sandpaper, which reduced airborne dusts during automotive manufacturing, was developed in the early 1920s.
- A second major milestone occurred in 1925 when Richard G. Drew, a young lab assistant, invented masking tape an innovative step toward diversification and the first of many Scotch® brand Pressure-Sensitive Tapes.
- In the following years, technical progress resulted in Scotch® Cellophane Tape for box sealing, and soon hundreds of practical uses were discovered.
- In the early 1940s, 3M operations were diverted into defense materials for World War II, which was followed by new ventures, such as ScotchliteTM Reflective Sheeting for highway markings, magnetic sound recording tape, filament adhesive tape and the start of 3M's involvement in the graphic arts with offset printing plates.
- In the 1950s, 3M introduced the Thermo-FaxTM Copying Process, ScotchgardTM Fabric Protector, videotape, Scotch-Brite® Cleaning Pads and several new electro-mechanical products.
- Dry-silver microfilm was introduced in the 1960s, along with photographic products, carbonless papers, overhead projection systems and a rapidly growing health care business of medical and dental products.
- Markets further expanded in the 1970s and 1980s into pharmaceuticals, radiology, energy control, office products and globally to almost every country in the world.
- In 1980, 3M introduced Post-it® Notes, which created a whole new category in the marketplace and changed people's communication and organization behavior forever.
- In the 1990s, sales reached the $15 billion mark. 3M continued to develop an array of innovative products, including immune response modifier pharmaceuticals; brightness enhancement films for electronic displays; and flexible circuits used in inkjet printers, cell phones and other electronic devices.
- In the 1990s, 3MTM Privacy Plus Filter (first computer screen accessory to combine privacy, glare reduction and radiation protection); the world’s first CFC-free inhaler for asthma sufferers and structured abrasives (using 3M's proprietary microreplication technology) are launched.
- In 2004, sales topped $20 billion for the first time, with innovative new products contributing significantly to growth. Recent innovations include Post-it® Super Sticky Notes, Scotch® Transparent Duct Tape, optical films for LCD televisions and a new family of Scotch-Brite® Cleaning Products that give consumers the right scrubbing power for a host of cleaning jobs.
