Florence in Hampshire County, Massachusetts — The American Northeast (New England)
Florence Manufacturing
The American plastics industry began in Florence in 1843 when A.P. Critchlow experimented with a new substance called the Florence Compound---a crude, brittle plastic made from resin, wood fibers and shellac from which he manufactured buttons, jewelry cases, revolver handles and its most successful product, dagosffeotype cases, By 1885, the company produced the first commercially successful toothbrush, changing its name to the Pro-Phy-Lac-Tic Brush Company in 1924. The Pro Brush Company, as it became known, diversified, manufacturing a vast array of plastic products, including Top Secret atomic bomb parts for the Manhattan Project during World War II.
Just prior to the Civil War, Leander Langdon invented and patented a sewing machine. Just five years later, the Florence Sewing Machine Company produced 20,000 sewing machines a year. By the 1870s, it was also producing stoves, becoming the Florence Machine Company. Its brick factory buildings along Florence’s Main Street now houses professional offices and shops.
