Hubbell Incorporated was founded as a proprietorship in 1888 by Harvey Hubbell II. Born in Connecticut in 1859, he was a U.S. inventor, entrepreneur and industrialist. His best-known inventions are the U.S. electrical plug and the pull-chain light socket. He graduated from high school and began working for companies that manufactured marine engines and printing machinery. During this time, he accumulated several ideas for new inventions, and in 1888 he set out on his own, opening a small manufacturing facility in Bridgeport, Connecticut. Hubbell's first product was taken from his own patent for a paper roll holder with a toothed blade for use in stores that sold wrapping paper. This cutter stand became a tremendous success; it was a common feature of retail stores that used wrapping paper in the early 1900s and remained in wide use into the late 20th century.
