The Chicago Faucet Company, founded on the near-west side of Chicago, Illinois, United States, has been producing faucets and other plumbing fixtures since 1901. The company founder, Albert C. Brown, invented the Quaturn Cartridge in 1913 that worked with the flow of water to make it both easy to open and close the spigots and forestalled leak development. In 2002 the Swiss Geberit AG acquired Chicago Faucet. Currently the Chicago Faucet Company has its headquarters in Des Plaines, Illinois, and employs over 200 people in Des Plaines, Milwaukee, Elyria, Ohio, and Michigan City, Indiana.
