History: |
Benjamin Electric Manufacturing Company was a Chicago, IL electrical company founded in the late 1800s. The company was founded by Reuben B. Benjamin, and filed its first patent for an electric lamp socket in 1898. The company went on to manufacture various other electrical products. One of Benjamin's most notable products was their series of non-contact fire alarm horns, introduced in the early 1920s. They were available in flush-mount, single, and double projector versions, in either red or gray. These horns were mainly used by IBM, and later SimplexGrinnell up until the 1960s. In 1958, Benjamin was bought out by Thomas Industries, Inc. The company's factory in Illinois was closed in 1963, and was replaced with a new 250,000 square-foot light fixture plant in Sparta, TN.
