Benjamin Electric Manufacturing Company was a Des Plaines, Illinois electrical company founded in the late 19th century.
Benjamin Electric Manufacturing Company was founded by Reuben Berkley Benjamin [1] and filed its first patent for an electric lamp socket in 1898. The part was manufactured in Benjamin's basement by high school kids who worked after school. [2]
The company was officially organized in 1901 with an investment of $2,400. [3] The original founders included Walter D. Steele, Ruben B. Benjamin, and two others. It originally operated out of a small basement space, but moved to Des Plaines in 1929. [3] In 1945 it built a laboratory for testing and research, [4] and by 1948 it employed more than 1,200 people.

In 1958, Benjamin was bought out by Thomas Industries, Inc. [6] It continued to operate under the Benjamin name as a division of Thomas Industries. At the time of acquisition, it employed 600 people in two manufacturing facilities, one in Des Plaines and the other in Burlingame, California. [7]
The company's factory in Illinois was closed in 1963, with manufacturing moving to a Thomas Industries 250,000-square-foot (23,000 m2) plant in Sparta, TN. [8]
Benjamin Electric Manufacturing Company was the manufacturer of industrial and commercial lighting, floodlights, and signalling devices. [4] It pioneered a wireless cluster for lighting equipment, designed to produce higher levels of lighting from carbon filament lamps. [9] The company went on to manufacture various electrical products. One of its most notable products was a series of non-contact fire alarm horns, introduced in the early 1920s. [2] Throughout his lifetime, Reuben Benjamin secured 300 patents, most of which were used for products at the company. [10]
