Kellogg Switchboard & Supply Company
Kellogg Switchboard & Supply Company was an American manufacturer of telecommunication equipment. Anticipating the expiration of the earliest, fundamental Bell System patents, Milo G. Kellogg, an electrical engineer, founded the company in 1897 in Chicago under the laws of the state of Illinois to produce telephone exchange switching equipment and telephone apparatus.
Along with Western Electric, which supplied the Bell System, Automatic Electric supplying General Telephone, and Stromberg-Carlson, also supplying the independent telephone markets, Kellogg shared in the business of providing the bulk of the nation's telephone equipment until after World War II.
Milo G. Kellogg was born into a prominent and wealthy New England family. He attended prep school, and received two degrees in engineering from the University of Rochester. He married a member of one of Chicago's most prestigious families, and relocated to Illinois.
In the 1880s, Kellogg was a manager at Western Electric as superintendent of its Chicago manufacturing and research plant, and also at the Southern Telephone and Telegraph Company. In 1897, with Alexander Graham Bell's patent for the telephone expiring, Kellogg set up a manufacturing firm, the Kellogg Switchboard & Supply Company. Kellogg himself held more than 150 patents, and had invented and the divided multiple telephone switchboard, which became the flagship product of the new company. This switchboard offered greater flexibility and efficiency than earlier designs in handling a large telephone subscriber base at urban exchanges. Kellogg primarily supplied local independent telephone companies.
Fight for control
In 1901, Kellogg fell seriously ill. His brother-in-law, Wallace DeWolf, proved to be a poor manager. Concerned that the company might fail, DeWolf secretly sold a majority of Kellogg's stock to Western Electric. Easily manipulated by Western Electric executives and legal advisors, DeWolf also helped Western Electric attempt to take over the country's other large telephone equipment manufacturer, Stromberg-Carlson. A bitter stockholder fight ensued, which led to Stromberg-Carlson's reincorporation as a New York state corporation in 1902.
Milo Kellogg recovered his health, and discovered what DeWolf had done. Kellogg sued to stop the sale of his stock. In two separate decisions by the Supreme Court of Illinois—Brown v. Cragg, 230 Ill. 299 (1907) and Dunbar v. American Telephone and Telegraph, 238 Ill. 456 (1909)—Kellogg retained ownership of his company.
In 1903, the Kellogg Switchboard & Supply Company was the target of a bitter strike by the Brass Molder's Union Local 83 and the International Brotherhood of Teamsters. Kellogg Switchboard & Supply was supported by the Bell Telephone Trust (which at the time owned most of Kellogg Switchboard's stock), the Illinois Manufacturers' Association, and the Employers' Association of Chicago. Kellogg Switchboard sued to stop the Teamsters from engaging in their sympathy strike, and won an injunction forcing the drivers back to work. The Kellogg company refused to negotiate, fired nearly 90 percent of its workforce, and broke the strike.
The ITT Corporation purchased a controlling interest in the Kellogg Switchboard & Supply Company in 1951, rebranding the new division's equipment as ITT Kellogg for a decade. It then became ITT Telecommunications, but reverted to ITT Kellogg in 1986. Among ITT Kellogg's acquisitions in the 1950s was telephone manufacturer Federal Telephone & Radio.
In 1989, ITT sold its telecommunications product lines, including ITT Kellogg, to Alcatel, now Alcatel-Lucent. The company's U.S. operations were later sold and privatized. The remaining business of Kellogg is conducted by Cortelco Kellogg, owned by Cortelco (Corinth Telecommunications Corporation) and is based in Corinth, Mississippi.
On December 12, 2008 eOn Communications announced an agreement to acquire Cortelco Systems Holding Corporation.
