Belden Brand Guidelines: The 1902 Chicago Magnet-Wire Maker Now Based in St. Louis

Magnet wire for telephone coils.

Belden began in Chicago in 1902, not in St. Louis, where it is based today. The International Directory of Company Histories says Joseph C. Belden, then 26 and a purchasing agent for the Kellogg Switchboard & Supply Company, struggled to find good silk-wrapped magnet wire for telephone coils and decided to make it himself. He raised start-up capital from eleven investors for the Belden Manufacturing Company and served as its president until 1939.

An early sideline in silk-wound wire frames for women’s hats did not last, the directory says, and the company found steadier markets in the new automobile and electrical appliance industries. It lists Thomas Edison and Lee De Forest, creator of the radio vacuum tube, among early customers. In 1910 Belden introduced an enamel insulation sold as Beldenamel, according to the directory; German Wikipedia dates its first success to 1905. Rubber-covered wire followed.

The First World War brought orders for wire and cable for motorized transport and field communications, and orders from England and Russia for enameled copper wire. In the 1920s commercial radio broadcasting created demand for Belden’s aerial wire, magnet wire and low-tension cables, and the company opened a second plant in Richmond, Indiana, in 1928, the directory says; German Wikipedia gives 1927.

In 1939 Belden went public on the Midwest Stock Exchange. During the Second World War, the directory says, Belden, already a major military supplier, converted much of its production to the war effort; German Wikipedia says its products went into tanks, submarines and aircraft. The period also brought new insulations in vinyl, nylon and neoprene under names such as Beldure, Nylclad and Beldfoil, and after the war the company moved into radar, sonar and electronics.

Television, Cooper and a merger.

Television and data processing drove the next phase. The directory says Belden turned toward both markets in the 1950s, renamed itself Belden Corporation in 1966 and opened new plants in Franklin, North Carolina, Pontotoc, Mississippi, and Jena, Louisiana. It built a technical research center in Geneva, Illinois, and developed Duofoil coaxial cable for master antenna and cable television systems. In 1970 its shares were listed on the New York Stock Exchange. Between 1967 and 1969 it also built a distribution arm, buying wire and parts distributors in Dallas, Detroit and San Francisco until it had 16 warehouse distribution centers, and bought General Wire & Cable of Canada with its two plants. The automotive aftermarket, which Belden had entered in 1928 and served through a 1932 agreement with the National Automotive Parts Association, grew with car sales. During the 1970s it stopped making heavy commodity wire and closed its original Chicago plant.

The following decade brought a change of owner. Facing a hostile takeover in 1980, Belden merged with Crouse-Hinds, and in 1981, when Crouse-Hinds itself became a target, Belden became a subsidiary of Cooper Industries, the directory says. Cooper spun Belden off as an independent public company in 1993, and the headquarters moved to St. Louis in 1994, according to the directory. In 1995 Belden bought Pope Cable and Wire of Venlo, in the Netherlands.

In July 2004 Belden merged with Cable Design Technologies and took the name Belden CDT Inc. German Wikipedia says the company bought two German businesses in 2007, Hirschmann Automation and Control of Neckartenzlingen and Lumberg Automation Components, and returned to the name Belden Inc. the same year. Hirschmann, which grew out of the former Richard Hirschmann GmbH, has been a Belden subsidiary since then. Further purchases listed by German Wikipedia include GarrettCom, a maker of industrial networking equipment, and the coaxial connector business of Thomas & Betts, both in 2010.

Cable as a design language.

Wire, cable and connector makers sell parts that disappear once they are installed, so their pictures tend to show the moment before that happens. Yards stacked with wooden cable drums, reels of insulated conductor and coils of copper set the scale of a cable business; close-ups of gold-plated contacts, crimped terminals and push-pull plugs show the precision of a connector maker. Bundles of colour-coded wires, laid out on a harness board, explain more about the trade than any slogan.

The customers shape the imagery. Many of these companies supply aircraft, rail vehicles, cars, factories and communications networks, and their brochures return again and again to the same scenes: a wiring harness threaded through an airframe, a connector on a train bogie, a cabinet of fibre-optic cable in a data centre. The product is rarely the hero on its own; it appears in the machine it serves.

Much of the industry’s public life happens at trade fairs. electronica, the electronics trade fair, is where component makers show connectors, sensors and assemblies to engineers and buyers, and Wire Düsseldorf gathers the makers of wire, cable and the machines that produce them. Stands are often built around cut-away samples, test rigs and walls of plugs in every size.

The names themselves reflect a long history of mergers. Several of the companies in this guide carry coined names, initials or the names of founders whose businesses were later bought and combined, and the same plug may be sold under a brand that has changed owner more than once. This guide sets out who founded each company, who owns it now and what it says about where its products are made, and marks clearly what rests only on the company’s own word.

From broadcast to networking.

Belden also spent several years in broadcast equipment. German Wikipedia says it bought the Canadian company Miranda Technologies in 2012, and Belden announced on 1 April 2014 that it had completed its acquisition of Grass Valley, the studio equipment maker. In October 2019, German Wikipedia says, Belden announced that it would leave the media technology business and separate from Grass Valley.

Its direction since then has been networking. In June 2026, in a release reposted by EMR Online, Belden, listed on the New York Stock Exchange and based in St. Louis, announced new products for operational technology networks, covering fiber infrastructure, industrial connectivity, network management and access control. On 1 July 2026 it completed its acquisition of Ruckus Networks from Vistance Networks, Cabling Installation & Maintenance reported, adding WiFi, enterprise switching and a cloud networking platform. Chief executive Ashish Chand said the purchase accelerated Belden’s change into “a full-stack networking solutions provider.”

The name has stayed constant through all of this: the founder’s surname, kept through the Cooper years, the CDT merger and the return to Belden Inc. in 2007.

For a design guide, Belden shows how a founder’s surname can carry a wire maker from telephone coils to industrial networks. Compare LAPP, the Stuttgart cable maker, and Nexans, the French cable group. For this guide we use a dark green, a soft cream and an amber with a sans, an unofficial interpretation; no product or logo is reproduced.
