The Kellogg Switchboard and Supply Company was an influential American manufacturer founded in 1897 in Chicago, known for producing telephone equipment during the rapid expansion of the telecommunications industry. Competing with giants like Western Electric, Kellogg developed switchboards, desk telephones, and components that were widely used by independent telephone companies across the United States, especially outside the Bell System network. The company became recognized for its durable designs and distinctive styling, including early candlestick telephones and later rotary models. Kellogg remained a key player in the independent telephone market until it was eventually absorbed into larger telecommunications firms in the mid-20th century, reflecting the broader consolidation of the industry.
