Overview
Chicago Radio Laboratory was the original company that later became Zenith Radio Corporation. Founded in 1918 in Chicago, Illinois, the company initially produced amateur radio equipment and radio receivers during the early growth of wireless communications in the United States.
The business was established by Karl Hassel and Ralph H. G. Mathews, both amateur radio operators. The company name originated from its early laboratory-style operations focused on radio experimentation and manufacturing.
Chicago Radio Laboratory became known for producing high-quality radio equipment during the early 1920s. The company later adopted the Zenith name in 1923, derived from the amateur radio call sign “9ZN,” which was associated with the founders.
After becoming Zenith Radio Corporation, the company expanded into one of the largest and most recognized American manufacturers of radios, televisions, and consumer electronics during the 20th century.
