Zenith had plants all over Chicago, and its shutdown was a major loss to the Chicago area. In addition to the Galewood complex, Zenith had a picture tube plant at Montrose and the Kennedy Expressway (Rauland) as well as another facility on North Avenue in Melrose Park, and what I believe was a distribution center on Northwest Avenue in Northlake along I-294. Zenith also had a hearing aid factory on Grand, I believe at the corner of Natoma Avenue, just south of the present Brickyard shopping center. The west/northwest side was loaded with radio manufacturers, with Motorola occupying an Art Moderne building at 4545 W. Augusta Avenue, and Admiral Corporation had a complex just south and east of Armitage and Pulaski. Webcor, Majestic, and others were all strung along the Milwaukee Road right of way also. Interestingly, my dad told me that Majestic actually started as a "battery eliminator" company, building transformers that would power a battery operated radio, in the 4300 block of Armitage Avenue. The current strip mall was actually a block of old store fronts which was moved to the back of the property to accommodate parking. My dad worked there probably in the early to mid 1920's.
