Wax nostalgic about and learn from the history of early electronics. See articles from Popular Science, published 1872-2021. All copyrights hereby acknowledged.

From the 194s through the 1980s, National Radio Institute (NRI) ran full-page and multi-page advertisements in many electronics and technology magazines, including Popular Mechanics, Radio News, and here in this 1947 issue of Popular Science. I don't recall exactly how/where I learned of the NRI when I enrolled in their "Electronic Design Technology" course, circa 1987. At the time I was working as an electronics technician for Simmonds Precision Instruments in Vergennes, Vermont. That was immediately preceding my completing a Bachelor of Science degree in Electrical Engineering at the University of Vermont. My formal training in electronics began in the U.S. Air Force while attending technical school at Keesler AFB, Mississippi, for being an Air Traffic Control Radar Repairman. NRI president J. E. (James Ernest) Smith, whose face appeared regularly in the ads, was born in 1881, at the dawn of electronics, and passed away in 1973.
