author
1880–1948
An engineer-turned-popular science writer, he explained radio, electronics, and atomic theory in a way ordinary readers could actually enjoy. His books turn big technical ideas into clear, lively conversation.

by John Mills
Born in 1880 and active as an engineer in the Engineering Department of Western Electric Company, he wrote practical, accessible books at a time when radio and modern physics were transforming everyday life.
His best-known works include Letters of a Radio-Engineer to His Son (1922), along with Radio-Communication, The Realities of Modern Science, Within the Atom, and Electronics; Today and Tomorrow. Across these books, he had a gift for making complicated subjects feel approachable without talking down to the reader.
Library and catalog records identify him as John Mills (1880–1948). Reliable biographical detail beyond his engineering work and published books is limited in the sources I could confirm, but his writing clearly aimed to help general readers understand the science shaping the modern world.
