Vision by radio, radio photographs, radio photograms

In this memoir an inventive engineer traces his path from a modest farm in Indiana to a Washington laboratory where he launched the first attempts at sending photographs through radio waves. He blends personal stories with straightforward explanations of the mechanisms that turned light into a transmitted image. Listeners hear about early devices, the delicate balance of line and tone, and the excitement of picturing a world viewable at a distance.

The author also surveys the wider field of emerging visual transmission, noting how picture‑sending technology evolved alongside early motion pictures and passed through many experimental formats before settling into a practical system. He points out that ordinary infrastructure—power lines, railway rails, even water pipes—could become invisible pathways for visual data, turning everyday networks into new communication channels. By the close of the opening section, listeners feel the optimism of a time when “radio vision” seemed poised to transform science, industry, and home entertainment.
