Artifact Overview
John Hays Hammond, Jr., was largely responsible for launching the field of radio control. In 1926, he built a medieval-inspired castle in Gloucester, Massachusetts. This site served as his home and research laboratory. With over 400 patents to his name, Hammond developed ideas for radio control, autopilot function, and targeted missile detonation. This device was used in Hammond's laboratory.

Airport radio navigation beacons required pilots to listen for Morse code patterns to hold the correct course--notoriously difficult during storms. In 1936, Transcontinental & Western Air introduced an anti-snow directional antenna which could be used, in high-static situations, to "home in" on airport radio signals. This loop was housed in a sleek metal enclosure, protecting it from the elements.
