About the Photos

Our holdings include hundreds of glass and film negatives/transparencies that we've scanned ourselves; in addition, many other photos on this site were extracted from reference images (high-resolution tiffs) in the Library of Congress research archive. (To query the database click here.) They are adjusted, restored and reworked by your webmaster in accordance with his aesthetic sensibilities before being downsized and turned into the jpegs you see here. All of these images (including "derivative works") are protected by copyright laws of the United States and other jurisdictions and may not be sold, reproduced or otherwise used for commercial purposes without permission.

Neutrodyne Tweaker: 1924

Neutrodyne Tweaker: 1924

July 1924. "A new use for discarded automobile horns has been discovered by Dr. William C. Fowler, health officer of Washington, D.C. Dr. Fowler has adapted an old rams-horn type auto horn, a relic of the days when they blew them with bulbs, and fitted it to his radio to serve as a loudspeaker. This gives as good a tone as any he could buy, he says." This photo of Dr. Fowler tuning a Freed-Eisemann Neutrodyne receiver clears up the minor mystery of who this is. Harris & Ewing Collection glass negative. View full size.

 

Honk if you hear this

Those horn speakers were sold retail by radio companies like Westinghouse/RCA (called the Vocarola) and by others.
