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.
