Inventions That Were Obsolete When They Were Invented - Bizarre History
The radio hat was a portable radio built into a pith helmet that would bring in stations within a 20-mile (32 km) radius. It was introduced in early 1949 for $7.95 as the "Man-from-Mars Radio Hat." Thanks to a successful publicity campaign, the radio hat was sold at stores from coast to coast in the United States.
Spruce veneer bathing suits were described as simple, cheap, and easy to make, yet fashionable and modern. In a way, they were promoting the DIY (do it yourself) and recycling method of creating things. In one of the promotional videos, a girl is explaining how her father completed building a house and he had some leftover veneer. She used that veneer to make her own bathing suit. “[Wooden bathing suits] are the latest novelty for use on the bathing beaches. Fashioned of thin spruce, they are said to be practical as costumes and also are sufficiently buoyant to encourage a timid swimmer to take a plunge. So far, none of them has warped or cracked.”
What do a cat and a telephone have in common? They were the same thing in an experiment conducted in 1929 by Professor Ernest Glen Wever and his research assistant Charles William Bray here at Princeton University. Wever and Bray took an unconscious, but alive, cat and transformed it into a working telephone to test how sound is perceived by the auditory nerve.
To do so, they first sedated the cat and opened its skull to better access the auditory nerve. A telephone wire was attached to the nerve and the other end of the wire was connected to a telephone receiver. Bray would speak in the cat’s ears, while Wever would listen through the receiver 50 feet away in a soundproof room. The common notion during this time was that the frequency of the response of a sensory nerve is correlated to the intensity of the stimulus. In the case of the auditory nerve, as a sound becomes louder, the frequency or pitch of the sound received by the ear should be higher. When Bray made a sound with a certain frequency, Wever heard the sound from the receiver at the same frequency. As Bray increased the pitch of the sound, the frequency of the sound Wever heard also increased. This experiment proved that the frequency of the response in the auditory nerve is correlated to the frequency of the sound. To further validate their experiment, Wever and Bray performed more trials with varying conditions. When they placed the wire on other tissues and nerves away from the auditory nerve, the telephone receiver did not produce any sound. In one experiment, they restricted the blood circulation to the cat’s head, which also ceased the transmission of sound from the receiver. From their findings through these experiments, Wever and Bray were awarded the first Howard Crosby Warren Medal of Society by the Society of Experimental Psychologists in 1936.
