40 Strange Historical Facts That You Didn’t Learn In History Class
The cat phone
Cats are smart little animals and we love them dearly. We’ve always known they had immense potential for world domination, but this little tidbit was surprising even to us. In 1929, researchers at Princeton turned a live cat into a functioning telephone, but fair warning before you read on, it was not humane. Ernest Wever and Charles Bray removed a portion of a live cat’s skull as well as most of its brain and attached an electrode to its right auditory nerve. They attached another electrode to the cat’s body. Both electrodes were hooked up to an amplifier, and the signals were sent to a telephone receiver. When they talked into the cat’s ear, Wever and Bray could hear the sound in the receiver. This awful experiment was believed to be the inspiration for the eventual invention of cochlear implants.
