Benjamin Franklin Invented an Instrument So Disturbing It Was Banned

In 1761, Benjamin Franklin invented what he called the greatest of his creations — an instrument made of spinning glass bowls that played music with the touch of a fingertip. Mozart wrote for it. Marie Antoinette learned it. Thousands were built across Europe. Then, within a single generation, it vanished. Players reported tremors, melancholy, nervous collapse. Audience members fainted. A child was rumored to have died at a concert. Towns banned the instrument by police order, and the music of the armonica was silenced for nearly two centuries. Was it lead poisoning from the glass? A trick of psychoacoustics that confused the brain? Or guilt by association with a discredited Viennese doctor named Franz Mesmer? This is the documented history of the glass armonica — and the question its survivors still ask.
