The Phenakistoscope
Brief History.
In 1832, Belgian physicist Joseph Plateau and his sons introduced the phenakistoscope ("spindle viewer"). It was also invented
independently in the same year by Simon von Stampfer of Vienna, Austria, who called his invention a stroboscope. Plateau's
inspiration had come primarily from the work of Michael Faraday and Peter Mark Roget (the compiler of Roget's Thesaurus). Faraday
had invented a device he called "Michael Faraday's Wheel," that consisted of two discs that spun in opposite directions from
each other. From this, Plateau took another step, adapting Faraday's wheel into a toy he later named the phenakistoscope.
