In 1931, almost exactly one hundred years after Plateau, an engineering professor at the Massachusetts Institute of Technology named Harold Edgerton combined the stroboscope and the camera. He created an electronic version of the strobe in which the rotating disc was replaced by a special lamp. The lamp emits brief and rapid flashes of light. The frequency of the flash is adjusted so that it is a fraction of the object’s speed. At this point, the object appears to be stationary.
