Joseph Antoine Ferdinand Plateau (French pronunciation: [ʒozɛf ɑ̃twan fɛʁdinɑ̃ plato]; 14 October 1801 – 15 September 1883) was a Belgian physicist and mathematician. He was one of the first people to demonstrate the illusion of a moving image. To do this, he used counterrotating disks with repeating drawn images in small increments of motion on one and regularly spaced slits in the other. He called this device of 1832 the phenakistiscope.
