Foucault, Jean (1819-1868) French physicist who collaborated with Fizeau in the measurement of the velocity of light using a Fizeau wheel. He invented the Foucault pendulum which demonstrates the rotation of the Earth by changing the plane of its oscillation as the earth rotated underneath it.
Lèon Foucault was a physicist from France who was most famous for his Foucault pendulum device-a delightful instrument that demonstrated the outcome of the rotation made by the Earth. He was one of the earliest scientists to attempt to measure the speed of light and he was the first to discover.
