Léon Foucault (born September 18, 1819, Paris, France—died February 11, 1868, Paris) was a French physicist whose “ Foucault pendulum ” provided experimental proof that Earth rotates on its axis. He also introduced and helped develop a technique of measuring the absolute speed of light with extreme accuracy.

About the Authors. Léon Foucault's name is synonymous with his famous pendulum experiment, which proved for the first time that the Earth rotated. However, his contributions to science went well beyond his pendulum - the gyroscope; laboratory measurements of the speed of light; the invention of methods to make perfect optical surfaces which ...
