Jean Bernard Léon Foucault was a French physicist in the 19th century best known for experiments demonstrating the rotation of the Earth, most famously through a swinging pendulum (the Foucault pendulum). His work provided crucial evidence for understanding planetary motion and made fundamental contributions to the study of light and optics.

He also made an early measurement of the speed of light, discovered eddy currents, and is credited with naming the gyroscope.
