| biography:
| Physicist and astronomer, born in Paris, France. Professor of physics at the Collège de France, he made a balloon ascent with Joseph Louis Gay-Lussac to study magnetism at high altitudes in 1804. He invented a polariscope and established the fundamental laws of the rotation of the plane of polarization of light by optically active substances. In 1820 he collaborated with Félix Savart to demonstrate the relationship between an electric current and the magnetic field it produces (the Biot–Savart law). |
