A French polymath who made significant contributions to the fields of physics, astronomy, and mathematics, particularly in the discovery of chromatic polarization and the Biot-Savart law.

Jean-Baptiste Biot, a renowned French physicist, astronomer, and mathematician, is best known for codiscovering the Biot-Savart law of magnetostatics with Félix Savart, a fundamental concept that has had a lasting impact on the study of electricity and magnetism. Additionally, Biot made significant contributions to the fields of astronomy, mathematics, and physics, earning him a revered place in the annals of scientific history.

Born on April 21, 1774, in Paris, France, Jean-Baptiste Biot was the son of Joseph Biot, a treasury official. He received his education at the Lycée Louis-le-Grand and later at the prestigious École Polytechnique in 1794. Biot's academic prowess earned him a professorship in mathematics at Beauvais in 1797, a mere three years after completing his education.

Biot's most notable achievement is the discovery of the Biot-Savart law, which describes the magnetic field generated by an electric current. This groundbreaking work, published in 1820, has been instrumental in shaping our understanding of electromagnetism and has had far-reaching applications in fields such as electrical engineering, physics, and astronomy.

In addition to his work on magnetism, Biot made notable contributions to the study of light polarization, meteorites, and the Earth's magnetic field. His pioneering balloon flights, including the first scientific hot-air balloon ride with Joseph Louis Gay-Lussac in 1804, marked a significant milestone in the history of aeronautics.

Biot's remarkable achievements earned him numerous accolades, including election to the French Academy of Sciences in 1803, the Legion of Honour in 1814, and the Royal Society of London in 1815. He was also awarded the Rumford Medal in 1840 by the Royal Society for his outstanding work in the field of thermal or optical properties of matter.

Jean-Baptiste Biot's work has had a profound impact on modern society, influencing the development of numerous technologies, including electrical motors, generators, and transformers. His discovery of the Biot-Savart law has also paved the way for significant advances in fields such as electrical engineering, physics, and astronomy.

The CGS unit of electrical current, the mineral biotite, and Cape Biot in eastern Greenland were all named in his honor, a testament to the enduring legacy of this remarkable scientist.
