Short Summary
André-Marie Ampère was a pioneering French physicist and mathematician, renowned for his groundbreaking work in electromagnetism. He is best known for formulating Ampère's law, which describes the magnetic force between two electrical currents. His contributions laid the foundation for the science of electrodynamics, and he is considered one of the founders of the field of classical electromagnetism. Ampère's name is immortalized in the ampere, the unit of electric current in the International System of Units.
Early Life & Education
Born on January 20, 1775, in Lyon, France, André-Marie Ampère was the son of Jean-Jacques Ampère, a prosperous businessman, and Jeanne Antoinette Desutières-Sarcey Ampère. His father encouraged his passion for learning, and despite the turmoil of the French Revolution, Ampère pursued his education at home. He was a child prodigy with an early interest in mathematics, and by the age of 13, he had mastered differential calculus. Ampère's education was largely self-directed, enabling him to explore various scientific disciplines, which later influenced his multifaceted career.
Career Highlights
Ampère's career began with a position as a mathematics teacher in Lyon in 1802, followed by a professorship at the École Polytechnique in Paris in 1809. In 1820, inspired by Hans Christian Ørsted's discovery of electromagnetism, he conducted his own experiments leading to the formulation of Ampère's law. He also held a position at the Collège de France, where he continued his research and teaching. His work in electrodynamics solidified his status as a leading scientist of his time, and his contributions extended beyond physics to include chemistry and philosophy.
