Physics

André-Marie Ampère


André-Marie Ampère (1775-1836) was a French physicist, philosopher, scientist, and mathematician who made important contributions to the study of electromagnetism.

He was born in Poleymieux, near Lyon, France in 1775. He was Professor of Analysis at the Polytechnic School of Paris and the Collège de France. In 1814 he was elected a member of the Academy of Sciences. He occupied himself with various branches of human knowledge, leaving important works, especially in the field of physics and mathematics.

Based on the experiments of Danish Hans Christian Oersted on the magnetic effect of electric current, he was able to structure and create the theory that made possible the construction of a large number of electromagnetic devices. In addition, he discovered the laws governing the attractions and repulsions of electric currents among themselves. He devised the galvanometer, invented the first electric telegraph, and, in collaboration with Arago, the electromagnet.

Among his works, he left unfinished Essay on the philosophy of science, in which he began to classify the knowledge of man. Posted Recueil d'Observations électro-dynamiques; La theorie des phénomènes électro-dynamiques; Prerequisites of Theory of Phenomenes Electro-dynamics; Considerations on the theory of mathematics of the jeu; Essai sur la philosophie des sciences.

In his honor, the name of ampere (symbol: A) was given to the unit of measurement of the intensity of electric current.

André-Marie Ampère died on June 10, 1836, in Marseilles, France, at the age of fifty-two and is buried in the Cimetiere de Montmartre, Paris.
