André-Marie Ampère (UK: /ˈæmpɛər/, US: /ˈæmpɪər/; French: [ɑ̃dʁe maʁi ɑ̃pɛʁ]; 20 January 1775  10 June 1836) was a French physicist and mathematician who was one of the founders of the science of classical electromagnetism, which he referred to as electrodynamics. He is also the inventor of numerous applications, such as the solenoid (a term coined by him) and the electrical telegraph. As an autodidact, Ampère was a member of the French Academy of Sciences and professor at the École polytechnique and the Collège de France.

The SI unit of electric current, the ampere (A), is named after him. His name is also one of the 72 names inscribed on the Eiffel Tower. The term kinematic is the English version of his cinématique, which he constructed from the Greek κίνημα kinema ("movement, motion"), itself derived from κινεῖν kinein ("to move").
