Schneider et Compagnie, also known as Schneider-Creusot for its birthplace in the french town of Le Creusot, was a historic French iron and steel-mill company which became a major arms manufacturer. In the 1960s, it was taken over by the Belgian Empain group and merged with it in 1969 to form Empain-Schneider, which in 1980 was renamed Schneider SA and in 1999, after much restructuring, Schneider Electric.

In 1836, Adolphe Schneider and his brother Eugène Schneider bought iron-ore mines and forges at Le Creusot (Saône-et-Loire). They developed a business dealing in steel, railways, armaments, and shipbuilding.^[3]

The Creusot steam hammer was built in 1877.

Somua, a subsidiary located near Paris, made machinery and vehicles, including the SOMUA S35 tank.

Starting in 1911, Jacques Schneider offered the Schneider Trophy. It was a competition for seaplanes, with a large and prestigious prize.
