Schneider-Creusot, or Schneider et Cie, was a historic French iron and steel-mill which became a major arms manufacturer. After World War II, it evolved into Schneider Electric.
In 1836 Adolphe Schneider and his brother Eugène Schneider bought iron-ore mines and forges around Le Creusot (Saône-et-Loire). They developed a business dealing in steel, railways, armaments, and shipbuilding.
The Creusot steam hammer was built in 1877.
Somua, a subsidiary located near Paris, made machinery and vehicles, including the SOMUA S35.
Starting in 1911 Jacques Schneider offered the Schneider Trophy: A competition for seaplanes, with a large and prestigious prize.
