The Compagnie des forges et aciéries de la marine et d'Homécourt ('Company of Marine Forges and Steelworks and of Homécourt'; FAMH) was a French industrial enterprise that made iron and steel products for the French navy, army, and railroads.

[5] Starting in 1771 the Neyrand brothers became owners of several coal mines and ironworks in the valley of the Gier river.

[6] The company of Neyrand frères et Thiollière was formed in January 1845 to exploit an enlarged and modernized factory at Lorette.

He paid particular attention to the works at Saint-Chamond and Assailly, where he developed the special fabrications that brought fame to the factories.

[10] He developed arms manufacture at Saint-Chamond, and also delivered large quantities of rails to major French railroad companies.

The name was changed to Compagnie des forges et aciéries de la Marine et d'Homécourt.

[3] During World War I (1914-1918) the company built several different types of weapons, notably the Saint Chamond-Mondragón 75 mm gun which had been designed mostly by colonel Rimailho, the Saint-Chamond tank and the deficient[12] Chauchat machine rifle.

In March 1970 the latter company merged with Société des forges et ateliers du Creusot [fr] to form Creusot-Loire holding.
