This company succeeded the firm of H. Lecouteux, founded in 1840.
In 1860 it specialised in steam engines and developed considerably in 1873, when Corliss engines were first introduced into France. The following types of engines were built at La Courneuve - Corliss engines, engines with valves of the Lentz type, equicurrent engines, Rateau, steam turbines, centrifugal pumps, ventilators, and compressors. The firm had also undertaken to work the patents held by the Societe de Nuremberg for single and double-acting gas engines in France, and acquired the rights for France of the Guldner motors working on the Diesel cycle, allowing the use of cheap oils and petrols. The firm also made refrigerating machines, and turbo-refrigerators on the Monteil system.
