Pierre Amidieu du Clos (16 September 1881 – 30 August 1966) was a French engineer, iron master and politician.

[2] On his father's side he was descended from the Amédée family of Florence, whose members included the founder of the Servite Order.

After the French Revolution they returned to France, where one of Pierre ancestors married Bénigne, marquise de Fontaines.

He wanted to become a lawyer, but accepted the request of his family, who owned the Forges du bassin de Briey, and studied at the École centrale des arts et manufactures, where he was a brilliant student.

He tabled many legislative proposals on subjects such as affordable housing, rents, war damage, border issues, imports and customs.

[8] In the June 1936 elections Amidieu du Clos was defeated in Briey by the Catholic lawyer George Izard, brother-in-law of Father Jean Daniélou and a member of the small Parti Frontiste.

[9] Amidieu du Clos chaired the French subsidiary of Allgemeine Elektricitäts-Gesellschaft (AEG) after World War I.

[10] After the outbreak of World War II (1939–45) Amidieu du Clos rejoined the army and was appointed a colonel.

[11] The company was founded on 19 April 1943 by a private act and was given the appearance of a French identity by its "first directors", Amidieu du Clos, Jacques Breil, Émile-Joseph Cuiller and Georges Ramat, auditor.
