Pierre-Louis-Adrien de Montgolfier-Verpilleux (6 November 1831 – 23 January 1913) was a French engineer who became a representative of the Loire in the National Assembly, and then a senator.

In the last half of his life he was responsible for a major iron and steel company, making heavy armaments and railway tracks.

[2] In 1856 he was appointed engineer to the department of the Loire with responsibility for building flood-control dams in the valleys of the rivers Furens and Gier.

[2] Montgolfier was elected representative of the Loire in the French National Assembly on 8 February 1870, while still confined in Besançon.

Riots broke out at Saint Etienne in which the prefect of the Loire, M. de l'Espée, died on 25 March 1871.

[2] On 27 March 1871 Montgolfier was sent as the government's extraordinary commissioner to restore peace, with full civil and military powers.

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.

[10] In 1908 Montgolfier was forced by illness to give up the general directorship, although he continued to live in Saint-Chamond and to take an interest in the company's affairs.
