The Barbets owned a factory in Rouen that spun Indian cotton and wove "
indienne" cloth. It was one of the most important in the Seine-Inférieure, a center of cloth manufacture, and was awarded silver medals in 1819, 1823 and 1827. After their oldest brother left Rouen, Henri and his brother Auguste managed the Rouen factories under the name of "Barbet Frères". Later the "Barbet Frères" partnership was dissolved and Henri became sole owner of the family factory, which he expanded considerably. He and his brother-in-law Prosper Angran formed the company "Henry Barbet & Cie". He became a great industrialist. He was a member of the Rouen Commercial Court and the Chairman of the Board of the Bank of Rouen. He entered the Rouen Chamber of Commerce in 1828, and was president until 1872. In 1831 and 1833 King
Louis Philippe visited the Frères Barbet factories in Déville-lès-Rouen. Later
Napoleon III would visit the factories. In 1842 Barbet acquired the large estate of Valmont in the valley of Fécamp, including parts of the communes of
Mont-Saint-Aignan,
Canteleu,
Maromme,
Notre-Dame-de-Bondeville and
Sologne. He converted to Catholicism, and he and his wife donated two stained glass windows to the
Basilique Notre-Dame de Bonsecours. The Association pour la défense du Travail national was formed to oppose the lowering of tariffs. In 1845 it was joined by the committee of metallurgists. The council included
Antoine Odier (President),
Auguste Mimerel (Vice-President),
Joseph Périer (Treasurer) and
Louis-Martin Lebeuf (Secretary). Members included Henri Barbet,
Léon Talabot and
Eugène Schneider. Barbet became an administrator of the
Chemins de Fer du Nord. In 1858 Barbet handed over management of his factory to his son. ==Local politics==
