James Jackson (Steel Maker in France)
James Jackson (14 March 1771 - 27 April 1829) was born in Lancashire, but achieved fame in France by establishing the first crucible steel works in France, near to Saint-Étienne, in 1815. In August 1818, James Jackson left Trablaine, following a dispute with his partner, and moved to Monthieux in 1819 with his sons William, John, James and Charles, and then in 1820 to Rochetaillée and to Soleil, now Saint-Étienne. He returned to England around 1823 and died at Lancaster, Lancashire on 27 April 1829.
Jackson's sons, naturalized Frenchmen, established an important steelworks at Assailly in 1830, now in the municipality of Lorette, Loire, on the Gier river. They founded or purchased several companies that produced steel, and participated in companies that used steel as raw material.
In 1838, William Jackson married Louise Peugeot and George Peugeot married Anna Jackson. They created the company "Peugeot aîné et Jackson frères". With Pierre-Frédéric Dorian and his stepfather Jacob Holtzer, the Jackson brothers also produced scythes and sickles at Pont-Salomon. In 1859 the company took the name "Dorian, Holtzer, Jackson et Cie."
On 14 November 1854 Jackson Frères and three other companies merged and combined to form the Compagnie des Hauts-fourneaux, forges et aciéries de la Marine et des chemins de fer.
