Pierre-François-Marie Olivier de Vezin

François Pierre Olivier de Vézin, a young ironmaster from Champagne, France, was only 28 years old when the Ministre de la Marine (i.e., The royal secretary for the navy and overseas colonies) sent him to the site to determine whether or not Francheville's experiment should be pursued. Vézin confirmed that the project was viable provided that another process for reducing iron ore be used. Vézin was then put in charge of erecting a full-scale ironworks.

After overcoming a long series of technical problems, Vézin finally blew in the blast furnace on August 20, 1738. The following year, an additional forge was built, thus rounding off a complex of workshops it had taken Vézin three years to construct and which were to last for close to 150 years.
