Joseph Montigny Joseph Montigny was a Belgian gunsmith, from Fontaine l'Evèque near Brussels, and the developer of the Montigny mitrailleuse, an early European machine gun, in 1863. The design was based on the early 1850s prototype of a volley gun by the Belgian officer Fafschamps. Montigny managed to offer his design to Napoléon III, who adopted it in 1867, with Colonel De Reffye making various improvements to the weapons.
