Toussaint-Henry-Joseph Fafchamps
Joseph Montigny further improved the weapon, completing the transportable 37-barrels Montigny mitrailleuse (also known as the "Fafschamps-Montigny mitrailleuse") in 1863. From 1859, Joseph Montigny proposed his design to Napoleon III, which led to the development of the French Reffye mitrailleuse, designed by Jean-Baptiste Verchère de Reffye with the collaboration of Montigny, and which was adopted by the French Army in 1865. The invention of Fafschamps thus became the basis of the "mitrailleuse", which was used by the French in the Franco-Prussian War of 1870. Initially kept under wraps as a secret weapon, it became widely used in battle by French artillery during the Franco-Prussian War (1870–71).
Girandoni air rifle
The Girandoni air rifle was an airgun designed by Tyrolian inventor Bartholomäus Girandoni circa 1779. The weapon was also known as the "Windbüchse" ("wind rifle" in German). One of the rifle's more famous associations is its use on the Lewis and Clark Expedition to explore and map the western part of North America in the early 1800s.
