Casimir Lefaucheux obtained his first patent in 1827. In 1832, he completed a drop-barrel sporting gun with paper-cased cartridges.
Lefaucheux is credited with the invention of one of the first efficient self-contained cartridge systems in 1836, featuring a pinfire mechanism. This followed the pioneering work of Jean Samuel Pauly in 1808-1812. The Lefaucheux cartridge had a conical bullet, a cardboard powder tube, and a copper base that incorporated a primer pellet. Lefaucheux thus proposed one of the first practical breech-loading weapons.
In 1846, the Lefaucheux system was improved upon by Benjamin Houllier, who introduced an entirely metallic cartridge of copper brass.
It is thought likely that the gun with which the Dutch painter Vincent van Gogh fatally shot himself in a field in 1890 was a 7mm Lefaucheux pinfire revolver. The pistol was found, extremely corroded, in 1965 and is on display at the Van Gogh Museum in Amsterdam.
