Dreyse needle gun
Johann Nicolaus von Dreyse (20 November 1787 – 9 December 1867) was a German firearms inventor and manufacturer. He is most famous for submitting the Dreyse needle gun in 1836 to the Prussian army, which was adopted for service in December 1840 as the "Leichte Perkussions-Gewehr M 1841" – a name deliberately chosen to mislead about the rifle's mechanism – later renamed Zündnadelgewehr M 1841 in 1855.
