The Borchardt C-93 pistol was designed by Hugo Borchardt (1844–1921) in 1893. Ludwig Loewe & Company of Berlin, Germany, a manufacturer of machine tools, produced the C-93, a semi-automatic pistol that he had invented based upon the Maxim toggle-bolt design. Borchardt also developed the high-velocity bottlenecked 7.65×25mm Borchardt cartridge for the C-93. Borchardt's assistant at the time, Georg Luger, also claimed to have influenced its design. With over 3,000 manufactured by Loewe and Deutsche Waffen und Munitionsfabriken, Borchardt C-93 was the first mass-produced semi-automatic pistol.
