Hugo Schmeisser
German firearm developer who designed the first assault rifle.
Hugo Schmeisser (24 September 1884 – 12 September 1953) was a German firearms engineer. He was born in Jena, Thuringia. His father, Louis Schmeisser (1848–1917), ranked among Europe’s most famous weapon designers. Schmeisser spent most of his career in Suhl, Thuringia, a center for arms manufacturing.
Before and during World War I, Schmeisser gained his foundational knowledge of weapons technology at Theodor Bergmann’s company, which was closely tied to early submachine gun production. There, he worked on research into 7.63 mm and 9 mm machine gun rounds. Because of his valuable expertise in machine gun technology, he remained in Suhl throughout the war.
After the Treaty of Versailles (28 June 1919) banned Germany from developing heavy machine guns but allowed submachine guns for police use, the Schmeissers’ three-decade partnership with Bergmann ended, as production was licensed abroad. Schmeisser chose to keep working on weapons. With his brother Hans, he founded “Industriewerk Auhammer Koch und Co” in Suhl. Business was slow after the war, and the treaty’s restrictions made the company’s future uncertain. Schmeisser defied the treaty by continuing to develop automatic weapons. Around this time, the firm began a 20-year collaboration with C. G. Haenel Waffen- u. Fahrradfabrik Suhl. To protect his patents, Schmeisser set up a second company, “Brothers Schmeisser,” in summer 1922—a tactic to avoid losing his patents if Auhammer went bankrupt. To stave off bankruptcy for both, Auhammer and Haenel merged, with Haenel assuming full liability. Schmeisser’s lawyers, who negotiated the deal, became active shareholders. It soon became clear that the Treaty of Versailles did not hinder—and even sped up—development of many automatic weapons. In the 1920s, Schmeisser created the MP28, widely used by German police. Bayard signed an agreement with him to manufacture and sell weapons to South Africa and Spain; these same arms saw use in the Spanish Civil War a decade later. Despite his success, the company repeatedly came close to bankruptcy.
When the Nazis rose to power in 1933, ten weapons firms in Suhl and Zella-Mehlis merged into “United Suhl-Zella Mehlis Armament Makers.” This central administration coordinated production with army needs and allowed Schmeisser to meet and befriend aviator Ernst Udet, a deputy to Hermann Göring in the Luftwaffe.

Lore & Background
Hugo Schmeisser received his fundamental training in weapons technology at Bergmann, where he worked on machine gun rounds. During World War I, he remained in Suhl due to the importance of his expertise. After the Treaty of Versailles forbade heavy machine guns, Schmeisser defied the treaty and continued developing automatic weapons. Together with his brother Hans, he created Industriewerk Auhammer Koch und Co in Suhl, later merging with C. G. Haenel, beginning a 20-year partnership. In the 1920s, he developed the MP28, used extensively by German police, and licensed production to Bayard for export.
During the Nazi era, Schmeisser became involved in a central administration of weapons enterprises in Suhl and Zella-Mehlis, and made a business acquaintance with aviator Ernst Udet. He had a direct role in military production but was not a high-level political influencer who often influenced Adolf Hitler and Hermann Göring. Contrary to popular misconception, Schmeisser did not design the MP-40 (that was Heinrich Vollmer and Berthold Geipel) and did not hold a patent on its straight magazine.
Reader's Guide
Hugo Schmeisser's significance lies in his development of the Sturmgewehr 44, one of the first assault rifles, which used a shortened 7.92 mm cartridge for resource efficiency and high production. This weapon influenced post-war infantry rifle design worldwide. Despite the popular nickname 'Schmeisser' for the MP-40, Schmeisser had no role in its development, though he held a patent on its magazine. His work at Bergmann and later at Haenel produced numerous designs, including the MP 18, MP 28, and MP 41. After the war, he was among German specialists taken to the Soviet Union, where he worked at Izhevsk. A theory that he contributed to the AK-47 is disputed by the article, which notes that the AK-47 was designed at a different factory and that German engineers were prohibited from access to classified developments. Schmeisser's legacy is that of a key technical designer whose assault rifle concept reshaped modern infantry weaponry.
