Wilhelm Mauser, German engineer and businessman, co-founded the Mauser Company (born 1834)

Wilhelm Mauser was a German weapon designer and manufacturer/industrialist.

Mauser, originally the Königlich Württembergische Gewehrfabrik, was a German arms manufacturer. Their line of bolt-action rifles and semi-automatic pistols was produced beginning in the 1870s for the German armed forces. In the late 19th and early 20th centuries, Mauser designs were also exported and licensed to many countries, which adopted them as military and civilian sporting firearms. The Gewehr 98 in particular was widely adopted and copied, becoming one of the most copied firearms designs and it is the foundation of many of today's sporting bolt-action rifles. Around 10 million Gewehr 98 style rifles were produced.
