Zündapp (aka Zuendapp) was a major German motorcycle manufacturer. The company was founded in 1917 in Nuremberg by Fritz Neumeyer, together with the Friedrich Krupp AG and the machine tool manufacturer Thiel under the name "Zünder- und Apparatebau G.m.b.H." as a producer of detonators. In 1919, as the demand for weapons parts declined after the First World War, Neumeyer became the sole proprietor of the company, and two years later he diversified into the construction of motorcycles. The company folded in 1984.
