Schwarzmüller was founded in 1870 by Joseph Schwarzmüller as a blacksmith's shop in Passau, Germany. In 1921, the first trailer left the factory, then still with wooden wheels fitted with rubber tires. In 1936, Joseph Schwarzmüller Jr. moved the company to Austria. Since then, it has grown steadily and become an international supplier of commercial vehicles, which is still owned by the family that founded it.
