The museum at Sochaux stands alongside the huge car plant of PSA Peugeot-Citroën, the largest in France. It tells the complex story of the development of the family business since the brothers Jean-Pierre and Jean-Frédédic Peugeot adapted an old corn mill as a foundry and forge in 1810. The foundry side of the concern soon proved unprofitable, but the brothers diversified into making springs for clocks, and gradually developed rolling mills and other facilities for shaping metal. They manufactured household appliances, such as coffee grinders and sewing machines as well as machine tools. In the second half of the nineteenth century the company turned to making bicycles, and then to motor cycles, and the first Peugeot motor car appeared in 1891.
The museum has comprehensive displays of Peugeot products, including bicycles that were ridden by winners of the Tour de France, racing cars and concept cars. Visitors can gain an understanding of how a small local metalworking business became a global motor car company. The project to establish a museum was launched in 1982 at the instigation of Pierre Peugeot (1932-2002), and it is located in a building that was once part of the factory. It includes the company archives. Tours of the factory can be arranged in association with visits to the museum.
