Citroën, a major French automobile manufacturer, officially celebrated its 90th anniversary. The company, which was founded by French industrialist André-Gustave Citroën in 1919, has contributed a number of key innovative technologies to the automotive world over the decades. One example was the Traction Avant automobile, which Citroën introduced in 1934. This vehicle was the first mass-produced front-wheel automobile; it was also one of the first automobiles to feature a unitary body rather than a chassis to hold all the mechanical components together. Another one of the company’s pioneering vehicles was the Citroën DS, which made its debut in 1955. This vehicle was the first mass-produced automobile with modern disc brakes.
