Ambi Budd was a company founded by Edward Gowen Budd in Philadelphia, USA. Budd studied at the University of Pennsylvania and his first work was at a company making automobile wheels from pressed steel rather than by casting. Steel-shaping technology progressed rapidly at the time and soon the company also made parts like doors and front walls in pressed steel. In 1912, Budd started his own company after he found out how to make complex shaped parts in pressed steel. The company's chief engineer was Joseph Ledwinka, a relative of Hans Ledwinka. The company managed to land several large orders like an all-steel body for Buick and 2000 Oakland superstructures. Later Budd also made bodies for Cadillac, Chrysler, Delage, Citroën, Mercedes, Morris and Nash as well as the doors of the Ford Model T. In 1916 Budd also started the Budd Wheel Company making wheels for Dodge. In 1935 they made ventilated disc brakes, first for racing, but later also for passenger cars.
Due to the high demand of parts for Ford Model T and A, the company started another factory in Detroit in 1925.
In 1925, William Morris visited the Budd factory and when he returned home he started the Pressed Steel Company in Coventry. In Germany, Budd worked with Arthur Müller and set up a steel pressing plant as "ABP" (Ambi Budd Presswerke) in the old Rumpler factory and became a successful supplier of pressed-steel components. Budd owned 26% of the Adler stock and were located next door to the German assembly plant for Chrysler. Budd also supplied bodies for early BMWs as well as German Fords. In 1943, the company had to move production underground due to bomb attacks from the allied air forces. They also made parts for the Focke Wulf fighters. They also made bodies for the Volkswagen Kübelwagen and Schwimmwagen'. The Berlin plants were completely destroyed by bombing during WW2. After the war, the Budd plant ended up in the Soviet sector. The machines and tools were dismantled and most of them shipped to the Soviet Union. In the USA, Budd made shell and bomb casings and helmets during the war.
