"Ballot was a French automobile manufacturer who made cars between 1921 and 1932.
The Ballot brothers, Edouard and Maurice, founded their company in 1905. Before the
World War I they manufactured automobile and marine engines. The company was re-founded
as Etablissements Ballot SA in 1910. Edouard Ballot was well-known as a designer of reliable
engines. He helped Ettore Bugatti in developing his first engines. After the World War I, the
company entered motor racing with a straight-eight cylinder 4.9 litre car for the 1921 French Grand
Prix. As well as racing engines, the company made a range of road engines which were fitted to their
own production cars. In 1931 the company was taken over by Hispano-Suiza." - wikipedia
