The Maserati brothers, Alfieri (1887–1932), Bindo (1883–1980), Carlo (1881–1910), Ettore (1894–1990), and Ernesto (1898–1975), were all involved with automobiles from the beginning of the 20th century. Alfieri, Bindo, and Ernesto built 2-litre Grand Prix cars for Diatto. In 1926, Diatto suspended the production of race cars, leading to the creation of the first Maserati and the founding of the Maserati marque. One of the first Maseratis, driven by Alfieri, won the 1926 Targa Florio. Maserati began making race cars with 4, 6, 8, and 16 cylinders (two straight-eights mounted parallel to one another).   The trident logo of the Maserati car company, designed by Mario Maserati, is based on the Fountain of Neptune in Bologna's Piazza Maggiore. In 1920, one of the Maserati brothers used this symbol in the logo at the suggestion of family friend Marquis Diego de Sterlich. It was considered particularly appropriate for the sports car company due to the fact that Neptune represents strength and vigour; additionally the statue is a characteristic symbol of the company's original home city.
