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). Piazza Maggiore\'s Neptune and his trident 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.[8] Alfieri Maserati died in 1932, but three other brothers, Bindo, Ernesto, and Ettore kept the firm going. Orsi ownership In 1937, the remaining Maserati brothers sold their shares in the company to the Adolfo Orsi family, who, in 1940, relocated the company headquarters to their home town of Modena,[4] where it remains to this day. The brothers continued in engineering roles with the company. Racing successes continued, even against the giants of German racing, Auto Union and Mercedes. In back-to-back wins in 1939 and 1940, an 8CTF won the Indianapolis 500, making Maserati the only Italian manufacturer ever to do so.[9] The second world war then intervened and Maserati abandoned car making to produce components for the Italian war effort. During this time, Maserati worked in fierce competition to construct a V16 town car for Benito Mussolini before Ferry Porsche of Volkswagen built one for Adolf Hitler. This failed, and the plans were scrapped. Once peace was restored, Maserati returned to making cars; the A6 series did well in the post-war racing scene. Juan-Manuel Fangio driving a Maserati 250F Key people joined the Maserati team. Alberto Massimino, a former FIAT engineer with both Alfa Romeo and Ferrari experience, oversaw the design of all racing models for the next ten years. With him joined engineers Giulio Alfieri, Vittorio Bellentani, and Gioacchino Colombo. The focus was on the best engines and chassis to succeed in car racing. These new projects saw the last contributions of the Maserati brothers, who, after their 10-year contract with Orsi expired, went on to form O.S.C.A. This new team at Maserati worked on several projects: the 4CLT, the A6 series, the 8CLT, and, pivotally for the future success of the company, the A6GCS. The famous Argentinian grand prix driver Juan-Manuel Fangio raced for Maserati for a number of years in the 1950s, achieving a number of stunning victories including winning the world championship in 1957 in the 250F. Other racing projects in the 1950s were the 200S, 300S, 350S, and 450S, followed in 1961 by the famous Tipo 61.
