Gottlieb Wilhelm Daimler (German: [ˈɡɔtliːp ˈdaɪmlɐ]; 17 March 1834 – 6 March 1900) was a German engineer, industrial designer and industrialist born in Schorndorf (Kingdom of Württemberg, a federal state of the German Confederation), in what is now Germany. He was a pioneer of internal-combustion engines and automobile development. He invented the high-speed liquid petroleum-fueled engine.
Daimler and his lifelong business partner Wilhelm Maybach were two inventors whose goal was to create small, high-speed engines to be mounted in any kind of locomotion device. In 1883 they designed a horizontal cylinder layout compressed charge liquid petroleum engine that fulfilled Daimler's desire for a high speed engine which could be throttled, making it useful in transportation applications. This engine was called Daimler's Dream.
In 1885 they designed a vertical cylinder version of this engine which they subsequently fitted to a two-wheeler, the first internal combustion motorcycle which was named the Petroleum Reitwagen (Riding Car) and, in the next year, to a coach, and a boat. Daimler called this engine the grandfather clock engine (Standuhr) because of its resemblance to a large pendulum clock.
In 1890, they converted their partnership into a stock company Daimler Motoren Gesellschaft (DMG, in English – the Daimler Motors Corporation). They sold their first automobile in 1892. Daimler fell ill and took a break from the business. Upon his return he experienced difficulty with the other stockholders that led to his resignation in 1893. This was reversed in 1894. Maybach resigned at the same time, and also returned. Daimler died in 1900 and Wilhelm Maybach quit DMG in 1907.
Daimler is seen as "the father of the motorcycle".
