The motor car was developed over many years by a number of talented individuals but Karl Benz of Mannheim in Germany is normally credited as the inventor of the motor car. In the autumn of 1885, his three-wheeled vehicle became the first successful petrol-engined car. He was awarded a patent for it on 29 January 1886 and became the first motor manufacturer in 1888 with his Modell 3 Benz. In 1886, Gottlieb Daimler and his protégé Wilhelm Maybach built the first successful four-wheeled petrol-driven car at Bad Cannstatt. The Daimler Motoren Gesellschaft was established four years later in 1890. On 1 July 1926 Benz and Daimler merged to become Daimler-Benz AG and its products Mercedes-Benz. Fredrick William Bremer, a plumber and gas fitter, built the first British four-wheeled petrol-engined motor car. Starting work in 1892, when he was 20, the still incomplete car made its first run on a public highway in December 1894.
