The origins of Mercedes-Benz can be traced back to Karl Benz's invention of the first petrol-powered car, the Benz Patent Motorwagen, patented in January 1886, and Gottlieb Daimler and engineer Wilhelm Maybach's conversion of a stagecoach by the addition of a petrol engine later that year. In 1926, Daimler-Motoren-Gesellschaft (DMG) and Benz & Cie. merged to form Daimler-Benz, which would later become Mercedes-Benz. The brand name "Mercedes" derives from a 1901 line of cars by DMG powered by the Daimler-Mercedes engine, which was developed by Maybach and named after the daughter of Emil Jellinek, an Austrian automobile entrepreneur who worked with DMG. The merger of the companies led to the creation of the Mercedes-Benz brand, symbolized by the three-pointed star logo that represents the brand's ambition of universal motorization on land, water, and air.
