Karl Benz patented his first Motorwagen in 1885. Meanwhile Gottlieb Daimler was working with Nikolaus Otto in Cologne for Deutz engine company and attempted to patent a new four-stroke cycle, but were denied by Karl Benz's own two-stroke design. Daimler Motoren Gesellschaft was founded in 1890. In Austria Emil Jellinek bought several Daimler cars for his own use, and then placed orders for resale and demanded faster vehicles. He began to race Daimler cars branding them 'Mercedes' after his own daughter, and then commissioned development of a new engine that would be branded 'DMG-Mercedes'. Maybach's design for the 1900 35hp 'Mercedes' racer caused a stir, and laid the format for future car design; it also beat everything else at the Paris-Nice event. 'Mercedes' was then registered as the brand for Daimler vehicles. In 1924 the difficult market conditions following the end of the First World War pushed DMG and Benz into cooperation and partnership and in 1926 Daimler-Benz was formed. Maybach went into the manufacture of his own cars from 1921 to 1941 although the main business was aero engines.
