Here's the story:
* Emil Jellinek was a passionate supporter of the Daimler-Motoren-Gesellschaft (DMG), a German automobile manufacturer.
* He was particularly impressed with the company's powerful engines and wanted to promote their cars.
* In 1900, Jellinek entered a DMG car in the Nice Race, using the pseudonym "Mercedes" for his daughter.
* He won the race and, impressed by the car's performance and the success it garnered, decided to use the name "Mercedes" for all future DMG cars.
* In 1902, the "Mercedes" trademark was officially registered.
So, while the car itself wasn't actually named after his daughter, the name "Mercedes" became synonymous with the high-quality and performance of DMG's cars. It quickly gained recognition and became a symbol of luxury and engineering excellence.
