Daimler applied for a patent for the 1909 three-pointed star. The source of the Daimler logo was that he thought that the star he painted at home would bring good luck. This star symbolized the development of Mercedes-Benz in the sea, land and air. The Mercedes-Benz logo is Benz with wheat ears. In 1916, Daimler-Benz merged, the star shape and the wheat ear were merged into one, with Mercedes-Benz underneath, and the rear ear was changed to a ring and the words were removed.
