1873, Tribbe Daimler, then the director of Denz engine technology department, drew a three-pointed star on the postcard sent to his wife, representing his residence at that time, and made a special statement: One day, this auspicious star will shine on my life's work.
1886, Daimler and Carl Benz invented their own cars at the same time. Ben Ci designed a logo for his car-a noble laurel branch surrounded by a round logo with the word "Mercedes-Benz". When Daimler founded the company a few years later, he adopted the three-pointed star logo that he loved in his early years.
As for why it is called Mercedes-Benz, it is because:
1899 In March, Emile Jelinek (then Austrian Consul General in Hungary) drove a Demex car named after his youngest daughter Mercedes and won the first prize in the French "Nice Tour" automobile competition. He suggested that all cars produced by Daimler should be named after "Mercedes", and Daimler readily agreed. After several changes, "Mercedes-Benz" and the three-pointed star combined to form a new trademark: four small stars in the circle surround 1 big star, and the word "Mercedes-Benz" is marked below.
I hope you can accept it!
