On the Benz side, Mercedes-Benz traces its heritage to the Benz Patent-Motorwagen—the world’s first production automobile powered by an internal-combustion engine. Karl Benz built it, but his wife, Bertha Benz, was crucial: she funded the project with her dowry and, in 1888, drove one on a historic 65-mile journey from Mannheim to Pforzheim with their sons—without telling her husband. She handled every mechanical problem along the way, proving her technical prowess.
