John and Horace Dodge, founders of the Dodge automobile company, were brothers from Detroit, MI who got their start making bicycle parts. By 1901, they were building engines for Oldsmobile, and by 1903, they were producing most of Ford’s drive-line components. Their Ford stock made them wealthy enough to start their own company in 1914. Inseparable in life, the brothers died within months of each other in 1920. Their widows sold the company to a banker, who later sold it to Walter Chrysler.
