John Francis Dodge was born on October 25, 1864, while his brother Horace Elgin Dodge arrived four years later, on May 17, 1868. The brothers grew up in Michigan and began their careers as machinists. In 1897, they co-founded a bicycle company; however, by 1900, they had sold the business and opened a machine shop in Detroit to make parts for the fledgling auto industry. In 1901, Ransom Olds hired the Dodges to produce engines for his new curved-dash Oldsmobile vehicles. Next, Henry Ford contracted with the brothers to build engines, transmissions and axles. Ford was unable to pay the Dodges fully in cash, so he gave them stock in his company. (In 1919, the brothers sold their Ford Motor Company stock back to Henry Ford for $25 million.)
