Ford was launched in a converted wagon factory in 1903 with $28,000 in cash from twelve investors. During its early years, the company produced just a few Model A's a day at its factory on Mack Avenue in Detroit, Michigan. Groups of two or three men worked on each car from components made to order by other companies. Ford and his company would go on to become the first to mass produce a product using machinery and assembly lines, rather than having the same workers doing the entire assembly of one vehicle. Henry Ford was 40 years old when he founded the Ford Motor Company, which would go on to become one of the largest and most profitable companies in the world, as well as being one of the few to survive the Great Depression. The largest family-controlled company in the world, the Ford Motor Company has been in continuous family control for over 100 years.
