Henry Ford revolutionized the automobile industry through innovations like the assembly line and $5 per day wages. He founded the Ford Motor Company in 1903 and began mass producing affordable Model T cars in 1908, selling over 15 million by 1927. Ford's use of the assembly line lowered costs and prices, making cars accessible to the masses. However, Ford resisted updates to the Model T and lost market share in the 1920s as competitors offered newer designs with more amenities. He remained opposed to unions as his company grew. Though a pioneering industrialist, Ford expressed anti-Semitic and authoritarian views and resisted changes in later life that diminished his modern legacy.
