One of the few Americans to focus on processes was Henry Ford. Born in Michigan in 1863 Ford began an apprenticeship as a machinist at the age of 16, and in 1891 he was hired as an engineer for the Edison Illuminating Company. Five years later, he constructed his first model of a horseless carriage, which he called the Ford Quadricycle. In 1903, Henry Ford started the Ford Motor Company, and soon began selling the Model A.
But Ford’s legacy was less in automobile design, and more in his manufacturing processes. Between his assembly line, which allowed cars to be assembled quickly with standardized parts, and his decision to add small amounts of vanadium to his steel, which made the steel production process much easier (not to mention resulted in stronger and more durable steel), Ford revolutionized the way that cars were produced, allowing them to be produced quickly and cheaply – which in turn allowed them to be sold in large numbers at a low price.
