1913, Henry Ford installs the first moving assembly line for the mass production of an entire automobile. His innovation reduced the time it took to build a car from more than 12 hours to two hours and 30 minutes.
Ford's Model T, introduced in 1908, was simple, sturdy and relatively inexpensive--but not inexpensive enough for Ford, who was determined to build "motor cars for the great multitude." ("When I'm through," he said, "about everybody will have one.") In order to lower the price of his cars, Ford figured, he would just have to find a way to build them more efficiently.
In December 1913, he unveiled the pièce de résistance: the moving-chassis assembly line.
In February 1914, he added a mechanized belt that chugged along at a speed of six feet per minute. As the pace accelerated, Ford produced more and more cars, and on June 4, 1924, the 10-millionth Model T rolled off the Highland Park assembly line.
