An assembly line is a manufacturing process in which individual parts of a larger product are put together in a specific order. Today this process is usually performed by computers, but in its early days it required human hands. The assembly line sped up the manufacturing process dramatically. It allowed factories to churn out products at a remarkable rate, and it also managed to reduce labor hours-benefiting many workers who used to spend 10 to 12 hours a day in the factory trying to meet quotas. The Ford Motor Company adopted the assembly line between 1908 and 1915, and it helped the company become a significant force in the United States economy.On this day in 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.
