Inventors
Henry Ford and the Moving Assembly Line – Lesson
He invented a process that made the car accessible to average Americans.
Henry Ford is often credited with inventing the automobile, but, in reality, Ford invented a process called the moving assembly line, which helped transition automobiles from a luxury good to a product that middle-class Americans could afford. He used the method to mass-produce his Model T vehicle, revolutionizing transportation in a way that changed the world forever.
Ford Invents Moving Assembly Line
After building the Quadricycle – a gasoline-powered vehicle – Ford started the Ford Motor Company on June 16, 1903. Just five years later, the company revealed the Model T, a revolutionary vehicle that “became so popular at one point that a majority of Americans owned one,” according to History.com.
Formerly an employee of the Edison Illuminating Company of Detroit, Ford used his engineering background to develop the world’s first moving assembly line, which used conveyor belts to move parts to workers, who would then assemble each section of a Model T. Ford devised the process after observing “continuous-flow production” in breweries, flour mills, and meatpacking plants.
Ford’s invention significantly improved production speed, reducing the time it took to build one Model T from nearly half a day to just over 90 minutes. “When I’m through, about everybody will have one,” Ford said.
‘Tin Lizzie’
Ford’s Model T is often referred to as a “Tin Lizzie” – but the story behind the playful nickname is unclear. Some believe “Lizzie” was just a common name that people gave to horses, and the nickname was naturally carried over to Ford’s “horseless carriage,” another popular early 20th-century term for a motor vehicle.
Others claim it stems from a 1922 race at Pikes Peak, CO, where racer Noel Bullock called his Model T “Old Liz.” Bullock’s car had seen better days, and, according to observers, it resembled a tin can. Thus, the name “Tin Lizzie” was born.
Home Life
Henry Ford was born to William and Mary Ford on a farm in Dearborn, MI, in 1863. When he was just 16 years old, Ford decided to become a machinist and moved to Detroit in search of apprentice work. He returned to his family’s farm at 19, but his interest in machines and engines never ceased. When not working on the farm, Ford serviced steam engines and worked in factories before marrying Clara Bryant in 1888.
For the next few years, Ford ran a sawmill to make ends meet, but eventually the pair moved to Detroit. Within two years, Ford became chief engineer at the Edison Illuminating Company, and his only child, Edsel Bryant Ford, was born.
After establishing the Ford Motor Company, Ford faced widespread criticism for his political views, which included opposition to US involvement in World War I. Ford ran for the US Senate in 1918, “narrowly losing in a campaign marked by personal attacks from his opponent,” History.com noted.
After briefly stepping away, Ford became president of Ford Motor Company once again in the wake of his son’s death in 1943. Two years later, Ford gave control of the company to his grandson, Henry Ford II. In 1947, Ford passed away in his home in Dearborn at age 83. The company Ford started more than 120 years ago still operates to this day.
