Automobile Assembly Line

Assembly lines leverage standardized parts to break auto assembly into discrete components, each that can be done by a small number of people (often just one). Standardized parts evolved into standardized jobs.

Ransom Olds, inspired by a musket factory that used standardized parts with workers each focused on one part, created the first auto assembly line. Olds, the founder of Oldsmobile, did well. His cars sold for $150 less than Ford’s (pre-Model T). However, investors, determined to build pricier cars, pushed him out of his company.

The “disassembly” lines at Chicago slaughterhouses served as inspiration for Ford employee William Klann. One person repeatedly performs an individual task, butchering animals in stations. However, the single station factory is an old concept, arguably dating back to at least Arkwright-era factories.

Ford, via Klann, adopted the auto assembly line. He is generally (and wrongly) credited with the innovation of the auto assembly line.


It’s difficult, and arguably pointless, to separate the innovation of the automobile and Internal Combustion Engine (ICE). The use of an ICE for a “horseless carriage” was so obvious that early engines were all used for cars. Engine propelled buggies were, by far, the most popular use case though ICE’s also powered other applications.

Early Attempts

Nicolas-Joseph Cugnot in 1769 invented the first automobile, a steam-powered carriage created and driven around Paris. Cugnot’s three-wheel car was useful for carrying around equipment too heavy for horses. But the machine was clunky and difficult to control, eventually causing the first car crash. Cugnot’s car, banned on the streets or Paris, remains to this day in a Parisian museum. Cugnot received an honorary pension from King Louis XV.

In the United Kingdom, Richard Trevithick used a high-pressure steam engine he’d created to build a self-propelled car that he drove around with friends on Christmas Eve, 1801. That car burned up while Trevithick and friends drank at a nearby pub and failed to tend the fire powering the engine.

Trevithick later realized steam engines do not work well as automobiles and went on to innovate the locomotive. American Oliver Evans, a concurrent innovator of the high-pressure steam engine, also used his as a hybrid car/boat in 1805; he also abandoned it as impractical.

First Real Cars

French brothers Niépce, inventors of photography, built and patented the first ICE car in 1807. France was still reeling from the post-revolution political instability and finding investors in a new technology proved difficult. The brothers focused their work on England, where they improved their engine and automobile, but still failed to gain traction. However, they eventually moved on to photography where they had more success commercializing their innovation.

Fellow Frenchman François Isaac de Rivaz also claimed to innovate a hydrogen-powered internal combustion engine in 1807 though the details are sketchy.

Decades passed with little progress until Lenoir created a coal gas-powered internal combustion engine and car to drive with. Lenoir’s car was the first mass-produced (using standards at the time) automobile. Jules Verne noted in his 1863 novel, Paris in the Twentieth Century, that the streets of Paris would be filled with “the Lenoir machine.” Besides cars, Lenoir’s ICE was also used for small engines: printing presses, pumps, tools, etc…

Otto & Daimler: Liquid Fuel Cars

German Nikolaus Otto created the first modern engine that used liquid fuel and ran on the same principles. Otto realized the Lenoir engine was inefficient and loud due to its origins as a steam engine. Otto built and commercialized a different type of engine that had four separate actions, the four-stroke engine. His engine would 1) fill a piston with coal-gas and air, 2) compress the mixture, 3) ignite the mixture, producing movement, and 4) release the exhaust.

Gottlieb Daimler, who had worked with Otto, started a company to produce his own engines, using legal trickery to void Ott’s patents and avoid paying royalties. With Otto’s patent voided, Karl Benz also started a car company.

In 1885, both Daimler and Benz – who had two separate companies – changed their engines from coal gas to liquid fuel that was easier to manage. To make the fuel ignite they invented the carburetor, which turned the liquid into a flammable aerosol.

In 1895, Frenchman Levassor changed the body of an automobile from a horse carriage, with a motor on bottom, to a lower vehicle with the motor in front and gears for different speeds, the modern car. Levassor, who won the first major car race, died the next year from injuries sustained in a race and never had a chance to build a company. His competitor and sometimes collaborator, leading French bicycle maker Armand Peugeot, created an early auto company.

Daimler and Benz cars were extremely expensive, and many car companies formed, also creating high-cost cars. Ransom Olds formed an auto company in 1897, being the first to use standardization and an assembly line to build affordable cars.

Interesting note: the French repeatedly had first-mover advantage in cars and engines but never managed to commercialize their work as effectively as the Americans and Germans.
