Henry Ford's most notable contribution to the industry was the production assembly line process.  (letter D.)

Henry Ford was an American entrepreneur and mechanical engineer, founder of Ford Motor Company, author of the books My Philosophy of Industry and My Life and My Work, and the first entrepreneur to apply mass-production to mass-produce automobiles in less time and at a lower cost.

Ford is attributed to the large-scale production of cars at low cost through the use of the device known as "assembly line", which was able to manufacture a car every 98 minutes, in addition to the high salaries offered to its workers - notably the value of $ 5 a day, adopted in 1914.
