Henry Ford (July 30, 1863 – April 7, 1947) was the American founder of the Ford Motor Company and father of modern assembly lines used in mass production. His introduction of the Model T automobile revolutionized transportation and American industry. He was a prolific inventor and was awarded 161 U.S. patents. As owner of the Ford Motor Company he became one of the richest and best-known people in the world. He is credited with "Fordism", that is, the mass production of large numbers of inexpensive automobiles using the assembly line, coupled with high wages for his workers. Ford had a global vision, with consumerism as the key to peace. Ford did not believe in accountants; he amassed one of the world's largest fortunes without ever having his company audited under his administration. Henry Ford's intense commitment to lowering costs resulted in many technical and business innovations, including a franchise system that put a dealership in every city in North America, and in major cities on six continents. Ford left most of his vast wealth to the Ford Foundation but arranged for his family to control the company permanently.

Henry Ford was born July 30, 1863, on a farm in Greenfield Township (near Detroit, Michigan). His father, William Ford (1826–1905), was born in County Cork, Ireland. His mother, Mary Litogot Ford (1839–1876), was born in Michigan; she was the youngest child of Belgian immigrants; her parents died when Mary was a child and she was adopted by neighbors, the O'Herns. Henry Ford's siblings include Margaret Ford (1867–1938); Jane Ford (c. 1868–1945); William Ford (1871–1917) and Robert Ford (1873–1934).

His father gave Henry a pocket watch in his early teens. At fifteen, Ford dismantled and reassembled the timepieces of friends and neighbors dozens of times, gaining the reputation of a watch repairman. At twenty, Ford walked four miles to their Episcopal church every Sunday.
