01 / The Detroit story
The Detroit story
Wills moved to Detroit with his family as a child and apprenticed as a toolmaker at the Detroit Lubricator Company, where his father worked. In 1899 he began helping Henry Ford in early mornings and late evenings at the Detroit Automobile Company, and by 1902 he was working full time on Ford's 999 and Arrow racers. When Ford Motor Company was founded in 1903 he became chief designer and metallurgist; too poor to buy stock, he was given a share of Henry Ford's profits. He championed light, strong vanadium steel and was the leading contributor to the Model T's design; he is also widely credited with drawing the Ford script logo. Wealthy but at odds with Ford, he left in 1919 and founded Wills Sainte Claire in Marysville, on the St. Clair River, building an advanced, costly car with a V-8 engine from 1921 to 1927. He later worked as a consultant, including for Chrysler, and died in Detroit in 1940.
