During Charles Stewart Mott's 60 years of service on the GM board of directors, he established the Mott Foundation in 1926. This foundation was created to improve Flint's civic welfare, which included Mott giving generous gifts to fund the community's education. The Mott Foundation continues to support Flint's growth and development. 

As a founder of the Durant- Dort Carriage Company and later a president of Dort Motor Car Company, Josiah Dallas Dort was heavily involved with the Flint Institute of Music, the Industrial Mutual Association, and Flint's parks. Mr. Dort encouraged young people to accept leadership positions in the community. 

As World War II was underway, there was a lack of male workers in the industry due to being sent off to war. The massive demand for wartime material gave women a place on the assembly line during the war. 

While the auto workers were on strike, the women did not stay in the shadows. Genora Johnson, a 23-year old wife of a strike leader at Chevrolet, led a group of women in picketing, staffing a first aid station, and even creating a nursery to care for children while their parents protested. 

To improve working conditions, on December 30, 1936, workers at the Chevrolet and Fisher Body plants sat down on assembly lines. Workers at the plants felt they were nothing more than robots on the assembly line. The sit-down strike forced General Motors to recognize their new union, the United Auto Workers. 

The Flint Vehicle Factories Mutual Association, and The Industrial Fellowship League merged on September 22, 1922 to benefit General Motors workers known as the Industrial Mutual Association. Even today, IMA provides special programs for member workers and their families. 

The Flint Varnish Works, which opened in 1901, supplied the first finishes used at the Buick Motor Company located at the corner of Hamilton and St. John Street. Less than 20 years later, DuPont acquired Flint Varnish Works and developed paints and finishes for every imaginable surface of an automobile. 

Albert Champion arrived in America in 1899, traveling from Paris to race bicycles but later started manufacturing spark plugs in Boston. Billy Durant convinced Mr. Champion to move his operations to Flint and the company was then named AC Spark Plug Company in 1909. 

Just as other companies who shifted from carraiges and buggy bodies to automobiles, Stewart Body Works transitioned into auto body production. The comapny produced bodies for automobiles for several different companies including Buick, the Flint Automobile Company, and the Little Motor Car Company. 

In 1919, the School of Automotive Trades was founded and in 1926, General Motors Institute acquired the school as it became an important training organization for GM. General Motors knew that having trained men producing automobiles for their company could keep the business growing and expanding to new avenues.
