American Automobile Association (AAA) is a federation of motor clubs throughout North America. AAA is a privately held not-for-profit national member association and service organization with over 60 million members in the United States and Canada. It provides services to its members, including roadside assistance and others. Its national headquarters are in Heathrow, Florida.

It was founded on March 4, 1902, in Chicago, Illinois, in response to a lack of roads and highways suitable for automobiles. The first AAA road maps were published in 1905, and in 1917, it began printing hotel guides. The AAA began its School Safety Patrol Program in 1920, the first of the association's driver safety programs that provided local schools with materials, including badges and ID cards, to train and organize students into a patrol force. The AAA Foundation for Traffic Safety, which conducts studies on motorist safety, was established as a separate entity in 1947. In the 1960s, AAA helped draft the National Traffic and Motor Vehicle Safety Act of 1966, setting safety standards for automobiles, tires, and equipment. AAA also helped draft the Highway Safety Act, specifying standards for motor vehicle inspection and registration, motorcycle safety, driver education, driver licensing, traffic courts, highway design, construction, maintenance, and traffic control devices. During the Jim Crow era, AAA actively discriminated against African Americans, who could not join the association. Alternatives to AAA guides, such as The Negro Motorist Green Book, were written.

The American College of Mechano-Therapy operated in Chicago, IL, between roughly 1905 and 1920. It was founded by William Charles Schulze, an 1897 graduate of Rush Medical College and practicing MD licensed in Illinois, Minnesota, and Wisconsin. Schulze was born in Germany in 1870. Schulze incorporated the American College of Mechano-Therapy in 1907 and served as its president. Purporting to be the “largest eclectic school of drugless healing in the world,” the College offered a training course via correspondence. Though heavily criticized by the medical establishment, mechanical methods of healing nonetheless were increasingly popular in North America in the early part of the 20th century.
