American Heart Association
The American Heart Association grew out of a set of smaller precursor groups. The primary precursor was the Association for the Prevention and Relief of Heart Disease, formed in New York City in 1915, to study whether patients with heart disease could safely return to work. Several similar organizations formed or evolved in Boston, Philadelphia, and Chicago in the 1920s. Recognizing the need for a national organization to share research and promote findings, the American Heart Association was formed in 1924 by six cardiologists representing several of these precursor groups.
American Automobile Association
The American Automobile Association (the "AAA" or "Triple-A") was founded on March 4, 1902, in Chicago, Illinois, when in response to a lack of roads and highways suitable for automobiles, nine motor clubs with a total of 1,500 members banded together to form the Triple-A. Those individual motor clubs included the Chicago Automobile Club, Automobile Club of America, Automobile Club of New Jersey, and others. The Automobile Club of Buffalo joined in 1903.
