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 Motor League
The American Motor League ("AML") was the first automobile organization in the United States, formed 1895. The AML started in Chicago from ideas of Charles Brady King. He wished to form an organization that governed the movement of the fast development of the manufacture of "horseless carriages" that seemed to be going in various haphazard directions in the United States. The AML was organized by King and he was given the first membership each year, No. 100.
