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.
National Aeronautic Association
The NAA was founded in 1905 as the Aero Club of America (ACA), by members of the Automobile Club of America. From its inception, ACA’s goal was to promote aviation in any way possible, as both a sport and a commercial endeavor. In 1922 it was incorporated as the Aero Club’s successor, and continued the original group’s mission of promoting aviation. 
The NAA has been steeply involved with the growth of aviation in the United States almost since its beginning, to the point of being the sole issuer of pilot licenses in American until the Civil Aeronautics Act of 1926.
The Chairman of the NAA is James Albaugh. The President and Chief Executive Officer of the NAA is Greg Principato.
