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 Philatelic Society
The organization, originally named the "American Philatelic Association", was established on September 14, 1886 in New York City, and the following day elected John K. Tiffany as its first president. Voting membership was granted to 219 individuals who paid two bits (25¢) for the privilege. The organization's name was changed to its present name for a few months in 1897, then back, then permanently in 1908.
