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.
Arthritis Foundation
Organized in 1948 as the Arthritis and Rheumatism Foundation, the organization's name was changed in 1964 to the Arthritis Foundation. The following year, the American Rheumatism Association (ARA) merged with the Foundation. In 1965, an additional professional society, Allied Health Professions, was established within the Foundation; its name was changed to the Arthritis Health Professions Association (AHPA) in 1980. The American Juvenile Arthritis Organization (AJAO) was established in 1981 as a membership group within the Foundation; in 1991, AJAO became a council of the Foundation. In 1986, the ARA became a separate, independent organization and now is known as the American College of Rheumatology (ACR). In 1994, the AHPA became a division of the ACR and changed its name to the Association of Rheumatology Health Professionals.
