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.
Alzheimer's Association
The Alzheimer's Association was founded by Jerome H. Stone with the help of several family members in Chicago, Illinois and incorporated in April 10, 1980 as the Alzheimer's Disease and Related Disorders Association, Inc. and is a non-profit American volunteer health organization which focuses on care, support and research for Alzheimer's disease. The Alzheimer's Association is the largest non-profit funder of Alzheimer's disease research. The organization has chapters and communities across the nation, with its national office located in Chicago and the public policy office in Washington D.C. Its mission is "to eliminate Alzheimer's disease through the advancement of research; to provide and enhance care and support for all affected; and to reduce the risk of dementia through the promotion of brain health."
