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.
League of American Bicyclists
Founded in Newport, Rhode Island, on May 30, 1880, as the League of American Wheelmen by Kirk Munroe and E. Charles Pratt, it soon became the leading national membership organization for cyclists in the United States. The League was also the governing body for amateur bicycle racing in the U.S. during the late 19th century. The organization's first officers were Charles Pratt as president, T.K. Longstreet as vice president, O.S. Parsons as corresponding secretary, J.F. Furrell as recording secretary, and H.L. Willoughby as treasurer. The board of directors consisted of two from each state having regularly organization clubs. Membership peaked at 103,000 in 1898.
