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 Amateur Hockey League
The American Amateur Hockey League was an amateur ice hockey league in the United States. The league was founded in 1896, and was based in New York City and New Jersey, until 1914, when the Boston AA joined the league. In the 1900–01 season a team from Philadelphia, the Quaker City Hockey Club, also played in the AAHL. The league ceased operations after the 1916–17 season.
