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 Quarter Horse Association
The American Quarter Horse Association was born at a meeting on March 15, 1940 in Fort Worth, Texas. The original idea had come from articles published by Robert M. Denhardt during the 1930s about the history and characteristics of the quarter horse. In an article entitled "The Quarter Horse, Then and Now" in a 1939 "Western Horseman" magazine, Denhardt also suggested that those interested in forming a breed registry meet in Fort Worth to discuss the idea and hopefully act on the idea. About seventy-five people met in Fort Worth to discuss the proposals, with the eventual decision being to form a non-profit stock holding association in Texas to be the registry. Thirty-six people bought stock at the initial meeting. A board of directors and officers were selected.
