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 Bridge Association
The desire to compete in the sport of tennis despite the racial barriers of the time resulted in the creation of the American Tennis Association in 1916. The Association often held its matches on college campuses such as Hampton Institute, now Hampton University, and Lincoln University, where adequate facilities were available. One such championship event was held at Hampton in the year, 1932. At the conclusion of the tournament, a group of tennis players, who were also bridge enthusiasts, suggested having a duplicate bridge match in the evening as a form of relaxation. This event, coupled with impetus from the Cromwell School of Contract Bridge in New York City, marked the beginning of the American Bridge Association. Dr. M.E. DuBisette became the first president of the ABA and the first National Bridge Tournament was held in Buckroe Beach, Virginia in 1933.
