The American Heart Association (AHA) is a non-profit organization in the United States that funds cardiovascular medical research, educates consumers on healthy living and fosters appropriate cardiac care in an effort to reduce disability and deaths caused by cardiovascular disease and stroke. Originally formed in New York City in 1924 as the Association for the Prevention and Relief of Heart Disease, it is currently headquartered in Dallas, Texas. The American Heart Association is a national voluntary health agency.
National Bar Association
The National Bar Association was established in 1925 as the "Negro Bar Association", after Gertrude Rush, George H. Woodson, S. Joe Brown, James B. Morris, and Charles P. Howard, Sr. were denied membership in the American Bar Association. The young Charles Hamilton Houston, future dean of Howard University Law School, also helped with the founding. 
Its first president was George H. Woodson of Des Moines, Iowa. Arnette Hubbard became the NBA's first female president in 1981.
