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.
National German-American Alliance
The National German-American Alliance (NGAA; German: Deutschamerikanischer National-Bund), was a federation of ethnic German associations in the United States founded in Philadelphia, Pennsylvania on October 6, 1901. Charles John Hexamer was elected its first president, and served until 1917. The mission of the NGAA was to "promote and preserve German culture in America"; it essentially sought to resist the assimilation of Germans in America. At the peak of its growth, around 1916, the national organization had chapters in forty-five states, and the District of Columbia, and a membership of approximately 2.5 million people.
