where his efforts were nationally acclaimed. In March 1904, a review in Metronome called the band an "up-to-date aggregation of capable musicians trained in every respect for high-class concert work." "Besides performing "their own quaint Indian songs they played Gounod, Mendelssohn, Mozart and Wagner". In 1904, Wheelock's Haskell Indian Band performed at the Louisiana Purchase Exposition, known as the St. Louis World's Fair. The band performed a mixture of classical and popular music, and Wheelock's Aboriginal Suite. This included Native dances and war whoops by band members. The Carlisle Indian Band also performed at the Pennsylvania state pavilion. That year Captain Pratt was forced out of his post as superintendent at Carlisle by BIA officials. His network of philanthropists stopped donating to American Indian music, and Wheelock faced a financial struggle. He was supporting an aging father, numerous siblings, wife and son. He resigned from Haskell to seek better-paying employment. Society of American Indians Wheelock was among the 50 founders in 1911 of the Society of American Indians (1911-1923), the first national American Indian rights organization developed and run by American Indians. The Society pioneered 20th-century Pan-Indianism, the philosophy and movement promoting unity among American Indians regardless of tribal affiliation. The Society was a forum for a new generation of American Indian leaders known as Red Progressives: they were mostly prominent professionals from the fields of medicine, nursing, law, government, education, anthropology, ethnology and ministry. They shared an enthusiasm and faith in the inevitability of progress through education and governmental action. The Society met at academic institutions, maintained a Washington headquarters, conducted annual conferences, and published a quarterly journal of literature by American Indian authors. The Society promoted an "American Indian Day", and led the fight for Indians to have United States citizenship. It lobbied to have U.S. Court of Claims available to hear cases of all tribes and bands in United States. The Society of American Indians was the forerunner of modern organizations such as the National Congress of American Indians. It anticipated important Indian reforms: a major reorganization of the Indian school system in the late 1920s, the codification of Indian law in the 1930s, and the opening of the U.S. Court of Claims to all Indian nations in the 1940s. Petition to President Woodrow Wilson In October 1914, Wheelock hosted the society's 1914 annual convention in Madison, Wisconsin. In December 1914, the society met in Washington, D.C.,
