being able to produce qualified teachers. This new institution eventually became Tuskegee University. Embracing much of Armstrong's philosophy, Washington built Tuskegee into a substantial school and became nationally famous as an educator, orator, and fund-raiser as well. He collaborated with the philanthropist Julius Rosenwald in the early 20th century to create a model for rural black schools; Rosenwald established a fund that matched monies raised by communities to build more than 5,000 schools for rural black children, mostly in the South. In 1888 Washington recruited his Hampton classmate Charles W. Greene to Tuskegee to lead the Agriculture Department. Together they enticed George Washington Carver to the Tuskegee Agriculture faculty upon his graduation with a master's degree from Iowa State University in 1896. Carver provided such technical strength in agriculture that, in 1900, Washington assigned Greene to establish a demonstration of black business capability and economic independence off-campus in Tuskegee. This project, entirely black-owned, comprised 4,000 lots of real estate and was formally established and designated Greenwood in 1901, as a demonstration for black-owned business and residential districts in every city in the nation with a significant black population. After Washington visited Tulsa, Oklahoma, in 1905 and addressed a large gathering there, the Oklahomans followed the Tuskegee model and named Tulsa's black-owned and operated district "Greenwood" in 1906. Native Americans In 1878, Hampton established a formal education program for Native Americans to accommodate men who had been held as prisoners of war. In 1875 at the end of the American Indian Wars, the United States Army sent seventy-two warriors from the Cheyenne, Kiowa, Comanche and Caddo Nations, to imprisonment and exile in St. Augustine, Florida. Essentially they were used as hostages to persuade their peoples in the West to keep peace. Lieutenant Richard Henry Pratt supervised them at Fort Marion and began to arrange for their education in the English language and American culture. St. Augustine was attracting numerous visitors from the North as it became known as a winter resort. Many became interested in the Native Americans held at Fort Marion and volunteered as teachers. They also provided the men with art supplies. Some of the men created what is now known as ledger art in this period. Some of the resulting works (including by David Pendleton Oakerhater) are held by the Smithsonian Institution. At the end of the warriors' incarceration, Pratt convinced seventeen of the younger men to enroll
