legislatures consistently underfunded black schools in their segregated system. To address those needs, in the 20th century, Washington enlisted his philanthropic network to create matching funds programs to stimulate construction of numerous rural public schools for black children in the South. Working especially with Julius Rosenwald from Chicago, Washington had Tuskegee architects develop model school designs. The Rosenwald Fund helped support the construction and operation of more than 5,000 schools and related resources for the education of blacks throughout the South in the late 19th and early 20th centuries. The local schools were a source of communal pride; African-American families gave labor, land and money to them, to give their children more chances in an environment of poverty and segregation. A major part of Washington's legacy, the model rural schools continued to be constructed into the 1930s, with matching funds for communities from the Rosenwald Fund. Washington also contributed to the Progressive Era by forming the National Negro Business League. It encouraged entrepreneurship among black businessmen, establishing a national network. His autobiography, Up from Slavery, first published in 1901, is still widely read in the early 21st century. Marriages and children Washington was married three times. In his autobiography Up from Slavery, he gave all three of his wives credit for their contributions at Tuskegee. His first wife Fannie N. Smith was from Malden, West Virginia, the same Kanawha River Valley town where Washington had lived from age nine to sixteen. He maintained ties there all his life, and Smith was a student of his when he taught in Malden. He helped her gain entrance into the Hampton Institute. Washington and Smith were married in the summer of 1882, a year after he became principal there. They had one child, Portia M. Washington, born in 1883. Fannie died in May 1884. In 1885, the widower Washington married again, to Olivia A. Davidson (1854–1889). Born free in Virginia to a free woman of color and a father who had been freed from slavery, she moved with her family to the free state of Ohio, where she attended common schools. Davidson later studied at Hampton Institute and went North to study at the Massachusetts State Normal School at Framingham. She taught in Mississippi and Tennessee before going to Tuskegee to work as a teacher. Washington recruited Davidson to Tuskegee, and promoted her to vice-principal. They had two sons, Booker T. Washington Jr.
