Pyle, one of the foremost illustrators in the United States at the time, began teaching art classes at Drexel University in 1895. However, he was dissatisfied with the confines of formal art education, and beginning in 1898, he began teaching students during the summers at the Turner Mill in Chadds Ford. The mill, alongside the Brandywine, provided views of a scenic landscape to inspire the artists. In 1900, Pyle left Drexel and opened his own school attached to his personal art studio. Pyle created this school so that he might train a generation of illustrators who were artistically and financially successful. He hoped that through this, he would foster an American style of painting, something he felt the country lacked. In order to develop that intrinsically American style, Pyle believed that his students must spend time outdoors, taking in the scenery and the history of their country. To help facilitate this, Pyle frequently brought his students to Chadds Ford, where he would tell his students stories about the area’s revolutionary history while they painted landscapes. Pyle advocated against studying in Europe, hoping that his students would find fame and success through an American education. The school and studio, which are still standing, are located a short walk from the Brandywine Park, a stretch of riverside park designed by Frederick Law Olmsted. Of the 500 students who applied to attend Pyle's school in its first year, only twelve were accepted. It was through the absorption of Pyle's particular style and teaching that the tradition known as the "Brandywine School" emerged. Pyle continued to operate the school until 1910, during which time he was mentor to such successful artists as N. C. Wyeth, Frank E. Schoonover, Stanley M. Arthurs, William James Aylward, Thornton Oakley, Violet Oakley, Clifford Ashley, Anna Whelan Betts, Ethel Franklin Betts, Ellen Bernard Thompson Pyle, Jessie Willcox Smith, Olive Rush, Blanche Grant, Philip R. Goodwin, Allen Tupper True, and Harvey Dunn. In all, 75 artists were trained by Pyle during the ten years he ran his school in Wilmington. The Brandywine School continued on in Pyle's students even after his death in 1911. Several of his students, inspired by Pyle's example, taught the next generation of the school's students. In 1905, Wilmington philanthropist Samuel Bancroft constructed a set of buildings to house and provide studios for four of Pyle's most successful students: Wyeth, Schoonover, Dunn, and Ashley. Schoonover remained in his studio for the next 63 years, and in 1942 he used it to open his own school, where he taught artists such as Ellen du Pont Wheelwright. After Pyle's death, Arthurs purchased the Pyle studio and continued the school from 1912 to 1950. Wyeth stayed in his Wilmington studio for a time before moving to Chadds Ford, where he taught his own children, including artist Andrew Wyeth. The style was a source of inspiration for, and used extensively by Disneyprevisualization artists for the animated film, Treasure Planet.
