group. The new headmaster, Joseph Walton, had been a leading candidate for the presidency of Swarthmore College, the Hicksite-sponsored Friends college, in 1898. During Walton's tenure as head of George School (1901–1912), the school overcame what had been a troubled balance sheet by expanding. The school built a new dormitory, Drayton Hall, in 1903 (the school had built Orton in a fit of optimism in 1897), and the first separate classroom building, Retford Hall, in 1903. Unlike Maris, Walton opposed the idea of "guarded" education and encouraged arts education. Walton died of a duodenal ulcer, aged 57. George Walton, the son of Joseph Walton, served as headmaster from 1912 to 1948, the longest term of any head of school. There was little new construction during his term (the one major building was Bancroft Hall, built in 1931), but considerable social change. The enrollment nearly doubled, from 226 to 425, while the number of Quakers attending remained about the same, lowering the proportion. The school accepted its first black student in the 1940s and introduced social dancing and football. Outside of the school, he was a prominent voice within the Friends community. He was part of the group that founded the Pendle Hill study center in 1930; he accompanied two of that group, the well-known writer Rufus Jones and D. Robert Yarnall on a 1938 mission to Germany on behalf of the American Friends Service Committee to allow that group to distribute relief in Poland, then under occupation. After retiring from George School, he was an instrumental figure in reconciling the Hicksite and Orthodox Philadelphia Yearly Meetings in 1955. Following World War II, teacher Walter Mohr, who had also worked with the American Friends Service Committee, organized affiliations with two German schools, Jacobi Gymnasium for boys in Düsseldorf and Gertraudenschule for girls in Berlin, at first sending relief supplies and organizing student exchanges. In 1950, the first of almost twenty years of German workcamps began. In the late 1960s, these affiliations and work camps began to spread to Russia, Africa, and Latin America and included work projects domestically. The next headmaster, Richard McFeely, ushered in an era of campus growth and a change to a less formal relationship between students and faculty: McFeely insisted on being addressed by first name. McFeely was generally known as "Mr. Dick." McFeely had contracted polio while a student at Swarthmore. McFeely was friendly with Franklin
