  Bowne gathered a group of talented disciples who carried on his work in a second generation. The most important among these were Edgar Sheffield Brightman, Albert C. Knudson (1873–1953), Francis J. McConnell (1871–1953), George Albert Coe (1861–1951), and Ralph T. Flewelling (1871–1960). While Howison had established the personalist tradition at the University of California, Berkeley, Flewelling took personalism to the University of Southern California, which became the second important twentieth-century center of personalist thought in the United States.  Flewelling also founded The Personalist, the journal that would serve as the forum for American personalism. In 1915, he published Personalism and the Problems of Philosophy: An Appreciation of the Work of Borden Parker Bowne. At Boston University, Brightman continued the studies in personalism, in time holding the Borden Parker Bowne chair of philosophy, while Knudson, having first taught classes in the Old Testament, moved into personalist theology. Meanwhile Walter George Muelder (1907–), professor of social ethics and Christian theology at Boston University and the University of Southern California, helped bridge the gap between the Bostonian and Californian schools, calling his doctrine “Communitarian Personalism.”
