Dunning began teaching at Columbia and was steadily promoted on the academic ladder (fellow, lecturer, instructor, adjunct professor, and full professor); in 1903 he was appointed as the Francis Lieber Professor of History and Political Philosophy. Dunning had a dual role in history and political science. He was a long-time editor of
Political Science Quarterly. Although his health was poor after 1903, Dunning wrote numerous scholarly articles and book reviews for the
American Historical Review and the
Political Science Quarterly, which he edited from 1894 to 1903. Dunning was a founder and long-time activist of the
American Historical Association, becoming AHA president in 1913. He served as the president of the
American Political Science Association in 1922. In 1919 Dunning testified as an expert witness in a jury trial, one of the first historians to do. In 1916, the
Chicago Tribune called
Henry Ford "an
anarchist". Ford sued the
Tribune and its publisher
Robert McCormick for
libel, asking for $1M in damages. Ford's attorney, former
US Representative Alfred Lucking, retained Dunning to testify as to the definition and meaning of the term "anarchist." The Michigan jury determined that Ford was libeled but awarded him only six cents damages. Today, historians routinely testify as expert witnesses, and it could be said that Dunning established a precedent in doing so. Dunning's testimony may not have made much of an impact on the jury, since the jurors had not attended college, and other witnesses of high public standing testified, such as Major Generals
Leonard Wood and
William Harding Carter. Evaluating his contributions in 2000, Smith says Dunning was far more important as a graduate teacher than as a research scholar. Columbia was a leading producer of PhDs, and Dunning directed much graduate work in U.S. history and in European political thought. His students included future leading scholars and academic entrepreneurs, such as
Charles Merriam,
Harry Elmer Barnes,
James Wilford Garner, and
Carlton J. H. Hayes. He also mentored
C. Mildred Thompson, the history professor who became dean at
Vassar College. Thompson drafted the charter for
UNESCO (the United Nations Education, Scientific and Cultural Organization), and worked for
civil rights in Atlanta. Dunning gave lifelong support to his students, providing continuous encouragement in their careers. They honored him with a
Festschrift in 1914:
Studies in Southern History and Politics Inscribed to William Archibald Dunning ... by His Former Pupils the Authors. ==School of thought==
