In 1924, Gipson was appointed professor of history at
Lehigh University, a position he held until his death. Although best known as a historian of Colonial America and its place in the British Empire, two of Gipson's earliest articles had to do with the
Civil War and Reconstruction. His assessment of Andrew Johnson ("The Statesmanship of President Johnson: A Study of the Presidential Reconstruction Policy") was published in the
Mississippi Valley Historical Review in December 1915; and "The Collapse of the Confederacy" appeared in the
Mississippi Valley Historical Review in March 1918. His Yale doctoral dissertation, which was written under the guidance of Charles M. Andrews, was accepted in 1918 and published two years later by
Yale University Press as
Jared Ingersoll: A Study of American Loyalism in Relation to British Colonial Government (1920), for which he received the
Justin Winsor Prize from the
American Historical Association. He contributed seven entries to the
Dictionary of American Biography, and three articles to the
Dictionary of American History. Gipson's magnum opus was the fifteen-volume series
The British Empire Before the American Revolution (15 vols., 1936–70) - the first three volumes were published by The Caxton Printers in Caldwell, Idaho, and the remaining volumes were published by Alfred A. Knopf in New York. Gipson spent decades on the project, completing the final volume only shortly before his death. Three of the volumes were given significant historical prizes: •
The Great War for the Empire: The Years of Defeat, 1754-1757 (volume 6): The 1948
Columbia University Loubat Prize •
The Great War for the Empire: The Victorious Years, 1758-1760 (volume 7): The 1950
Bancroft Prize of
Columbia University •
The Triumphant Empire: Thunderclouds Gather in the West, 1763-1766 (volume 10): The 1962
Pulitzer Prize in History Gipson believed that the American Revolution was a direct result of changes that occurred in the British Empire after 1763, due to Britain's victory in the French and Indian War/Seven Years' War, which he referred to as "The Great War for the Empire." His thesis is succinctly presented in his article "The American Revolution as an Aftermath of the Great War for the Empire, 1754-1763," which was published in the March 1950 issue of
Political Science Quarterly. He paid tribute to his mentor in "Charles McLean Andrews and the Re-orientation of the Study of American Colonial History," which appeared in the July 1935 issue of the
Pennsylvania Magazine of History and Biography. One of Gipson's last publications was the introduction to a 1969
Festschrift for
Ross J. S. Hoffman, who was a history professor at
Fordham University. Gipson noted that he himself was a member of the
Congregational Church and a descendant of the pilgrim
William Brewster, while Hoffman was a convert to
Roman Catholicism and a staunch defender of that faith - and yet they were good friends. Gipson died on September 26, 1971, in Bethlehem, Pennsylvania; his ashes were buried in Caldwell. He left his entire estate to Lehigh University, providing the core funding for the Gipson Institute. ==See also==
