Professor Coolidge never gave up his interest in the work. In addition to the courses that he gave, he superintended the building of the Slavic collection in the Harvard Library and served constantly as an adviser to the United States government on Slavic matters. He brought out, in 1915, a volume on the _Origin of the Triple Alliance_ and during World War I was one of the committee of scholars formed under the leadership of Colonel House to prepare materials for the American Delegation at the Peace Conference. In 1918 he served as a special representative of the American government in Sweden and north Russia, and in 1921 he was sent by the American Red Cross to negotiate with the Bolshevik government on famine relief. In 1922 he founded _Foreign Affairs_, the organ of the American Council on Foreign Relations and the leading journal in this field. He personally acted as editor until 1927 when he relinquished the task to Hamilton Fish Armstrong who had been in the American service in Serbia during World War I. When Professor Coolidge died in 1928, he was the undisputed dean of American Slavic historians and the inspiration for a large part of the work that was then being done in the United States. His influence on the development of studies in history was greater than that of Leo Wiener on languages and literature. Leo Wiener (1862–1939) published in 1902 and 1903 an _Anthology of Russian Literature_. This incorporated almost all the translations previously made, including excerpts from the greater Russian writers. The first volume, which included Russian literature up to Karamzin, still remains the best collection in English of the older literature. Where translations were unavailable, Professor Wiener made his own in prose. He also published in 1904 and 1905 a translation of the chief works of Tolstoy. Unfortunately in his later years, he lost interest in Russian and devoted his energies to studies of Ulfilas and the Gothic texts and many other questions far removed from his original field. A great many of the scholars who became prominent in Slavic history before and during World War I were students of Professor Coolidge, who thus became the dominant force in the development of historical studies for many years. Among these was Frank A. Golder (1877–1929) who developed Russian history at Stanford University. He stressed, as we might expect, the American contact with Russia in the north Pacific and the Russian explorations in that area. In 1914 he published _Russian Expansion in the Pacific (1641–1850)_ and later edited the accounts of Bering’s voyages.
