This study traces the career of Robert Francis Kelley and his influence on American-Russian Relations during the nonrecognition period (1917-1933). The focus of this examination is Kelley's role in formulating, implementing, and sustaining America's anti-communist policy developed and solidified during the 1920s and 1930s. Particular attention is given to the senate recognition hearing of 1924, Kelley's training of future diplomats (George Kennan, Charles Bohlen, et al.), and his contributions to the preparations leading to the United States' recognition of Russia in 1933. Using Kelley's papers and personal correspondence, this study shows the growth of a man and the evolution of a policy.
