Loy Henderson (1892-1986) ranks among the most important dozen or so American Foreign Service officers of this century. These memoirs, written after he retired in 1961, concentrate on his intimate involvement with U.S.-Soviet relations up to 1938: the period of nonrecognition, the negotiations of 1933, and the problems of representation in Moscow during the tenure of Ambassadors William G. Bullitt and Joseph E. Davies. The style is formal and discreet, reminiscent of the thousands of solid memoranda and cables Henderson wrote during his long career. He is charitable toward fellow Americans, dour and without illusions about Soviet leaders and their policies. The introduction by George Baer is helpful and perceptive.
