Diaries kept during his years as head of the Tennessee Valley Authority and of the Atomic Energy Commission, among other important posts, form an autobiography of an important, versatile statesman.

When George C. Marshall became Secretary of State in January of 1947, he faced not only a staggering array of serious foreign policy questions but also a State Department rendered ineffective by neglect, maladministration, and low morale. Soon after his arrival Marshall asked George F. Kennan to head a new component in the department's structure--the Policy Planning Staff. Here Wilson Miscamble scrutinizes Kennan's subsequent influence over foreign policymaking during the crucial years from 1947 to 1950.
