The journalist Walter Lippmann (1889-1974) was a magisterial figure who relished his role as an insider, an adviser to presidents, a shaper and sometime purveyor of government policy. Drawing on conversations with Lippmann and exclusive access to his private papers, Ronald Steel documents the broad flow of Lippmann's career from his brilliant Harvard days and his role in helping formulate Wilson's Fourteen Points in World War I to his bitter break with Lyndon Johnson over Vietnam. Written with clarity and objectivity, this definitive biography presents a commanding portrait of a complicated man and "guides its reader through the first three-quarters of this American century" (The New Yorker).
