Walter Lippmann (September 23, 1889 – December 14, 1974) was an American public intellectual, writer, reporter, and political commentator famous for being among the first to introduce the concept of Cold War, coining the term "stereotype" in the modern psychological meaning, and critiquing media and democracy in his newspaper column and several books, most notably his 1922 book Public Opinion. His views regarding the role of journalism in a democracy were contrasted with the contemporaneous writings of John Dewey in what has been retrospectively named the Lippmann-Dewey debate. Lippmann won two Pulitzer Prizes, one for his syndicated newspaper column "Today and Tomorrow" and one for his 1961 interview of Nikita Khruschev. Lippmann was a journalist, a media critic and an amateur philosopher who tried to reconcile the tensions between liberty and democracy in a complex and modern world, as in his 1920 book Liberty and the News. In 1913, Lippmann, Herbert Croly, and Walter Weyl became the founding editors of The New Republic magazine.During World War I, Lippmann was commissioned a captain in the Army on June 28, 1918 and was assigned to the intelligence section of the AEF headquarters in France. He was assigned to the staff of Colonel Edward M. House in October and attached to the American Commission to negotiate peace in December. He returned to the United States in February 1919 and was immediately discharged from the Army.
