journalist and author who became famous for his series of sociopolitical books describing and interpreting for American readers various regions of the world, beginning with Inside Europe (1936).

Gunther attended the University of Chicago, where he was elected to Phi Beta Kappa and earned a Ph.B. degree in 1922. Without waiting to receive his diploma, he embarked on a cattle boat bound for Europe. On his return he took a reporting job with the Chicago Daily News but relinquished it when the management declined to assign him as a European correspondent. He made his way to London and managed to gain a position on the Daily News London bureau, where he worked from 1924 to 1936. For the next nine years he covered various European capitals, the Balkan region, and the Middle East.

With the success of Inside Europe, Gunther quit the newspaper business to devote full time to book writing. He travelled widely while researching his books and in 1941 became a war correspondent, covering Gen. Dwight D. Eisenhower's headquarters in Europe and the British 8th Army. From 1942 to 1945 he reported on the war as a radio commentator on the National Broadcasting Company's Blue Network. He travelled in central and eastern Europe in 1948 for the New York Herald Tribune and Look magazine.

Gunther's other books—all highly successful—include Inside Asia (1939), The High Cost of Hitler (1939), Inside Latin America (1941), D-Day (1944), Inside U.S.A. (1947), Roosevelt in Retrospect (1950), Inside Africa (1955), Inside Russia Today (1958), Inside Europe Today (1961), and Inside South America (1967). His book Death Be Not Proud (1949) was a reminiscence of his son who died in youth.
