ALBERT E. KAHN, at thirty-seven, has earned an international reputation for his sensational exposes of secret diplomacy, fifth column intrigue, and the machinations of men in high places. His books, as Walter Winchell once said of them, "pull no punches, name names." A graduate of Dartmouth College, where he was a famous athlete and winner of the Crawford-Campbell Literary Fellowship, Mr. Kahn became, in 1938, the Executive Secretary of the American Council Against Nazi Propaganda whose Honorary Chairman was the late William E. Dodd, former U.S. Ambassador to Germany. During the war years Mr. Kahn was editor of The Hour, a newsletter which achieved nationwide prominence for its numerous revelations and news scoops concerning fascist agents and Axis espionage rings. In 1942, in collaboration wdth Michael Sayers, Mr. Kahn wrote Sabotage! The Secret War Against America. Reprinted in Reader's Digest, Sabotage! became one of the most widely discussed books in the country. Together with Michael Sayers, Mr. Kahn wrote two more bestsellers: The Plot Against The Peace (1945). and The Great Conspiracy (1946). The Great Conspiracy, which sold a quarter of a million copies in the United States, has been printed in probably more foreign lands than any other non-fiction book published in the last decade. Among the 25 languages in which The Great Conspiracy has appeared are French, Russian, German, Swedish, Hungarian, Bulgarian, Italian, Dutch, Portugese, Polish, Slovakian, Danish, Norwegian, Roumanian and Bengali. The world circulation of the book runs into millions. High Treason appears to be headed for the same international acclaim. Arthur Kahn, research and editorial assistant to Albert E. Kahn in the writing of High Treason, served in the Office of Strategic Services during the war, and after V-E Day was appointed Chief Editor of Intelligence, Information Control Division of the Military Government in Germany. He is the author of Betrayal, The American Occupation of Germany. The two Kahns are not related.
