John Flournoy Montgomery (September 20, 1878 – November 7, 1954) was an American businessman and diplomat. His sole diplomatic posting was as U.S. Minister to Hungary, between 1933 and 1941. This ambassadorial assignment placed Montgomery at the center of the seething intrigue and gathering storm that characterized 1930's Hungary and Central Europe; in particular he was witness to the rise of Adolf Hitler's influence in Budapest, and the complex struggle over the alliance between Hungary and Nazi Germany. His memoirs, entitled Hungary: The Unwilling Satellite, are considered a valuable document of that era. Source: Wikipedia (en)
