Dorothy Celene Thompson (9 July 1893 – 30 January 1961) was an American journalist and radio broadcaster, who in 1939 was recognized by Time magazine as being equal in influence to Eleanor Roosevelt. She is notable as the first American journalist to be expelled from National Socialist Germany in 1934 and as one of the few women news commentators on radio during the 1930s. She is regarded by some as the "First Lady of American Journalism". By war's end, she was regarded as one of the most effective spokespersons for Zionism.
Despite this, when she switched her views round radically after a trip to Palestine in 1945, she ran into difficulties, including accusations of anti-Semitism, which she strongly rebuffed, after being warned that hostility toward Israel was, in the American press world, "almost a definition of professional suicide".
