Max Oscar Otto Koischwitz (February 19, 1902 – August 31, 1944) was a German-American who directed and broadcast Nazi propaganda against the United States during World War II.
He spoke on literature, music, drama, philosophy and geopolitics, his broadcasts being anti-Semitic, anti-British, anti-Roosevelt, Sinophobic, and anti-communist in tone.
In Berlin, Koischwitz began a relationship with another American working for German state radio, Mildred Gillars, who would become widely known as ‘Axis Sally’.
[8] Koischwitz broadcast for almost the entire war, towards its end appealing for the United States to join Germany in fighting the approaching Red Army.
On July 26, 1943, Koischwitz, along with Fred W. Kaltenbach, Jane Anderson, Edward Delaney, Constance Drexel, Robert Henry Best, Douglas Chandler and Ezra Pound, was indicted in absentia by a District of Columbia grand jury on charges of treason.
