Hans Kamm was born in the German town of Breslau,
Silesia (now
Wrocław, Poland), on June 3, 1925 to a
Jewish family. Kamm attended a progressive collective school that closed in 1933. Then he had to go to a Jewish school. After the
Kristallnacht pogroms, Kamm's father was arrested in November 1938 and deported to the
Buchenwald concentration camp. After he was temporarily allowed to return home a few months later, he fled to Britain and later went to the United States. In January 1941, Hans Kamm and his mother also fled to the U.S., reached from Lisbon via a sealed train from Breslau. Kamm grew up in Manhattan, where he graduated from
George Washington High School. He became an American citizen in 1943, changing his name to Henry Kamm. At the age of 18 he enlisted in the army in 1944 and fought in Belgium and France, where he learned French. After the end of the war he was employed in
Dachau as an interpreter at trials against suspected Nazi war criminals. However, the work of defending the accused was difficult for him; after a week he ended his participation and left Germany. ==Career in journalism==
