Andergassen was born on July 30, 1908, in
Hall, Tyrol (then part of
Austria-Hungary). He later was educated as a machinist at
Swarowski in
Wattens. In 1929, he voluntarily joined the Army and was trained at
Arsenal (Vienna). In 1937, he was promoted to
Gendarm. After
Anschluss, he became a member of the
NSDAP, as well as becoming active with the
Gestapo. During the German occupation of Czechoslovak
Sudetenland in October 1938, he served in a 100-strong police unit; subsequently thereafter, he started his career as a Gestapo officer in Innsbruck. Andergassen was later relocated to Italy, where he served as an
SD officer in
Merano. On the night of September 15, 1943, he led a raid which resulted in the arrests of 25 Jewish citizens living in Merano. Andergassen locked those he found in a basement which was fashioned into a jail, and eventually deported them to the Reichenau concentration camp in
Austria, and finally,
Auschwitz concentration camp. Only one of the abducted, Valeska von Hoffmann, survived the Holocaust. He was at the rank of
SS-Sturmscharführer, and later promoted to SS-Untersturmführer during a tour of Northern Italy. == War crimes ==
