Now watch a clip of Hanuš Gaertner's testimony, in which he remembers Heinz.
Hanuš Gaertner was born in 1926 in Hamburg, Germany, his parents having moved to the city from Bohemia.
He lived in Prague from September 1938, joined the Zionist movement Maccabi Hatzair, and was deported to the ghetto in Terezín in August 1942. From Terezín he was deported further, to the Auschwitz-Birkenau death camp in December 1943. As one of the few prisoners of the so-called Terezin family camp, he was saved by having been selected for slave labour in the Schwarzheide camp. He survived the death march and was liberated in Terezín. He studied law, graduating in the early 1950s. In the heated atmosphere of the 1950s, he faced accusations of Zionism, and devoted himself to translating into German. In the summer of 1968, he never returned to his occupied homeland from a vacation in Switzerland. He lived in Germany, and after the fall of the communist regime, again in Prague.
The interview was recorded on 27 September 1996 in Pyšely.
