Tuhia he haere tonu mō tēnei wāhanga - I whakaorangia a Budapest i te marama o Hānuere me Hui-tanguru 1945. I noho a Grossmann hei mema o te American Jewish Joint Distribution Committee me te tiamana-tiamana o te Hungarian Zionist Association. I noho ia hei kaiwhakahaere o te tari Budapest "Eretz-Israel". I uru hoki ia ki te whakauru ano i te tini o nga rerenga i hoki mai na roto i te hanganga o te 31 o nga mahi ahuwhenua me te 50 o nga mahi tauhokohoko. Heoi, i te mea pouri, ko te hinganga o te National Socialism
kihai i whakamutu i te whakahāwea ā-iwi. Ko ngā tau 1940 he tekau tau o te horoi ā-iwi kei te haere tonu puta noa i te nuinga o Ūropi ki waenganui. Ehara i te mea he Hurai a Grossmann, engari he kaikōrero Tiamana tōna reo. I te tau 1949 ka wehe ia i Hungary.
