Łódź Ghetto
In 1939, Rosenfeld's wife emigrated to England in anticipation of him following, but the outbreak of Second World War made his emigration impossible. In November 1941, Rosenfeld was deported to the Łódź Ghetto in Poland, along with 5,000 Jews from Prague. From June 1942 on, he worked in the Ghetto archive, where he took part in publication of the community's chronicle and wrote for its lexicon.
