There is a miscellaneous text by Janusz Korczak (the Polish Jew who perished in Treblinka along with 200 children and staff of the orphanage he directed) that is titled, “How I Will Live after the War.”

In it, he notices how “about fifteen of them are keeping journals.” Most of the journals document life day-to-day and, occasionally, there are reminiscences about the past. However, “only once did someone write about what he was going to do after the war.”
