Chaim Aron Kaplan, born in 1880 in Belarus, wrote his "Megillat yissurin" ("Scroll of Suffering") in the Warsaw ghetto. A Zionist who emphasized the role of history in Jewish culture, he wrote his diary in Hebrew for future historians, but lost his belief in God and feared that his diary may serve no purpose if the entire Jewish nation is annihilated. He was killed in Treblinka in 1942.
