    Honored to receive this Review by the Kosher Bookworm

    Please click here to read the review at The Jewish Star. By Alan Jay Gerber The name and history of the Aish Kodesh in our community is well known. This legacy from the tragedy of the Warsaw Ghetto of one of its towering leaders, Rebbi Kalonymus Kalmish Shapira, the Aish Kodesh, has been taught to us…

  • Thank you.

    Thank you.

    I was deeply moved by the kind support of my research into the life of the Aish Kodesh at the book launch this week. By all accounts, it was a wonderful evening–we had such a diverse crowd in attendance, from pious Hasidim well familiar with the Piaseczno Rebbe to students who knew nothing about his…

    Review by Rabbi Pesach Sommer

    Very grateful to Rabbi Pesach Sommer for writing a kind and generous review of Torah from the Years of Wrath! My favorite passage is at the end: “Dr. Abramson has written a book which is destined to lead to an increase of study of the rebbe’s Torah and thought in both the academic and Jewish…

    Deciphering the Rosetta Stone of the Holocaust

      The Aish Kodesh died 74 years ago, martyred in the Trawniki labor camp. Now, Rabbi Kalonymus Kalmish Shapira is at the center of a surge of new research into the most profound questions surrounding the Holocaust. A new critical edition, prepared with phenomenal scholarly energy by Daniel Reiser, demonstrates that we have just started…

  • Shavuot in the Warsaw Ghetto (1940)

    Shavuot in the Warsaw Ghetto (1940)

    Shimon Huberband was a student of the Rebbe and an amateur historian working for Emanuel Ringelblum’s underground Oneg Shabbat archive (Rabbi Huberband, who was killed along with Ringelblum and most of the archivists, was probably instrumental in convincing the Rebbe to entrust his manuscript to Ringelblum for burial). Rabbi Huberband  visited the court of Piaseczno…

    Parashat Emor in the Warsaw Ghetto (May 11, 1940)

    The brief sense of relief felt by Warsaw Jews at the beginning of Passover 1941 did not last. Decrees expelling Jews from several towns were scheduled for the intermediate days of the holiday, and pressures upon the Jewish community increased dramatically. Diarists of the Ghetto record widespread confusion among the population over new Nazi policies…

    The Walls of the Warsaw Ghetto: The Rebbe on Parashat Metsora, 1940

    In early April 1940, Warsaw Jews were distressed to witness the initial construction of walls in several parts of the city. Up until this point, the concentration of Jews in certain parts of Warsaw was effected by administrative decree, with few permanent physical structures demarcating the boundaries of the ghetto. Debates raged within the Nazi…
