Hello friends and colleagues: Thank you for your consistent support and enthusiasm. I am delighted that so many people share my passion for Jewish history and thought, and consider it a rare privilege to share my research with you online and in person. I wish you all a blessed New Year of spiritual and material……

Hello everyone! Please visit this site for my translation of Rabbi Moshe Cordovero’s classic Tomer Devorah (The Kabbalah of Forgiveness), a text often studied at precisely this time of year as we strive to improve our relationships with each other, with G-d, and with ourselves. The site also features a series of brief videos on each……

The Jews of the Danube Fall 2018 Lecture Series From its headwaters in Germany’s Black Forest to its final destination in the Black Sea, the Danube River flows through ten countries and over ten centuries of Jewish history. Great cities like Vienna and Budapest punctuate its course through East-Central Europe, the cradle of much of……

The invisible yet palpable echo of the crypto-Jewish tradition resonates through Portugal like the far side of a conversation faintly overheard in another person’s cell phone. A rush of sibilants or an exclamation of laughter confirms the reality of the distant interlocutor, even though we do not see her before us. The history of Portugal’s…

Join me in this global effort to prepare for Rosh Hashanah and Yom Kippur this year!

Hasidim of the Aish Kodesh should take note: this is likely the face of one of the murderers of Rabbi Kalonymus Kalmish Shapira hy”d. Jakiw Palij, a longtime resident of Queens, New York, was recently extradited to Germany for filing false information while immigrating to the United States after World War II. Palij served as……

Hello students, friends and colleagues– We still have a few hours before the onset of Shabbat and the possible arrival of Mashiach, but if we have to make it through another Tisha B’Av– If you are in Fort Lee, NJ Sunday morning or Crown Heights, Brooklyn Sunday afternoon, please join me for presentations on the……

Thanks to Ben Rothke for this kind review of Torah from the Years of Wrath in this week’s Jewish Link of New Jersey. I am very grateful to be a part of the community that values and spreads the teachings of the Piaseczno Rebbe; nice to see positive reviews! Keeping the Faith By Ben Rothke……

Hello everyone– My father’s yortsayt is coming up next week, and as in previous years I hope to begin another cycle of study of Maimonides on Teshuvah. Please visit the Maimonides on Teshuvah page page to learn more about how to participate in this free, Global Study of Maimonides program. Posts will also appear……


I’m really thrilled to be cruising the Douro River this summer with Kosher Riverboat Cruises, lecturing on the history of Spanish and Portuguese Jewry (my wife plans to come along, which means I really have to bring my A-game). I just learned that there’s only 18 cabins left, so if you’re interested, please click the……

Conference presentation at the “The 100th Anniversary of the Ukrainian Revolution and the Proclamation of Ukraine’s Independence,” held at the Ukrainian Institute, New York, Sunday, January 21. My talk was inspired by a thought-provoking article in the Forward by Avital Chizik-Goldschmidt. A fascinating panel, which included Anna Procyk of CUNY, Serhy Yekelchyk of University of……

On Parashat Beshalah (January 20, 1940), a young rebel escaped from the notorious Pawiak Prison, located not far from the Piaseczno Bet Midrash. Andrzej Kott, the 21-year old leader of the military wing of a resistance movement called the Polish People’s Independence Action, was a child of assimilated Jewish parents who had converted to Christianity….…

The recent translation of the work of Rabbi Shimon Gershon Rosenberg (Rav Shagar, 1949-2007) promises to elevate his distinctive thought to a broader audience of readers (Faith Shattered and Restored: Judaism in the Postmodern Age), many of whom will resonate with Dr. Yitzchak Mandelbaum’s comment on his discovery of Rav Shagar: “I knew I had……

The Rebbe’s entry for Parashat Bo (January 13, 1940) is unusual. Recorded in the scribe’s careful hand, with minimal annotation, it has two bold diagonal lines drawn through the center of the text, indicating that the Rebbe rejected it altogether. A brief and uncharacteristic first-person comment is appended: “more of what we said I do……

Really nice to meet with Jésica Neuah of Editorial Perspectivas to work on the tentative cover and book design of the Spanish edition of The Kabbalah of Forgiveness! Great to work with her and the whole team. G-d willing the book will be released in the summer of this year.

I had chills listening to Rabbi Shlomo Katz review the Rebbe’s words on this week’s parashah. I am grateful for his kind words of praise for my recent book on the historical context of the Aish Kodesh, but to tell the truth, I hardly recognized my own words from the masterful treatment they received from……

Chaim Kaplan recorded the mood in the Warsaw Ghetto in January 1942: The cold is so intense that my fingers are often too numb to hold a pen. There is no coal for heating and electricity is sporadic or nonexistent. In the oppressive dark and unbearable cold your mind stops functioning. Yet even in such……

Five months into the Nazi occupation, the Jews of Warsaw struggled to keep up with the barrage of administrative decrees inflicted upon them by the Germans. When the Rebbe spoke on Parashat Vaera, which fell on January 6, 1940, the worst was still far off. The Nazis had replaced the leadership of the Jewish Council……

The winter of 5702 brutalized the Jews of the Warsaw ghetto with unforgiving cold. Chaim Kaplan, a school principal whose journal Scroll of Agony survived the war, recounts in his typically blunt prose how the physical privations of January 1942 affected the spiritual life of Ghetto inhabitants: Gone is the spirit of Jewish brotherhood. The……

On December 27, 1941, the Piaseczno Rebbe delivered his last recorded drashah on Parashat Vayigash in the Warsaw Ghetto. The previous month was especially brutal: an especially cold winter, combined with a severe coal shortage, exacerbated the typhus epidemic, and each morning a detail of the chevra kadisha patrolled the streets to collect the bodies……
