Today is the third yahrzeit of the attack. In Yiddish, yahrzeit literally means "time of year," and it usually refers to the anniversary of a person's death on the Jewish calendar. The October 27 attack originally occurred on the 18th day of the Hebrew month of Cheshvan, which falls this year on October 24.

This year, as in the past two years, the season will be marked with communal Torah study, volunteer service opportunities, and a public commemorative ceremony. And it will be quietly marked by an untold number of private gatherings and personal reflections, some of which may never be widely known beyond the intimate confines in which they occur.

This year also brings the publication of a book and the coming premier of two feature-length documentary films about the attack, as well as a large conference reckoning with October 27 and its aftermath from many angles.

Joshua Angrist and several colleagues were recently awarded the Nobel Prize in Economics "for their methodological contributions to the analysis of causal relationships." Angrist was raised in Pittsburgh in the 1960s and 1970s. He attended Wightman School, Linden Elementary School, and Taylor Allderdice High School. His family have long been active at Congregation Dor Hadash, and the Congregation Dor Hadash Records [MSS 410] at the Rauh Jewish Archives even contain his bar mitzvah announcement from September 1973.
