This is a Davar Torah or sermon (click on link) I gave at Park Slope Jewish Center during Shabbat morning services on June 22, 2019, which was my brother Robert's 26th yahrzeit (death anniversary) on the Jewish calendar. I gave a shorter version of the same talk at AltShul two weeks earlier.
"well written, masterfully translated by Jessica Cohen, and rewards rereading." -- From my review of The Diamond Setter by Moshe Sakal in New York Journal of Books
