Why isn't Feodor Prissmann's Yahrzeit Exact?

We do not know the exact date of death of Feodor Prissmann. According to Jewish tradition, if the exact date of death is not known, the yahrzeit of a person can be observed on any day, as long as it is that same day every year. Since that is the case, we observe the yahrzeit of Feodor Prissmann on 8 Tevet. If you know the exact date of death of Feodor Prissmann, contact us via the contact page.
