Rav Aaron Felder z”l


rav-aaron-felderIt is with great sadness that we report the passing of Rav Aaron Felder z”l, rov of Congregation B’nai Israel-Ohev Zedek in Philadelphia, PA. He was 70 years old.

Rav Felder was a renowned talmid chochom and posek who served as Director of Kosher Standards at the Kof-K and was a member of the Kof-K Bais Din and the Bais Din of Greater Philadelphia. A close talmid of Rav Moshe Feinstein zt”l, Rav Felder was sought after for his expertise in p’sak halacha and his guidance and dvice in myriad areas.

Rav Felder was a son of Rav Gedaliah Felder zt”l, originally of Istrik, Galicia, who was a noted posek, rov of Shomrai Shabbos-Chevrah Mishnayos Congregation in Toronto for forty years, and author of Yesodei Yeshurun and Nachlas Tzvi. Rav Gedaliah passed away in 1991.

Rav Felder spent 14 years with Rav Moshe Feinstein, learning the Torah and p’sak approach of his rebbi. Rav Felder was a renowned expert in the laws of gittin and was often consulted upon in matters relating to gittin, such as the spelling of certain English names.

Rav Felder authored the multi-volume Rishumei Aaron, which contains rulings and halachic opinions from Rav Moshe, as well as remarkable vignettes about Rav Moshe that are not found elsewhere. [For example, Rav Felder relates that Rav Moshe told him that while in Luban, he was married on a Friday afternoon. His own father was his mesader kiddushin and their sole sheva brachos was on Shabbos; there were no further sheva brachos, unlike the custom prevalent today.]

A teshuvah from Rav Moshe to Rav Felder can be found in Igros Moshe, Yoreh Deah, Vol. 4:43.

Rav Felder is survived by his children, Reb Yissochor Dov Felder, Reb Eli Felder, Mrs. Tzippy Weil, Mrs. Elisheva Rosenhan, Mrs. Nechama Kohn, Mrs. Hadassah Sperling, Mrs. Sari Bernstein, Mrs. Chani Engel, Mrs. Brochi Siff and Shirah Felder, and his siblings, Reb Yossi Felder of Baltimore and Rav Yacov Felder, rov of Shomrai Shabbos-Chevrah Mishnayos Congregation of Toronto.

The levaya will take place today, Sunday, at 10:30 a.m., at Rav Felder’s shul, Congregation B’nai Israel-Ohev Zedek, located at 8201 Castor Avenue, at the corner of Solly Avenue, in Philadelphia. The aron will then be flown to Eretz Yisroel for kevurah in Bet Shemesh.

The family will be sitting shivah at 8019 Langdon Avenue, between Rhawn and Stanwod Streets, in Philadelphia, PA 19152.

Yehi zichro boruch.

  1. BDE
    A tzaddik that will be a great loss to all of klal yisroel.

    Sometimes I wonder if we really appreciate the gedolim we have today? the guidance we get from them, the daas torah they give us?

    Sometimes when we don’t appreciate something, Hashem takes it away from us until we stop taking it for granted.

    May his neshama have an aliya

  2. A true Talmid Chacham and a great person. I had the privilege of knowing Rabbi Felder for over twenty years and I asked him many questions. I am deeply saddened.

    The last question I asked him concerned halacha limasse whether a person could participate in stem cell research and he told me that you could.

    I cannot find the proper words to express how great a loss this is for all of Clall Yisroel.

  3. I knew him well, for years, and spent time with him occasionally.

    He was a man of emes, who, unlike many people who go around flattering others, telling them what they think they want to hear, said what he felt, said what had to be said, said what the Torah wanted.


    Halevai more people will follow him in those derochim.

  4. In response to #9 and #10 –

    Perhaps distant cousins, or not related at all, but not close relatives for sure.

  5. BD”E . This is a bitter pill to swallow. He was so full of chochma & wit, mamash a rov`s rov. All of his sefarim were reprinted numerous times and are extensively quoted. They are halacha lemaseh brief and to the point. I hope that he ksavim will be shared with the oilam hatorah .
    The niftar ZT’L was a cousin with the Felders of Boro Park . May we only hear besuros tovos.

  6. “The niftar ZT’L was a cousin with the Felders of Boro Park .”

    What I heard from a source from the older generation is that years ago, members of an earlier generation of the two mishpochos met and tried to figure out if/how they were related, and they couldn’t. Based on speculation due to the common name and coming from a certain part of Europe, it was concluded that they may be distantly related somehow. However, it is not for certain. Unless of course someone has found new information since then.

    Derech agav, what I heard from an older family member re a similar inyan (not sure if it was re the Felder family or another side), who heard it from someone from an older generation, is that the family had a yichus briv, family tree, or similar, written down. However, in the WWI period, they had to suddenly flee, like run for their lives, and it was lost.
