Rav Moses Feinstein (Hebrew: משה פיינשטײַן Moshe Faynshteyn; March 3, 1895 – March 23, 1986) was a Lithuanian Orthodox rabbi, scholar, and posek (an authoritative adjudicator of questions related to Jewish law), who was world-renowned for his expertise in Halakha, extreme gentleness and compassion, and was regarded by many as the de facto supreme halakhic authority for Orthodox Jewry of North America. In the Orthodox world, he is widely referred to simply as "Reb Moshe", and his halakhic rulings are often referenced in contemporary rabbinic literature.
Moshe Feinstein was born, according to the Hebrew calendar, on the 7th day of Adar, 5655 (traditionally the date of birth and death of the Biblical Moshe) in Uzda, near Minsk, Belarus, then part of the Russian Empire. His father David Feinstein was the rabbi of Uzdan. His mother was a descendant of talmudist Yom Tov Lipman, the Shlah HaKadosh, and Rashi. His father was a great-grandson of the Vilna Gaon's brother.
He studied with his father and also in yeshivas located in Slutsk and Shklov. He also had a close relationship with his uncle, Rabbi Yaakov Kantrowitz, rabbi of Timkovitch, whom he greatly revered and considered his mentor. He was appointed rabbi of Lubań, where he served for sixteen years. He married Shima Kustanovich in 1920 and had 4 children (Pesach Chaim, Fay Gittel, Shifra, and David) before leaving Europe. His son, Pesach Chaim, died in Europe and his son, Reuven, was born in the US. Under increasing pressure from the Soviet regime, he moved with his family to New York City in 1936, where he lived for the rest of his life.
Settling on the Lower East Side, he became the rosh yeshiva of Mesivtha Tifereth Jerusalem. He later established a branch of the yeshiva in Staten Island, New York, now headed by his son Rabbi Reuven Feinstein. His son Rabbi Dovid Feinstein heads the Manhattan branch.
He was president of the Union of Orthodox Rabbis of the United States and Canada and chaired the Moetzes Gedolei HaTorah of Agudath Israel of America from the 1960s until his death. Rabbi Feinstein also took an active leadership role in Israel’s Chinuch Atzmai.
Rabbi Feinstein was revered by many as the Gadol Hador (greatest Torah sage of the generation), including by Rabbis Yaakov Yisrael Kanievsky, Yonasan Steif, Elyah Lopian, Aharon Kotler, Yaakov Kamenetsky, and Yosef Shalom Elyashiv, even though several of them were far older than he. Feinstein was also recognized by many as the preeminent Torah sage and Posek of his generation, and people from around the world called upon him to answer their most complicated Halachic questions.
Owing to his prominence as an adjudicator of Jewish law, Rabbi Feinstein was asked the most difficult questions, in which he issued a number of innovative and controversial decisions. Soon after arriving in the United States, he established a reputation for handling business and labor disputes. For instance, he wrote about strikes, seniority, and fair competition. Later, he served as the chief Halakhic authority for the Association of Orthodox Jewish Scientists, indicative of his expertise in Jewish medical ethics. In the medical arena, he opposed the early, unsuccessful heart transplants, although it is orally reported that in his later years he allowed a person to receive a heart transplant (-after the medical technique of preventing rejection was improved). On such matters, he often consulted with various scientific experts, including his son-in-law Rabbi Dr. Moshe David Tendler, who is a professor of biology and serves as a rosh yeshiva at Yeshiva University.
As a leader of American Orthodoxy, moreover, Rabbi Feinstein issued opinions that clearly distanced his community from Conservative and Reform Judaism. He faced intense opposition from Hasidic Orthodoxy on several controversial decisions, such as rulings on artificial insemination and mechitza. In the case of his position not to prohibit cigarette smoking, though he recommended against it and prohibited second-hand smoke, other Orthodox rabbinic authorities disagreed. It should be noted that all his detractors, while disagreeing with specific rulings, still considered him to be a leading and venerated sage. The first volume of his Igrot Moshe, a voluminous collection of his halachic decisions, was published in 1959. He made noteworthy decisions on the following topics:
- Artificial insemination from a non-Jewish donor (EH I:10,71, II:11, IV:32.5)
- Ascending the Temple Mount nowadays (OH II:113)
- Cosmetic surgery (HM II:66)
- Bat Mitzvah for girls (OH I:104 (1956), OH II:97 (1959), OH IV:36)
- Brain death as an indication of death under Jewish law (YD II:146,174, III:132, IV:54)
- Cholov Yisroel Permitted reliance on U.S. government agency supervision in ensuring that milk was reliably kosher, and it is as if Jews had personally witnessed it (YD I:47). This was a highly controversial ruling disputed by prominent peers of Feinstein.
- Cheating for the N.Y. Regents exams (HM II:30)[not in citation given]
- Classical music in religious settings (YD II:111)
- Commemorating the Holocaust, Yom ha-Shoah (YD IV:57.11)
- Conservative Judaism, including its clergy and schools (e.g., YD II:106–107)
- Donating blood for pay (HM I:103)
- Education of girls (e.g., YD II:109, YD II:113 YD III:87.2)
- End-of-life medical care
- Eruv projects in New York City
- Financial ethics (HM II:29))
- Hazardous medical operations
- Heart transplantation (YD 2:174.3)
- Labor union and related employment privileges (e.g., HM I:59)
- Mehitza (esp. OH I:39)
- Mixed-seating on a subway or other public transportation (EH II:14)
- Psychiatric care (YD II:57)
- Separation of conjoined twins who were fused all the way from the shoulder to the pelvis and shared one heart. It is during this case that C. Everett Koop said "The ethics and morals involved in this decision are too complex for me. I believe they are too complex for you as well. Therefore I referred it to an old rabbi on the Lower East Side of New York. He is a great scholar, a saintly individual. He knows how to answer such questions. When he tells me, I too will know."
- Shaking hands between men and women (OH I:113; EH I:56; EH IV:32)
- Smoking marijuana (YD III:35)
- Tay-Sachs fetus abortion, esp. in debate with Rabbi Eliezer Waldenberg
- Smoking cigarettes
- Veal raised in factory conditions (EH IV, 92:2)
- Permitted remarriage after Holocaust (EH I:44)

Rabbi Feinstein died on March 23, 1986 (13th of Adar II, 5746). It has been pointed out that the 5746th verse in the Torah reads, "And it came to pass after Moshe had finished writing down the words of this Torah in a book to the very end." (Deuteronomy 31:24). This is taken by some as a fitting epitaph for him.
At the time, he was regarded as Orthodoxy's foremost halkhic authority and Posek. His funeral in Israel was delayed by a day due to mechanical problems to the plane carrying his coffin, which had to return to New York. His funeral in Israel was said to be the largest among Jews since the Mishnaic era, with an estimated attendance of 300,000 people (though others since then may have been bigger. Some sources put Rabbi Ovadiah Yosef's funeral attendance at over 850,000). Among the eulogizers in America were Rabbis Yaakov Yitzchak Ruderman, Dovid Lifshitz, Shraga Moshe Kalmanowitz, Nisson Alpert, Moshe David Tendler, Michel Barenbaum and Mordecai Tendler and the Satmar Rebbe. The son of the deceased, Rabbi Reuven, also spoke.
In Israel, Rabbis Elazar Shach, Dovid Povarsky, Yitzchak Yaakov Weiss, Yehuda Tzadka, Rabbi Feinstein's son Reuven, and Rabbi Feinstein's nephew Rabbi Michel Feinstein, all tearfully expressed grief over what they termed a massive loss to the generation.
Rabbi Feinstein was held in such great esteem that Rabbi Shlomo Zalman Auerbach, who was himself regarded as a Torah giant, Talmid Chacham and posek, refused to eulogize him, saying "Who am I to eulogize him? I studied his sefarim; I was his talmid (student)."
R' Moshe was buried on Har HaMenuchot in proximity to his teacher, Rabbi Isser Zalman Meltzer; his friend, Rabbi Aharon Kotler; his son-in-law Rabbi Moshe Shisgal, the Brisker Rav, Rav Avraham Yofen, and next to the Belzer Rebbe.
Rabbi Feinstein invested much time molding select students to become leaders in Rabbinics and Halacha. Those students, over the years, spent countless hours a day serving as apprentices to their great Rabbi. Most are considered authorities in many areas of practical Halacha and Rabbinic and Talmudic academics. Some of those students are:
- Rabbi Nisson Alpert (1927-1986), Rav of Agudath Israel of Long Island, New York
- Rabbi Avrohom Blumenkrantz (1944-2007), author of The Laws of Pesach
- Rabbi Elimelech Bluth (Brooklyn, NY)
- Rabbi Shimon Eider (d. 2007), posek and author (Lakewood, NJ)
- Rabbi Dovid Feinstein (b. 1929), Rosh yeshiva of Mesivtha Tifereth Jerusalem in New York City, his son
- Rabbi Reuven Feinstein (b. 1937), Rosh yeshiva of Yeshiva of Staten Island, New York, his son
- Rabbi Aaron Felder (d. 2014), dayan (Philadelphia, PA)
- Rabbi Shlomo Frankel (Forshay, NY)
- Rabbi Shmuel Fuerst, Dayan of Chicago Rabbinical Council
- Chaim Ganzweig (Brooklyn, NY)
- Daniel Levy (Zurich, Switzerland)
- Jackie Mason, comedian (New York City)
- Rabbi Shmuel Niman (Queens, NY)
- Rabbi Michal Shurkin, Rosh Yeshiva Toras Moshe, Jerusalem, Author Hararei Kedem and Meged Givos Olam
- Rabbi Moshe Dovid Tendler, (Monsey, NY), his son-in-law
- Rabbi Mordecai Tendler, (New Hempstead, NY), his grandson
- Rabbi Moshe Meir Weiss, Rav of Agudath Israel of Staten Island, New York
Rabbi Feinstein's greatest renown came from a lifetime of responding to halachic queries posed by Jews in America and worldwide. He authored approximately 2,000 responsa on a wide range of issues affecting Jewish practice in the modern era. Some responsa can also be found in his Talmudic commentary (Dibrot Moshe), some circulate informally, and 1,883 responsa were published in Igrot Moshe. Among Rabbi Feinstein's works:
- Igrot Moshe; (Epistles of Moshe); pronounced Igros Moshe by Yiddish speakers such as Rabbi Feinstein himself; a classic work of Halachic responsa. Consisting of 7 volumes published during his lifetime and considered necessary for every Rabbi to have. Of these, the final, seventh volume was published in two different forms, the resulting variations found in a total of 65 responsa. An additional 2 volumes were published posthumously from manuscripts.
- Dibrot Moshe (Moshe's Words); pronounced Dibros Moshe by Yiddish speakers such as Rabbi Feinstein himself; a 14 volume work of Talmudic novellae with additional volumes being published by the Feinstein Foundation and being coordinated by his grandson, Rabbi Mordecai Tendler.
- Darash Moshe (Moshe Expounds, a reference to Leviticus 10:16), a volume of novellae on the weekly synagogue Torah reading (published posthumously). [Artscroll subsequently translated this as a two-volume English work.]
Some of Rabbi Feinstein's early works, including a commentary on the Talmud Yerushalmi, were lost in Communist Russia, though his first writings are being prepared for publication by the Feinstein Foundation.
