 Rabbi Dovid Feinstein led the Mesivtha Tiferes Yerushalayim yeshiva on the Lower East Side for decades, succeeding his late father. 

(JTA) — Rabbi Dovid Feinstein, one of the most prominent haredi Orthodox rabbis in the United States, has died. He was 91 years old.

The son of Rabbi Moshe Feinstein, one of the preeminent Jewish legal authorities in the United States for much of the 20th century, Feinstein served as the head of the Mesivtha Tiferes Yerushalayim on Manhattan’s Lower East Side from the time of his father’s death in 1986 until his own passing on Friday. He also served on the Moetzes Gedolei Hatorah, the rabbinical council connected to Agudath Israel, an umbrella organization representing haredi, or ultra-Orthodox, communities.

Though the Orthodox community on the Lower East Side has shrunk over the years as Orthodox communities in Brooklyn and other cities became more prominent, Feinstein continued to be a sought-out Jewish legal authority. 

“He was a dyed-in-the-wool East Sider. He was very much a man of the neighborhood,” said Jonathan Boyarin, a professor of Jewish studies at Cornell University.

Boyarin spent a year studying at Feinstein’s yeshiva and chronicled the place in his recent book, “Yeshiva Days: Learning on the Lower East Side.”

Feinstein was born in Luban, which was then part of Russia and now Belarus, and came to the United States as a child in the 1930s. His father became head of the yeshiva at Mesivtha Tiferes Yerushalayim when the Lower East Side was a center of Jewish life in New York City, bringing together Orthodoxy, Yiddish secularism and radical Jewish politics in one cramped neighborhood. The elder Feinstein was considered one of the foremost Jewish legal experts and a communal leader in the United States until his death.

After his father died, Feinstein took over as head of the yeshiva. By that time, the Jewish community of the Lower East Side had already begun to decline, though it remained a draw for those shopping for Jewish food and books. Over time, though, the community dwindled further as large Orthodox families decamped for more spacious parts of the city or to newer communities in New Jersey.

Today the yeshiva has an outpost on Staten Island in addition to the Lower East Side building, and many students travel to study at the yeshiva from their homes in larger Orthodox communities elsewhere in the city or New Jersey.

Orthodox organizations mourned Feinstein’s death.

“There are no words. We are reeling,” Rabbi Chaim Dovid Zwiebel, executive vice president of Agudath Israel, said in a statement. “Rabbi Feinstein was a true ‘manhig hador,’ leader of our generation, and ‘posek hador,’ halachic authority for the generation. The entire Jewish world has suffered a terrible blow with his death.”

The Orthodox Union also issued a statement.

“In addition to assuming his father’s role as head of the yeshiva, Rav Dovid was relied upon by the Torah community to succeed his father as a preeminent source of Halachic wisdom,” the O.U. said. “He provided a clear, steady and confident voice of Halachic guidance to innumerable individuals and institutions within the community.”
