Helen Hadassah Levinthal was born on April 22, 1910, into a distinguished, multi-generational rabbinic family whose prestige and communal responsibilities shaped her interest in studying Judaism at an advanced level and serving the Jewish community. Her father, Rabbi Israel Herbert Levinthal (1888–1982), was a leading Conservative rabbi and long‑time spiritual head of the Brooklyn Jewish Center, an institution remembered as a beacon of Jewish life in New York City and a magnet for large Friday‑evening crowds drawn by his sermons. He also taught homiletics at the Conservative movement’s Jewish Theological Seminary. He was a lifelong Zionist. Born in Vilna, he was a graduate of Columbia University and had a law degree from New York University. Her mother was May R. Bogandoff; May and Israel also had a son, Lazar.

 Lyon’s paternal grandfather, Rabbi Bernard [Dov Ariyeh] Louis Levinthal (1864–1952), was ordained in Lithuania by Rabbi Isaac Elchana Spektor, for whom the rabbinic program at Yeshiva University was named. He was one of the leading Orthodox rabbis in the United States for over 50 years but often worked across a broad spectrum of Jewish organizations. He served Congregation B’nai Abraham, Philadelphia’s largest Eastern European synagogue, from 1891 until his death. He played a major role in the founding of Yeshiva University (1896), the Orthodox Union (1898), the American Agudas Harabbanim (1901), and Mizrachi (1902), now the Religious Zionists of America. 

Despite her family’s visibility in the rabbinic world, after marrying Lester Lyons in 1939, Helen took his surname as her own. The couple had two children, Judith and George David. Lester was also active in Jewish communal life.

For Helen Lyons, her ancestors were not only a point of pride but a calling.  Having come of age at a time when American women had just won the right to vote, she developed the belief that Judaism could also become more gender inclusive. 

 As a child, Lyons received an unusually strong Jewish education for a girl of her era.She received private Jewish instruction in Hebrew, becoming fluent enough to read classical texts, including Tanakhn and rabbinic literature, in the original language. Lyons then attended  New York’s Hunter College, where she received a strong secular education, including literature, history, and languages. 

Following her college graduation, Lyons enrolled at the Jewish Institute of Religion (JIR), then a non-denominational seminary  founded by Rabbi Stephen S. Wise. Her family strongly supported her decision. Her father publicly defended her studies, advocated for women's religious education, and allowed and encouraged her to pursue rabbinical training. Lyons  was an excellent student at JIR, which championed critical study, Jewish peoplehood, and public engagement yet remained bound by the era’s assumptions about women’s formal authority. 

Several other women, including Irma Levy Lindheim and Dora Askowith, who had earned a PhD at Columbia University, had enrolled at JIR prior to Lyons. Previously, both Hebrew Union College (the Reform movement’s seminary) and the Jewish Theological Seminary had also had women enroll in their schools but failed to ordain them. In the 1890s, Rachel “Ray” Frank, had served as an itinerant preacher or proto-rabbi particularly on the West Coast. Although JIR officially changed its charter in 1923, in response to efforts by Irma Lindheim,to include the possibility of ordaining women, none of its female students prior to Levinthal had completed the full course of study required to be a rabbi. It was Levinthal’s persistence that brought the question of rabbinic ordination for women to the fore. 

Levinthal’s scholarly ability was demonstrated in her 125-page thesis, “Woman Suffrage from the The legal corpus of Jewish laws and observances as prescribed in the Torah and interpreted by rabbinic authorities, beginning with those of the Mishnah and Talmud.Halachic Aspect,” submitted to the Department of Talmud in 1939. Her erudite work was grounded in the study of contemporary Hebrew-language Halakhic decisions written by rabbinic authories in response to questions posed to them.responsa on the issue of female Jewish suffrage in British Palestine. Beginning with a feminist overview of women’s religious life in Ancient Israel, she explored both Lit. "teaching," "study," or "learning." A compilation of the commentary and discussions of the amora'im on the Mishnah. When not specified, "Talmud" refers to the Babylonian Talmud.Talmudic and post-Talmudic sources before delving into the debate about the place of women in the Old and New Jewish community in Palestine prior to the establishment of the State of Israel. "Old Yishuv" refers to the Jewish community prior to 1882; "New Yishuv" to that following 1882.Yishuv. Interestingly, she did not directly address the issue of the ordination of women but rather argued that accommodation to modernity had compelled all but the most intransigent of Orthodox groups to reevaluate the role of women in the new national Jewish community in Palestine. Given her acumen in dealing with rabbinic texts and thoughts, it is not difficult to imagine that Levinthal was anticipating a halakhic debate over the ordination of women and how a theoretical framework respectful of tradition could be constructed in favor of granting women the title of rabbi. 

A decade earlier, Regina Jonas had already argued directly for the ordination of women in her 1930 thesis at the progressive rabbinic school in Berlin, from which she received a teaching degree. In 1935, Jonas was privately awarded the title of rabbi by Max Dieneman. Two years later she was permitted to offer pastoral services to the Jews of Berlin. As the situation in Germany worsened, she was allowed to broaden her rabbinic activity. In 1942 Jonas and her mother were deported to Theresienstadt; Rabbi Jonas died in Auschwitz in October 1944. It is unlikely that Levinthal was aware of Jonas’ academic work or demise. 

Meanwhile, in 1939 at JIR’s commencement, the nine men in Levinthal’s class were ordained while Levinthal only received a Master of Hebrew Literature (MHL) degree and a certificate recognizing her academic accomplishments. Several newspapers, Jewish and general, ran stories on JIR’s decision not to ordain Levinthal. The school’s president declared “the time was not ripe for the JIR to ordain women” (Wise 1939). Indeed, it would take over three more decades before an American rabbinical school was willing to cross Judaism’s most significant gender line, when Hebrew Union College ordained Sally Priesand in 1972. 

JIR’s failure to ordain Levinthal made the limits of institutional policy especially visible. In March 1939, even before her graduation, her father invited her to preach in his synagogue; she delivered a sermon on the theme “The Jewish Woman Faces a New World.” That invitation functioned as both familial recognition and communal endorsement. It placed her in a prestigious pulpit, an event rare for women in her time, and signaled that her learning was not merely private or academic but a public statement about her ability to serve as a rabbi. That year, Lyons was also invited to speak on the topic of “The Future of Judaism” to a crowd of 900 people at a Brooklyn auditorium. 

Press accounts reported on other speaking engagements before large audiences, including a widely reported address titled “The Future of Judaism” in 1939 at JIR. Time magazine described her pulpit appearances as “as near to being a rabbi as a female might be,” emphasizing the paradox her life embodied: public rabbinic function absent rabbinic title (Time, “Religion First”). In 1940, Brooklyn’s B’nai Shalom congregation invited Lyons to preach during the High Holy Days; her appearance was covered by Time magazine. 

Not long after, Levinthal was selected by the Jewish Center Lecture Bureau along with Judith Kaplan (the eldest daughter of Rabbi Mordecai Kaplan and the first American woman to have a Lit. "daughter of the commandment." A girl who has reached legal-religious maturity and is now obligated to fulfill the commandmentsbat mitzvah ceremony), and Avis Clamitz  Shulman, who had studied at the Hebrew Union College, to lecture nationally on Jewish subjects. The lecture circuit positioned her as a public educator on a national scale, extending her impact beyond New York City, and gave her a significant place  in the world of American Jewish adult education. Thereafter, Hadassah, the leading women’s Zionist organization in America, provided Levinthal and other women with a platform to continue as leaders in the Jewish community, thereby paving the path to the ordination of women. 

Ultimately, Lyons gave up the role of a religious pioneer. With limited professional Jewish roles available, she followed the dominant postwar pattern for educated women, settling into a life of a wife, mother, and organizational leader in the years following World War II. 

In 1988, a year before her death of a brain tumor in New Rochelle, New York, on August 13, 1989, the Hebrew Union College–Jewish Institute of Religion issued Lyons a special certificate of recognition—a belated acknowledgment that she had completed rabbinic training at a level equivalent to her male peer. In 2022, on the fiftieth anniversary of Sally Priesand’s ordination, Lyons was featured in a Hadassah magazine article for her pioneering role in American Jewish women’s religious history. A camp scholarship was set up by her husband in her memory. Today, Helen Hadassah Levinthal Lyons is remembered as one of the “would be” rabbis who served as a pioneer in the history of American Judaism.
