Prominent German rabbi resigns from leadership roles as report confirms allegations against him

BERLIN (JTA) – In a landmark step, investigators commissioned by Germany’s main Jewish organization have concluded that abuse of power and sexual harassment did occur at Germany’s liberal rabbinical seminary — and some of it, they say, may have crossed the line into illegality.

The 44-page “executive summary” of an investigation initiated by the Central Council of Jews in Germany is the latest and most damning report about the leadership of Rabbi Walter Homolka since accusations against him broke into public view last May.

Issued Wednesday after tense public conflict between the council and Homolka’s attorneys, the report concludes that structural changes are required to set Germany’s liberal rabbinical seminary, known as Abraham Geiger College, and other related Jewish institutions on the correct footing.

“A significant cause for the emergence of the problems identified by the investigators at the institutions under investigation is the personal misconduct of Rabbi Prof. Dr. Homolka in his function as a leader or person with great influence, which the investigators are convinced of,” the investigators wrote in their report.

Homolka announced Monday that he would withdraw from all functions in the seminary that he and a German-born American rabbi named Walter Jacob, founded in 1999. He also dropped out of the running on Tuesday for another term as chair of the Union of Progressive Jews in Germany.

A more comprehensive report including details about incidents in which investigators concluded that Homolka and his husband engaged in misconduct is due out in January, according to the Cologne-based law firm Gercke Wollschläger.

The preliminary report was welcomed in a joint statement by the Central Council, the German Interior Ministry and the Brandenburg State Ministry of Science, Research and Culture, which said they would “continue to fund the Abraham Geiger College to the same extent as before until the structural new beginning has been completed.”

It was also greeted with relief by the rabbinical student whose complaints kicked off the scandal.

“I think the report and the subsequent documents are a blessed development,” Itamar Cohen told the Jewish Telegraphic Agency. “It seems to confirm many suspicions which I and others share. It does affirm that I did the right thing and [this] could be the beginning of a new chapter of liberal Judaism in Germany.”

The scandal that erupted publicly in May began after Cohen sought help from Jonathan Schorsch, a professor at the School of Jewish Theology, in dealing with unsolicited pornographic material allegedly received from Homolka’s husband, who was also an employee at the seminary. (Abraham Geiger College is part of the School of Jewish Theology, which itself is under the auspices of the University of Potsdam.)

A German newspaper’s report about the allegations and an apparent effort to obscure them opened the floodgates for criticism of Homolka from past and current students, employees and colleagues. Homolka took a leave of absence from the numerous leadership roles he held with liberal Jewish religious and educational institutions that he had helped found since the late 1990s.

The scandal has shaken the foundations of modern liberal Judaism in Germany, and the new report suggests that those foundations were weak because they rested largely on one individual.

Josef Schuster, the president of the Central Council of German Jews, said the report made it clear that Homolka could not continue in his previous roles.

Homolka has rejected the allegations against him throughout, and his attorneys told German news media Wednesday that they believed the entire investigation was politically motivated. They accused Schuster of wanting to see Homolka exit Germany’s liberal Jewish leadership and said the Central Council had failed to consider fully the statement Homolka had given to investigators.

The report is the first to emerge from a third-party investigation into the allegations against Homolka. A separate investigation by the University of Potsdam, released in late October, found that some of the accusations regarding abuse of power to be justified, but did not find any criminally actionable behavior and thus confirmed Homolka’s ongoing employment there as professor. It did not investigate the sexual harassment accusations, as Homolka’s husband had left his job by then.

The new report did scrutinize those allegations. The investigators said they found 13 specific incidents involving allegations against Homolka’s husband. German libel law bars the publication of his name. Using what they called a “traffic light system,” the investigators classified nine of these incidents as “red” cases, in which 25 instances of misconduct could be identified. Two of these cases involved the “initial suspicion of a criminal offense,” they added.

Regarding allegations of abuse of power against Homolka himself, they found — after interviewing 73 individuals — a total of 45 concrete incidents, 14 of which they classified as “red,” involving a total of 23 instances of misconduct. A detailed account of those cases, including responses that Homolka delivered earlier this week, will be included in the final report in January, they said.

More broadly, they said, their interviews had illuminated a culture of misconduct in which unchecked, unlawful or arbitrary decisions could be made largely because of a consolidation of power under Homolka. He presided over an institution ruled by a “culture of fear,” the investigators found, leaving employees and students alike less likely to express criticism or concerns because of the possibility of reprisals.

The investigators said structural changes were needed if there was any hope of shifting the culture. “As long as institutions are in private hands or even in the hands of an individual, or at any rate within the essential sphere of influence of the person who, in the opinion of the investigators, practices and exemplifies misconduct himself, it is hardly conceivable that the causes of the deficits identified can be remedied,” their report says.

Cohen told JTA he wants to see “real change in the leadership” of all liberal Jewish institutions in Germany, and “an external compliance system set up.”

He said, “I hope to see the institutions Homolka founded take a life of their own, no strings attached.”

Anticipating the report, the Abraham Geiger College had announced its own restructuring plans on Monday, a day after ordaining four new rabbis and two cantors at a ceremony in Berlin.

In a statement, interim director Gabriele Thöne said a new foundation would become the provider of rabbinical training in Potsdam.

Further, Thöne said the “door is open to Zacharias Frankel College” — the Conservative movement seminary also under the umbrella of the School of Jewish Theology at the University of Potsdam —  “to join the new foundation on an equal basis while at the same time maintaining its independence.”

But in a scathing response issued Wednesday, the Conservative seminary said the Geiger College interim administration had not consulted them about the restructuring.

“A partnership between equal parties requires joint preparation, mutual trust, transparency and consensus. All this has been lacking so far, and continues to be lacking,” the statement said.

Signed by Rabbi Bradley Artson, dean of Zacharias Frankel College and the Ziegler School of Rabbinic Studies, the Conservative seminary in Los Angeles among others, the statement also said the preliminary report released Wednesday “confirmed the asymmetrical constellations of power in the two Potsdam rabbinical training colleges.”

Zacharias Frankel College  “was in a state of dependency on the will of one person from the time it was founded in 2013. Our institution was deliberately pushed into invisibility and excluded from communication with funders in Germany,” the statement read in part.

“From the outset, the project of a Masorti rabbinical training in Potsdam was merely a makeshift means of being able to found the School of Jewish Theology [also in 2013] and give it the appearance of representing several denominations, and thus of being pluralistically positioned. Instead, however, the accumulation of power led to a monopolization of non-Orthodox Judaism in one person” – namely, Homolka.

For their part, the government and Jewish funding organizations said in their statement Wednesday that they were “committed to ensuring that there will continue to be both liberal and conservative rabbinical training in Potsdam in the future,” but that the proposals developed so far at the Abraham Geiger College do not meet the requirement of being “a clear cut from the previous structure and a comprehensive new beginning.”

The release of the Central Council-commissioned report was preceded by a volley of statements by lawyers for both parties.

On Monday, the council’s attorneys announced that their preliminary report would come out in two days. On Tuesday, Homolka’s attorneys issued a statement criticizing the impending “sudden” release of the report’s summary, suggesting it reeked of “prejudgment.”

The law firm representing Homolka — Behm Becker Geßner — noted that its client had received “a list of questions with serious accusations” from the council’s attorneys, and that he had responded in writing last Sunday. “Should the result not take into account the meaningful statement of our client, there would be a massive violation of personality rights,” warned the lawyers, who have successfully battled some critical press coverage of Homolka.

The Central Council criticized what it called Homolka’s delay tactics, saying its attorneys had asked Homolka in early September if he would respond to questions but had not gotten any response to questions sent Oct. 19 until late Sunday night, well after multiple previous deadlines. Still, the council confirmed, its investigators would take Homolka’s responses into account.

“This tactic is the main reason why the law firm will not be able to complete the final and detailed report of the investigation by the end of the year,” the Central Council said. “The courage of the numerous victims must not be sacrificed to Homolka’s delay tactics.”

Meanwhile, the Union of Progressive Jews in Germany is to meet next week in Berlin, after a three-month postponement. Board elections will be held for the position of chair, previously held by Homolka.

On Nov. 26, that group published a report from an investigation that it had commissioned, which concluded that there was no proof of abuse of power at Abraham Geiger College.

On Wednesday, a critic within the body, the State Association of Jewish Communities of Lower Saxony, said the Central Council’s commissioned report “supports us in our demand for the resignation of Walter Homolka from all his offices within the Jewish community, which we already made in May.”

And there is dissent within the General Rabbinical Conference, Germany’s liberal rabbinical association, as well. About a dozen members issued a statement in November, breaking from the official, cautious tone, saying that “the abuse of power proven against Rabbi Prof. Dr. Homolka [in the university’s report of Oct. 26] is not compatible with the values of Jewish and general ethics.”

The association, known as ARK, issued a statement at the end of November stating that, despite differences of opinion in their ranks, they join the call for a structural and personal new beginning, as “a chance for the next phase of rabbinical training in Germany.”

Poll: Most New York City Jewish voters say criticism of Israel is often a cover for antisemitism

A majority of Jewish voters in New York City believe criticism of the Israeli government is often used as a cover for antisemitism, and more are concerned about antisemitic speech and attitudes than physical hate crimes, according to a new poll examining Jewish views on rising antisemitism and the city’s political climate. The survey also found that Jewish voters were more likely to blame the political left than the right for scapegoating Jews.

The Honan Strategy Group survey of 503 Jewish voters across the five boroughs, shared exclusively with the Forward, was conducted Oct. 2 through Oct. 6 via text-to-web before Mayor Zohran Mamdani’s controversial Oct. 7 statement and before his supporters turned on him during a peace vigil last Wednesday.

The survey found that while 85% do not consider criticism of the Israeli government or its leaders inherently antisemitic, 56% believe such criticism is often used as a cover for antisemitism. Meanwhile, seven in 10 Jewish voters believe they are being blamed for society’s problems, and more hold the political left responsible than the right.

The poll has a reported margin of error of plus or minus 4.3 percentage points.

The findings highlight the ongoing tensions between Mamdani and parts of the Jewish community over his harsh criticism of Israel, his defense of pro-Palestinian protesters’ rights and his ties to the Democratic Socialists of America and other left-wing groups.

Throughout his mayoral campaign and since taking office, Mamdani has sought to draw a line between his opposition to Israel and Zionism and his commitment to protecting Jewish New Yorkers. Last month, he rolled out a new municipal strategy to combat antisemitism, but the plan did not adopt a definition of the term.

Last Wednesday, on the third anniversary of the Oct. 7 Hamas attack on Israel, Mamdani issued a statement condemning Israel’s war in Gaza as a “genocide” and accusing the U.S. government of complicity in Israeli war crimes, irking Jewish leaders, including some allies.

The poll also found Jewish voters divided over whether some positions Mamdani has taken toward Israel are antisemitic. By 48% to 42%, respondents said describing Israel’s actions in Gaza as genocide is not antisemitic. Similarly, 49% said boycotting Israeli products and companies is not antisemitic, compared with 43% who said it is. But a majority — 52% — said denying Israel’s right to exist as a Jewish state is antisemitic. Almost two-thirds consider protesting outside synagogues an act of antisemitism.

Mamdani, who rose to power aligned with pro-Palestinian activism and is the city’s first Muslim mayor,  has repeatedly accused Israel of committing genocide in Gaza, has refused to recognize Israel specifically as a Jewish state and has called for a permanent end to city investments in Israel Bonds.

Mamdani has also defended the rights of anti-Israel protesters, including outside synagogues hosting events promoting real estate in Israel and the West Bank. Some demonstrations have included chants calling for an “intifada” and other rhetoric Jewish leaders described as antisemitic and intimidating, slogans Mamdani has either condemned or encouraged people not to use.

“The data shows broad consensus that criticism of Israel’s government is not antisemitic on its own,” pollster Bradley Honan told the Forward. “But it also shows that most Jewish voters have watched that criticism turn into something more troubling, and they want that line taken seriously.”

Earlier this year, the city’s top Jewish officials urged Mamdani to recognize Israel’s centrality to Jewish identity, and a group of liberal rabbis who met with the mayor warned Mamdani that his rhetoric on Israel is “causing harm.”

The same survey found widespread disapproval among Jewish voters of Mamdani’s handling of antisemitism.

Respondents also appeared to disagree with Mamdani’s approach to combating antisemitism. His plan includes millions of dollars for security, hate-crime prevention and Jewish education. It does not adopt a formal definition of antisemitism and offers little clarity on how the administration views anti-Zionism.

In the poll, 34% said antisemitic speech and attitudes were a bigger problem than physical hate crimes, such as assaults and vandalism. Just 8% said hate crimes were the bigger concern, while 46% considered both equally serious.

The photos may be black and white, but the klezmer world is drenched with color

In Lloyd Wolf’s evocative photography exhibit, “A Joyful Noise,” you can almost hear the Klezmer music — plaintive and celebratory, earthy and devout, and always with a profound, but not easily definable, outpouring of Yiddishkeit.

Now showing at the Dr. Bernard Heller Museum at New York’s Hebrew Union College, the 45 images feature solo, dual and group portraits of Klezmer musicians performing from the mid 90’s through 2024.

They may be at a wedding, in concert, or practicing alone in a bucolic setting. In one humorous picture, six Klezmer musicians emerge from a row of porta-potties, instruments in hand. Most of the pictures, arranged chronologically, are in black and white.

“The trick in photographing music, which is invisible, is that it has to be translated into a visible form,” said the Dayton, Ohio-born Wolf during a phone conversation from his home in Arlington, Virginia. “You have to pick up on the energy. It’s like jamming, only it’s silent. I’m often up on the stage with the musicians, right up in their faces. Because they know me they’re not posing. I can photograph bad musicians but the picture is much better if the musicians are great. It just raises the level of what you do.”

Wolf, who grew up hearing classical music, show tunes, folk, and Gilbert & Sullivan, has always loved music and musicians and he has photographed many, including Brian Wilson, Wynton Marsalis and The Grateful Dead.

The genesis of the exhibit was Wolf’s stunning book, A Joyful Noise! Klezmer in Motion.

“I’ve worked with Lloyd on several prior exhibits, mostly issue-oriented ones, and knew his work to be very good as well as interesting,” said Nancy Mantel, the exhibit’s curator. “Anything happy at this time seems like a win. And it’s about music and memories — also good.”

“It was the perfect moment to present our exhibition to celebrate nearly four decades of a vital musical genre that has immeasurably enriched Jewish life,” added Jeanie Rosensaft, the museum’s director. “Klezmer has contributed greatly to the growing appreciation for Yiddish language and culture among younger generations.”

A way to engage with the world

Klezmer music emerged from the world of Ashkenazi Jews in pre-Holocaust Eastern and Central Europe. It has roots in both Hasidic rituals and the Jewish (and Romanian, Hungarian and Romani) folk music of the time. In the post- World War II years, Klezmer music largely disappeared, in part because it was a painful reminder of what had been lost. In the 80s and 90s, when ethnicity became cool, it enjoyed a renaissance that continues today.

According to Wolf, there are any number of reasons why young people are attracted to Klezmer, including the fact that it provides a way to celebrate and identify that feels authentic and fun.

“Most of their roots are in the Yiddish world of their immigrant ancestors from Eastern Europe,” he said. “Some of it perhaps has to do with political and cultural gaps that have grown between Diaspora Jews and what they see and feel going on regarding the policies and actions of the current Israeli government.”

Wolf’s favorite picture, and coincidentally mine as well, presents Klezmer musician Michael Winograd sporting a jaunty little hat and playing his clarinet on an otherwise empty Coney Island boardwalk against a backdrop of immobilized rides, the iconic roller coaster and parachute drop. All by itself, the setting brings to mind an old ethnic, Jewish New York fixed in time.

“There is an inherent energy in Coney Island and the architecture is coherent,” said Wolf. “It’s just fun to look at. As Duke Ellington said, ‘It don’t mean a thing if it ain’t got a swing.’ I took that picture because Mike said he needed a cover shot. It was a freezing day, but he took his coat off. I said, ‘start playing.’ It was winter and there were no people out. That made for a much better picture than if we had done it in the summer with all the people.”

When I asked him when he chooses to shoot in black and white as opposed to color, he explained that, while there is usually no set plan ahead of time, he generally prefers black and white, “for its simplicity. It takes it out of a specific time. It’s more abstract, more classic. If I want a picture to be of a specific time and place, I’ll shoot in color.”

Wolf calls himself a documentary photographer and says his aesthetic influences include Gordon Parks, Dorothea Lange and Weegee, whose work combines “meaningful artistry and committed documentary.”

Wolf is very much the social activist. His books depict such topics as the Vietnam Memorial, social diversity in Columbia Pike, and Jewish fathers and mothers.

He says his interest in Klezmer musicians and music was at once improbable and inevitable. But no one was more surprised than his mother, a Bronx-born daughter of Yiddish-speaking Eastern European immigrants who desired nothing more than to be a fully assimilated American woman devoid of any accent or rituals.

“She was shamed by her Christian neighbors into sending me to Hebrew School and I did have a Bar Mitzvah,” recalled Wolf. “But we were not observant.”

His father, a refugee from Nazi Germany was a proud German Jew, highly cultured, intellectual and accomplished. “A computer pioneer, he was the technical director for building the ARPANET, the system that evolved into the Internet,” Wolf said.

The Holocaust, indeed Jewish topics in general, were not discussed in Wolf’s home. A child of the 60s, Wolf came of age during anti-war protests, love-ins and Jimi Hendrix. He majored in political science at Goddard College, though he never had any real interest in pursuing that field as a carer, he said. “For me photography was the way to engage with the world.”

He earned his Masters in photography at Trinity College in Hartford where he started freelancing for local newspapers. One of his outlets was the B’nai B’rith Magazine, which marked a turning point in his life and career. An early assignment took him to Treblinka, Poland and Israel, where he met his father’s cousins who, like his father, were forced to flee their homes. But unlike his father they talked about the Holocaust.

“I learned from them, for the first time, what had happened,” he said. “When I came back home from Israel I started going to shul.”

A music beyond politics?

Wolf was first turned on to Klezmer music in 1992 when he was assigned to cover two of the new Klezmer revival groups: Kapelye and the Klezmatics.

“I met up with Kapelye at a rehearsal space in the Workman’s Circle building,” he wrote to me in an email. “I can’t recall any particular melody at this date but do remember being in awe of Adrienne Cooper’s deep, commanding, matronly voice and presence. The next night I was to meet a guy from the Klezmatics at the Bottom Line club, Frank London. Here was a Jew roughly of my generation, who fully expressed his passion and art in an explicitly ethnic context, and with great skill and brio. He and the other band members at the time delivered a masterfully exhilarating concert: Transcendent, beautiful, sweeping, a grand opening of the soul in sound.”

London played a central role at the exhibit’s festive opening night reception by leading a Klezmer concert, which was, London said, fueled by Wolf’s photography, but also by the other exhibit in the gallery — paintings that explored “Mothers, Prophets, Warriors: Women of the Bible.”

“Both Jewish, both joyous and we were part of the joyous noise,” London said. “Our music is celebratory. The musicians share a common language and repertory. Nobody had sheet music.”

Throughout the performance, which featured two clarinetists (including Winograd), Wolf was moving about and shooting away.

The audience seemed to be having a fine time. For much of the performance they silently emanated a collective satisfaction; midway through, an elderly woman moved to the back where, all by herself, she started dancing to the music.

Then, something else happened. A few women were up and dancing into the aisles. They held hands and moved around the chapel, swaying this way and that. Slowly others in the audience joined in — men and women, young and old, most able-bodied, some less so. Round and round they went.

“When people define Klezmer, they often talk about it as dance music,” said London. “Names of different tunes are often names of dances. Whenever we play this music in its unadulterated form it’s always to celebrate Yiddish Ashkenazi culture that is also universal. It is beyond politics.”

I don’t agree. For me, the wordless dancers exuded an unabashed, unapologetic and perhaps even defiant ethnic identification, joy and pride. It was a deeply moving and searing political statement.

After the concert, I went back to look at Wolf’s photographs. They worked wonderfully well all by themselves. Still, the music and dancing I had just witnessed shed a new, more complex light on the pictures. Either way, the images on the wall and those that I took from the recital lingered as I left the building and walked up Mercer Street back to the 8th Street subway station.

On Columbus Day, remember Abraham Zacuto, the Jewish astronomer history forgot

(JTA) — Every October, Christopher Columbus returns not only as history but as controversy. The voyages associated with his name transformed the world, but their legacy is inseparable from conquest, coercion and the destruction that followed European expansion.

Yet the same Iberian age also produced a quieter and far less controversial revolution: advances in astronomy, mathematics, cartography, instruments and practical navigation that made sustained oceanic voyaging possible. Its protagonists included scholars, translators, mapmakers, instrument makers and pilots whose names are far less familiar than those of the captains who commanded the ships.

Among them, one figure deserves particular remembrance on Columbus Day: Abraham Zacuto, a Jewish astronomer born in Salamanca around 1452. Zacuto belonged to the same Iberian world as Columbus, but experienced its monarchies very differently. In 1492, Columbus sailed west under the patronage of Ferdinand and Isabella. That same year, the Catholic monarchs ordered the Jews of their realms to convert or leave. Zacuto left Castile and continued his work in Portugal. The celebrated maritime discoveries and the expulsion of Iberian Jewry were therefore not distinct historical worlds; they unfolded under the same rulers, at the same moment, within the same culture of ambition, knowledge and power.

Zacuto stands out within that larger scientific story. He was a rabbi, astronomer, mathematician and historian whose astronomical work helped give oceanic navigation a new degree of precision and practicality. His contribution belongs not at the margins of the Age of Exploration but within the scientific infrastructure that made long-distance navigation increasingly systematic.

Around 1478, Zacuto completed his great Hebrew astronomical work, “Ha-Hibbur ha-Gadol,” the “Great Composition.” Working within a long scientific conversation that included Greek, Islamic, Jewish and Christian astronomy, he refined and organized astronomical calculations in forms of exceptional practical value.

After the expulsion from Spain, Zacuto entered Portugal at precisely the moment when the kingdom was pushing maritime exploration farther into the Atlantic and down the African coast. Zacuto’s pupil, José Vizinho, a Jewish adviser to Portuguese King John II, was associated with the practical Latin and Castilian presentation of Zacuto’s astronomical material. In 1496, Zacuto’s Almanach Perpetuum was printed at Leiria in four known issues – three with Latin preliminary matter and one with Castilian.

The importance of those tables was intensely practical. They supplied precise, ready-to-use values for the changing position of the sun through the year. For a pilot on the high seas in daylight, far from recognizable coastlines, this meant that a noon observation of the sun could be combined with solar-declination data to determine latitude — the ship’s north-south position. The difficult astronomical calculations had already been embodied in the tables. What remained aboard ship was an operational procedure: Observe the sun, consult the appropriate value and calculate latitude. That combination of precision and usability greatly facilitated daytime position-finding at sea. Solar tables derived from Zacuto’s work entered early Portuguese navigational manuals and became part of the practical scientific culture of oceanic travel.

The clearest measure of Zacuto’s importance may be what happened next. The Almanach did not remain a local Portuguese publication. Its tables were reprinted repeatedly in Venice in 1498, 1502, 1525 and 1528. A work first printed in Leiria moved into one of Europe’s great publishing centers and continued to circulate for decades. That publishing history alone tells us something about the standing Zacuto’s astronomy acquired.

Its reach extended farther still. Zacuto’s astronomical material was translated and adapted into Arabic. One Arabic version was produced, likely in Istanbul, in 1505-06; another, associated with Ahmad ibn Qasim al-Hajari in Morocco around 1624, survives in several manuscripts. The work of a Jewish astronomer writing in Hebrew in 15th-century Salamanca had crossed into Latin, Castilian and Arabic scientific cultures.

Zacuto’s name also became entwined with the memory of the great navigators. Accounts have long connected his tables with Columbus and Vasco da Gama, including the famous 1504 lunar eclipse in Jamaica. In this episode, Columbus intimidated Indigenous Jamaicans by predicting the disappearance of the moon, relying on Zacuto’s almanac, which he had on board. A manuscript connected with the Almanach also survives in Seville’s Biblioteca Colombina, the library created by Columbus’s son Hernando. Taken together, these associations reveal the stature Zacuto’s work acquired in the historical memory of the Age of Exploration.

Perhaps the most striking part of Zacuto’s story is what happened to the man himself. Portugal valued the kind of expertise he represented. Yet in December 1496, King Manuel I ordered Portugal’s Jews to leave unless they converted, and in 1497 the crown subjected the Jewish population to mass forced conversion. Zacuto left Portugal as well.

Exile did not end either his travels or his scholarship. From Portugal he moved through North Africa, including Tunis, before eventually reaching Jerusalem. There, late in life, he returned once more to the astronomical work that had made his name known across the Mediterranean, recalculating and updating his earlier tables for the Jewish calendar and the meridian of Jerusalem. The strongest recent reconstruction of his life places his death in Jerusalem in Tevet 5274, or late 1513 or very early 1514 — commonly given as 1514.

Zacuto’s story is therefore larger than a footnote to Columbus. It joins two strands of Sephardic history too often told apart: persecution and exile, and the transmission of knowledge, texts and technologies across borders.

Zacuto’s own tables and 15th-century procedures are now obsolete, but their underlying navigational logic endures. Modern celestial navigation still determines position by combining observations of the sun, moon, planets or stars with authoritative astronomical data. The U.S. Naval Academy requires all midshipmen to study navigation, and its current curriculum includes celestial navigation alongside electronic methods. The U.S. Naval Observatory still describes celestial navigation as a critical independent backup to GPS and other electronic systems. And the Nautical Almanac, first published in 1855, remains the standard U.S. Navy resource for marine celestial navigation. The instruments and calculations have changed, but the essential logic remains: Observe the heavens, consult reliable astronomical data and determine position.

Zacuto’s scientific reputation also survives in an unexpected place. In 1935, the International Astronomical Union formally adopted the name Zagut for a lunar crater honoring Abraham ben Shmuel Zacuto. Modern astronomy has, quite literally, written his name onto the Moon.

Columbus remains a household name because voyages leave dramatic images: ships, landfalls, encounters and conquest. The calculations, tables, instruments, translations and printed books that made such voyages possible are easier to forget. Remembering Zacuto widens the story: His tables brought greater precision and practicality to daytime navigation; his work crossed languages and continents; and his life traced the routes of Sephardic exile from Iberia to Jerusalem. The age of maritime discovery was also an age of scientific discovery, and some of the knowledge that carried Iberian ships across oceans was created by scholars whose communities those same monarchies expelled.
