New book looks at the fight by law-abiding Jews to rein in the New York Jewish underworld in early 20th century
The Incorruptibles: A True Story of Kingpins, Crime Busters, and the Birth of the American Underworld
Reviewed by BERNIE BELLAN For those readers who can remember the story of “The Untouchables,” the crime-fighting unit led by Elliot Ness, which was established by the Bureau of Prohibition in the US in the 1930s, tales of shoot-outs between courageous crime-fighting “good guys” and villainous underworld bootleggers and other assorted criminals would probably be thought of as something that wouldn’t have its origin in a Jewish-led crime-fighting unit established several years earlier.

But, would you believe that not too many years before the often bloody events that were depicted in “The Untouchables” came to pass there was another organization in New York City – led by Jewish crime fighters at that time, which had a somewhat tacit affiliation with the New York City Police Department, and whose purpose was to wage war on Jewish criminals on New York’s East Side? That organization was known as “The Incorruptibles” and the story how it came to be created is told in a fascinating new book, titled “The Incorruptibles: A True Story of Kingpins, Crime Busters, and the Birth of the American Underworld,” written by a New York crime reporter by the name of Dan Slater.
As someone who has long had a fascination with shady Jewish characters, I’ve come to realize over the years that a rollicking good story of a Jewish mobster, such as the close friendship a former Winnipegger by the name of Al Smiley had with the notorious Bugsy Siegel, about which Martin Zeilig wrote for The Jewish Post & News in March 2017, resonates with readers in ways that stories about more righteous Jews don’t.
While Martin’s story about Al Smiley was by no means the first story we’ve ever had about Jewish mobsters, a quick search of our online archive would lead you to numerous stories about Jewish gangsters and other assorted criminals.
In the summer of 2023 we ran two stories in relatively rapid succession that elicited a higher than usual amount of interest from readers. One was my review of a book called “Jukebox Empire,” about someone by the name of Wilf Rabin, who actually grew up in Morden, Manitoba. The other story was about bootlegger Bill Wolchock, written by Bill Redekopp, and which appeared in our 2023 Rosh Hashanah edition. Later, when I posted that story to our website it received so many views that I’ve returned it to our home page twice since. (You can now read that story if you missed it by reading it here: “Booze, Glorious Booze”
All this serves as a preamble to my review of “The Incorruptibles.” I have to couch what I’m about to write with an admission: As a youngster growing up in a sheltered environment, and attending the Talmud Torah, where all we were ever told about was Jewish “heroes,” and the only villains were Jews who didn’t lead properly observant lives, reading “The Incorruptibles” came as a real shock to my conception of how much Jews could be associated with the most sordid type of criminal activity.
It’s one thing to realize that many Jews were involved with bootlegging – something that has developed an almost romantic connotation over the years through books, movies and television programs, but to learn that in the latter part of the 19th century Jews in New York were in control of that city’s: prostitution (and most prostitutes were Jewish!); drugs (however, with the understanding that drugs, including heroin and cocaine, were legally available in the U.S. until 1907 and could be readily purchased in pharmacies); gambling; and protection rackets – does come as somewhat of a shock to a sheltered Winnipeg Jew.
Dan Slater’s depiction of life in New York City at the turn of the 20th century is unremittingly harrowing. For the first part of the 20th century the lower East Side of New York was the most densely populated area on Earth. Housing conditions were horrible and the hundreds of thousands of new immigrants arriving yearly – beginning in the 1870s, from what was known as the Pale of Settlement in Eastern Europe – fleeing persecution and pogroms, found themselves being shunted into unspeakably barbaric working conditions in lower East Side factories, predominantly garment factories – owned by fellow Jews. (The author actually spends a considerable amount of time explaining how exactly the Pale of Settlement came into being and how sudden and incredibly violent wholesale persecution of hundreds of thousands of Jews could happen almost overnight – with the death of a particular czar, for instance.)
It was amidst this churning cesspool of a city that Jewish criminal activity of all sorts ran rampant. Two images from “The Incorruptibles” in particular haunted me. One was Slater’s explanation how so many young Russian Jewish women – most in their early or mid-teens, and only recently arrived in New York, were forced into prostitution. Many of these young women would go to a dance – looking to find some relief from the slave-like conditions that permeated the factories in which they worked. While at the dance, they would be approached by a young Jewish man who would offer them a drink. These guys, known in the colloquial as “Alphonses,” or, in Yiddish, as “schimchas,” would lace the girls’ drinks with drugs (a common occurrence to this day) and take the girls home, where they would rape them. But – now defiled, the girl could not possibly return to her family home out of shame; thus, tens of thousands of young Jewish women were forced into prostitution.
The other image that haunts me was the widespread practice of “horse poisoning.” Protection rackets have probably been around from time immemorial, but in this particular incarnation, criminals would confront business owners with a choice: Pay for “protection” or see your means of transportation (and remember, this was at a time when a horse-drawn buggy or carriage was the principal means of transportation) poisoned.
(There is actually a photo in “The Incorruptibles” of a horse lying dead on a New York street after it had been poisoned. Apparently it happened on a regular basis to the point where it didn’t draw much attention.)

While the book chronicles one sordid story after another so that the reader can understand just how tough life was on the lower East Side – often with reference to the colourful names of some of the most famous Jewish thugs who terrorized their fellow Jews, such as “Bald Jack Rose” or “Big Jack Zelig” (no relation to Martin Zelig – I checked), the biggest mobster of them all was the legendary Arnold Rothstein.
Rothstein is undoubtedly most famous for reputedly having fixed the 1919 World Series by bribing eight members of the Chicago White Sox, the overwhelming favourite to defeat the Cincinnati Reds, to throw the series. (It has never been proven absolutely conclusively that Rothstein did that, but as “The Incorruptibles” explains, the evidence points overwhelmingly in his direction.)
Rothstein was the kind of gambler who could lose $350,000 in a single night of playing poker – and not worry about it.
Here is an example of Slater’s ability to describe a character, when he sums up Arnold Rothstein: “Picture in one individual a sentimental and tender lover, a genial and humorous companion, a charitable giver, a loyal friend—and—a wholesale drug dealer, a crooked sports fixer, a welching gambler, a stolen securities fence, a rum-ring mastermind, a corrupter of police, a grafter through politics, a gunman, a judge-briber, a jury-tamperer, a blackmailer, a pool shark, a swindler.”

But, up against the villains of “The Incorruptibles,” Slater also depicts the stories of two very talented – and brave, young Jewish men, who were willing to challenge the criminal class: A lawyer by the name of Harry Newburger and Abe Shoenfeld, the son of a well-known New York reformer by the name of Mayer Shoenfeld.
As Slater explains, it was only when members of New York’s largely German-Jewish upper class began to take note of the horrid conditions in which the vast majority of the Eastern European Jews who had recently immigrated to America were living did an impetus to try and change things develop. Two men, Jacob Schiff (who is described as the J.P. Morgan of his day in terms of his vast wealth), and Felix Warburg, together with the rabbi of the leading temple of its day, Rabbi Judah Magnes of Temple Immanu-El, organized a group known as the “Kehilah.”
The Kehilah mandated Newburger and Shoenfeld to do whatever they deemed necessary to begin cleaning up the lower East Side. Of course, given how corrupt New York officials were at the time – under the control of the notorious Tammany Hall, led by “Big Jim Sullivan,” most of the New York City Police Department was also thoroughly under the control of criminals, which made the challenge set out for Newburger and Shoenfeld all the more difficult.
The book describes, sometimes in painful detail, the difficulties faced by the group assembled by Newburger and Shoenfeld, known, naturally, as “The Incorruptibles.” They weren’t above busting heads themselves, it turns out.
Again, one of the more interesting aspects of history to emerge from this book is that men would often switch sides at the drop of a hat – to go from violently attacking one particular group – at the behest of this or that mobster, to attacking the same group they were supposed to be defending the next day.
As has already been noted, the garment trade played a pivotal role in the development of New York City into becoming not only a magnet for immigrants, it also also played a prominent role in New York’s becoming the vast economic powerhouse that it is today. Slater notes that, at one point, 80 percent of all garments produced in the U.S. came from the lower East Side.
As workers began to organize themselves into unions, garment factory owners hired thugs, known as “shtarkers” (strong men) to beat up workers, occasionally to kill union organizers. In time though, the tide began to turn and, as unions gathered strength, the same tactics of violence and intimidation that had been used against workers began to be employed by unions – with workers who dared to cross picket lines (known colloquially as “scabs”) often being on the receiving end of that violence, occasionally ending with them being killed.
Newburger and Shoenfeld were thrust into the midst of this turmoil, trying to bring some peace to the labour disputes. Ironically, Mayer Shoenfeld (Abe’s father) was a longtime advocate for workers’ rights, but he would not talk to his son, who tried to straddle both worlds – of employers and employees.
“The Incorruptibles” describes the many battles fought to rein in the gambling, prostitution, protection rackets, and what became the illegal drug trade that were part and parcel of life on New York’s East Side. As the years went by, the Jewish dominance of the New York underworld gave way to the ascendance of the Italian mob. (Slater also acknowledges the roles that other groups also played in New York criminal activity, including the Irish), but his main focus is on Jewish criminals.
“The Incorruptibles” is a long and detailed book, drawing upon a great many different sources, and at times, the proliferation of names entering the scene can be more than a little confusing. But, for anyone who has an interest in reading something that peels back the layers of a very disturbing aspect of Jewish history that might not fit all that well with the notion of Jewish righteousness, then “The Incorruptibles” might be of interest.

Winnipeg’s Jewish Community and the Question of Online Casino Bonuses: What Manitoba Players Should Know
A reader wrote in last month asking a simple question: is it legal to play online casino games in Manitoba, and if so, what’s actually a fair deal? It’s the kind of practical, money-conscious question this paper’s readers tend to ask before spending anything, the same instinct that shapes how the community shops, budgets for the High Holidays, or decides which shul renovation appeal to support. Manitoba’s online gambling landscape has changed enough in the last few years that the old assumptions no longer hold, and it’s worth walking through what’s actually there now.
Manitoba’s Online Casino Landscape in 2026
Manitoba doesn’t have an open, competitive online casino market the way Ontario does. Since April 2022, Ontario has allowed private operators to apply for licences and compete for players directly. Manitoba still runs a single-operator model: Manitoba Liquor & Lotteries (MLL), the Crown corporation that also runs the province’s Liquor Marts and lottery products, operates the one legal online casino for Manitoba residents, PlayNow.com. That’s the whole regulated market in this province. Outside that single option, Manitobans who search for online casinos will find dozens of sites willing to take their money and their information, a pattern this paper’s own Local/Canadian News coverage has tracked as provinces across the country adjust their approach to regulated gambling. Some are licensed elsewhere, Malta, Curaçao, the UK, and operate in a legal grey zone for Canadian players; enforcement against them has been inconsistent for years. None of them answers to Manitoba’s regulator, and none of them contributes a dollar back to this province.
How Casino Welcome Bonuses Are Structured and Regulated
A welcome bonus is usually presented as free money: deposit $50, get $50 in bonus funds, sometimes with free spins attached. What matters is the fine print attached to it. Wagering requirements determine how many times you must play through the bonus amount before you can withdraw any winnings; a 30x requirement on a $50 bonus means $1,500 in total wagering before that money is really yours. Game weighting matters too: slots typically count 100% toward that requirement, table games often count 10% or less, which punishes anyone who prefers blackjack over slot spins. Time limits, usually 7 to 30 days, and maximum bet sizes while a bonus is active, round out the list of terms most players skip past. On PlayNow.com, these terms are published in plain language and reviewed by a provincial Crown corporation with community accountability baked into its mandate, the same mandate that funds Manitoba’s healthcare and education budgets. That’s a meaningfully different relationship than the one an offshore site has with a Manitoba customer.
The Difference Between Licensed Canadian Operators and Offshore Alternatives
This is where the practical stakes are highest. A licensed Canadian platform is subject to specific consumer protections: verified game fairness, dispute resolution through a regulator you can actually reach, and deposit-limit tools that work. An offshore operator answers to a foreign licensing body, if it answers to anyone at all. Winnipeggers who’ve had a withdrawal disputed by an offshore casino know how limited the recourse actually is; there’s no Manitoba office to call and no local regulator with jurisdiction. Across the country, players comparing regulated options increasingly start by checking a best casino bonus Canada comparison rather than relying on whichever ad appears first. It’s a reasonable way to sort a legitimate Canadian-licensed platform from an offshore look-alike before depositing anything.
Responsible Gambling Resources Available in Manitoba
This part matters more than the bonus terms. MLL runs Informed Gambling, its dedicated responsible-gambling program, which includes deposit and time-limit tools, self-exclusion options, and educational material aimed at helping players recognize when a habit has become a problem before it becomes a crisis. Manitobans concerned about their own gambling, or a family member’s, can call the Manitoba Addictions Helpline, toll-free at 1-855-662-6605, for confidential support. Shared Health, formerly the Addictions Foundation of Manitoba, also provides professional counselling free of charge to anyone who needs it, regardless of ability to pay. For a community that has always taken care of its own, through the Chesed Shel Emes, through synagogue-run support networks, through the kind of quiet checking-in that happens after a funeral or a hard year, these resources are worth knowing before they’re needed, not after. Chasing a Canadian online casino bonus isn’t worth it if the wagering requirements are already causing strain. That’s a conversation worth having, honestly, inside families and inside the community, before it becomes a private one.
Where to Compare Current Casino Bonus Offers Across Licensed Platforms
None of this is an argument against playing. It’s an argument for playing somewhere accountable, with terms you understand, and for a modest amount you’ve already decided you can afford to lose. Manitoba’s single-operator model makes that comparison simpler than Ontario’s crowded market, but it also means doing the homework on wagering requirements and licensing status matters just as much, if not more, when there’s only one legal option and a long list of unregulated ones competing for the same click. Ask the question before depositing, not after; that’s the same advice this community gives about most things worth being careful with.

Embracing your femininity in Tishrei
By ELENA KNIGHT Rosh Chodesh Sameach! This month, Tishrei, is a time of beginnings; we observe Rosh Hashanah, Yom Kippur, Sukkot, Shemini Atzeret, and Simchat Torah, we celebrate humanity’s creation, and we celebrate the seventh month since the Exodus from Egypt with shofar and festivities.
Though all Jewish people celebrate the head of the month, traditionally, women are rewarded for not participating in the sin of the Golden Calf, and many women take the day to honour the Shechinah, the feminine mystical aspect of the divine. Literally meaning “dwelling,” the Shechinah relates to G-d’s close and relational presence amongst people, such as in the Temple. In Kabbalah, since the word is grammatically feminine, the Shechinah is seen as the feminine aspect of G-d, representing a nurturing, compassionate presence, an almost motherly form of the divine. But how can we honour the Shechinah specific to Tishrei?
Rosh Hashanah provides a straightforward answer: New Year’s resolutions. A tradition observed across the globe, by people of all traditions and faiths, we can apply the idea to our New Year, and think of ways to improve in the year 5787. Make a resolution to join a women’s group at your synagogue or JCC, support woman-owned businesses (the SHE-Canada directory can help you find them!), read up on feminist theory or history, or mentor a young girl in your community. And, like traditional resolutions, don’t kick yourself if you slip up!
While we listen to the shofar, recall that its sound awakens the soul, mystically preparing us all for the Shechinah’s manifest presence on Yom Kippur, when it comes to earth to bring realignment and forgiveness.
Yom Kippur, the Day of Atonement, also offers a way to embrace your feminine side. On this day, we are prohibited from all work, and physical pleasures; though it may sound counter-intuitive, this is the perfect day to be aware of your womanhood in its most natural state. No adornments, no makeup, no perfume, no fancy shoes, no gold jewelry. This is a day when we can see who we are without the extras, as G-d made us, and be aware of the beauty in our creation as is. Also, for any women who are pregnant, nursing, or otherwise exempt from the holiday restrictions, isn’t it amazing to know that our Creator values our health over all?
Sukkot offers a time to appreciate the bounty that G-d has provided over the past year, but what I want to call attention to is the Four Kinds. The etrog has both taste and aroma, the lulav’s fruit, the date, has taste but no aroma, the hadas has aroma but no taste, and the aravah has no taste nor aroma; at some point in our life, and likely at some point in the month, we are all like one of the Four Kinds. The Midrash drew a comparison between taste and Torah learning and between aroma and good deeds. Sometimes, we have etrog moments, when we have a perfect balance between learning and doing, we are in harmony. Sometimes, we have lulav moments, when we prioritize learning over worldly involvement. Sometimes, we have hadas moments, when we prioritize action over enlightenment. And sometimes, we have aravah moments, when we have no energy for learning nor doing. All of these are necessary for living, and during the month of Tishrei, we can appreciate each of these moments. As we sit in our Sukkah, we are wrapped in the wings of the Shechinah, and experiencing its divine protection as we celebrate the Festival of Ingathering.
Shemini Atzeret begins our prayers for rain, and here’s where I get a little extra mystical. Rain is connected to femininity through its association with the womb of creation, fertility, and gentle power which renews life. In Genesis, G-d creates the world from a formless void, using language which conveys ideas of a cosmic womb, a life-generating space which G-d filled with his purpose to design our world. As humanity was created in G-d’s image, the womb metaphor is solidified. As rain comes, it revives the earth, making it fertile, restoring the feminine principles of creativity, emotional depth, and spiritual renewal in the very land we walk on. Rain comes most often as a gentle power, one which arrives calmly, sustaining all life.
Simchat Torah is the time when we celebrate finishing the annual cycle of reading the entire Torah and beginning again. Here, we are brought back to Rosh Hashanah and its new beginnings, with an added layer of holiness and celebration. On this day, it is tradition to dance and revel in the joy of our peoplehood, our identity, our Jewishness, and, let’s add, our femininity. G-d has given us a remarkable gift by making us women. While we revel in the holiness of Torah, let us also revel in the holiness of womanhood.

The tragedy of Clara Haber
By DAVID TOPPER This story of the sad and short life of a remarkable woman, Clara Haber, should be better known. I hope this essay is a step in that direction. Her legacy deserves it.
She was born Clara Helene Immerwahr on June 21, 1870 to two Jewish parents. Interestingly, the German surname breaks down into: immer (always, forever, still) and wahr (true, real, right). Take your pick. I like: Still real.
Being smart and hardworking, she was the first woman to obtain a doctorate in Chemistry from the University of Breslau, part of Germany at the time (today it’s in Poland). This was in 1900. Several years before that, she had converted to Christianity. A year later, 1901, she married Fritz Haber, who also had a doctorate in Chemistry. (He was from Breslau too; they met at a dance.) He was two years older than her, and he also had converted to Christianity, in the early 1890s.
This act of conversion – starting in the early 19th century, when, on the heels of the French Revolution, Jews came out of their ghettos – was more common among European Jews than you might think. There were about 2000 conversions per year throughout the century. Some famous ones are: the poet Heine, the mathematician Kronecker, and the composers Mendelssohn and Mahler. In most cases it was the only road to prestigious appointments, otherwise restricted to Christians.
On June 1, 1902 Clara gave birth to what would be their only child, Hermann. The job of raising Hermann was given to her, Fritz being too busy with his important work in his Chemistry Lab – thus ignoring her work in Chemistry. He put in 18-hour workdays, barely leaving time for dinner (if he ate at home) and some sleep. Plus, Hermann was a sickly child, and hence Clara spent all her time raising him – without Fritz. In letters she spoke of her unhappiness in the marriage: especially “Fritz’s oppressive way of putting himself first in our home and marriage, so that a less ruthlessly self-assertive personality was simply destroyed.” These are harsh and powerful words, expressing her extreme disillusionment and frustration with her married life. Yet it was true; her potentially successful career in Chemistry was dead. She never accomplished anything after her degree. The family and household took all her time and energy.
What, therefore, was this important work that kept Fritz busy and out of the home? He was the Director of the Institute for Chemistry in Berlin. His first major discovery was synthesizing ammonia from nitrogen gas and hydrogen gas, which revolutionized the production of fertilizer. The result was higher yields in agriculture throughout Europe and eventually the world. (Even today, it’s been estimated that food produced from this process supports almost half of the world’s population.) For this Haber was seen as a hero, alleviating otherwise mass starvation. In 1918 he got the Nobel Prize in Chemistry for this work.
But there was a flipside to all this: the fertilizer could also be used to make explosives. This too Fritz explored, especially with the start of the First World War in August 1914. Out of this work came poison gases, and thus the creation of chemical warfare.
Fritz was a staunch German patriot and nationalist, supporting the War from the beginning. For example, he signed the “Manifesto of the Ninety-Three,” with other German intellectuals in support of the War. (Incidentally, Albert Einstein, who was living in Berlin at this time – they were good friends – refused to sign the document.)
Fritz not only worked in the lab producing the chemical, he was also involved in supervising their deployment on the war front. Thus, he was in Ypres (near Flanders), Belgium on April 22, 1915. As one historian has drolly put it: “The small Belgium city of Ypres is to chemistry what Hiroshima is to physics.” Indeed, this was the first use of chemical weapons in military history. They released around 170 tons of poison gas across a 4-mile front. There were an estimated 800- 1400 immediate deaths among the French and Algerian troops. Fritz left before the battle was over. During the entire so-called Second Battle of Ypres, from April 22 to May 25 – there were over 67,000 casualties among the French, Canadian, and British troops.
(As an aside: this battle was commemorated by John McCrae, who wrote “In Flanders Fields,” a poem recited every Remembrance Day here in Canada.)
Leaving Belgium, and after a brief stay at home, Haber immediately went to the Eastern Front to oversee gas released against the Russian Army. For all this work, he was given the rank of Captain by the Kaiser.
Meanwhile, Clara, usually alone, was raising Hermann, and taking care of the household, not having time to explore all the chemistry she would like to do. In letters she says that her husband’s work with poison gases is a “perversion of the ideals of science” and “a sign of barbarity, corrupting the very discipline which ought to bring new insights into life.” She also witnessed the accidental death of a former classmate, who was in Fritz’s lab working with these chemicals. To make matters worse, she was hearing rumours of Fritz’s involvement with other women. (Humm, it seems he found time for that!)
When Fritz returned home from Belgium (I don’t know the exact date), and before he left for Russia on May 3rd, there was a celebration at their home on the success of the gas attack. There are reports of arguments between Fritz and Clara, but we don’t know the details. What we do know, as a fact, is this. On the following morning, May 2, 1915, Clara took Fritz’s military pistol and walked into their garden. She shot into the air (presumably to test the gun) and then, pointing it into her chest – she pulled the trigger. Hermann heard the shots, ran into the garden – and his mother died in his arms. The following morning, Fritz left for Russia, to supervise the gas attack on the Eastern Front.
At this point in my story, Clara is gone. But there’s more to tell, and – if she knew the rest – I’m sure she would want the reader to know it too. Especially this.
During the final weeks of the First World War, on the Western Front, the Allies now launched a series of gas attacks in the district of Ypres on the Germans. On the night of October 13-14, 1918, just south of Ypres, in the town of Wervik (or Werwick), the British forces used mustard gas on the 16th Bavarian Reserve Infantry Regiment. One German corporal serving as a messenger in the army was caught in the attack, and was partially blinded. He was able to stagger to safety and eventually was taken to a military hospital in Germany to recover. We know about this because he wrote about it in his 1925 book, Mein Kampf. Adolph Hitler recalled: “I stumbled and tottered back with burning eyes…. [M]y eyes were turned into glowing coals; it had grown dark around me.” He was still in hospital at the end of the War on November 11, 1918, at the signing of the Armistice with Germany’s surrender. While lying blinded, he says he had a vision to enter politics to “save” Germany. How much this is true and how much perhaps psychosomatic, due to the shock of the mustard gas – or just plain hyperbole – we will never know. But it led to his myth of Germany’s “stab in the back” – and all that followed with the rise of the Nazi Party.
In 1933, when the Party took over the country, Fritz was still alive. During the 1920s he had a staff at the Kaiser Wilhelm Institute developing more gases, such as the cyanide gas formulation, Zyklon A, which was used as an insecticide to spray on plants. In the spring of 1933, with the passing of Hitler’s law of removing all Jews in professional jobs throughout the country, Fritz was stunned. But it was worse. Fritz not only lost his job: but all his awarded metals, his many accolades, the staunch patriotism and nationalism, his service to the country, even the conversion to Christianity – it all came to naught, since he was a Jew by birth. Thus: his legacy was completely erased from all records, in all German history – as if he never had even existed.
And so, in August, he left the country. He first went to Paris, then to Spain, England, and finally Switzerland. He even took a brief trip to Palestine, where he bequeathed his private Library to the nascent Weizmann Institute, and was offered a position there. He accepted it, but never fulfilled it. He died of severe coronary sclerosis in Basel, on January 29, 1934 at the age of 65.
A major outcome of the Nazification of Germany, as we know, was World War Two. And with that – the Holocaust. Both Clara and Fritz died before all that; but not members of their families.
Most of Clara’s families were assimilated Jewish professionals and intellectuals, which was no buffer to the Nazi plague. Most of the Immerwahrs died in Auschwitz or Theresienstadt. Only a few had fled to France and then the USA. None was in Germany in post-1945.
As for Fritz’s family, he had a younger half-sister, Frieda. She fled to Jerusalem and survived the war. But her children and grandchildren all died in Auschwitz.
Also, after Clara died, Fritz later married Charlotte Nathan. They had two children: Eva and Ludwig. Just before he died, Fritz sent them to Switzerland; from there all three went to England, surviving the Holocaust.
Then there is Hermann, the only child of Clara and Fritz. After the Nazi party took over Germany, Hermann immigrated to the USA. There he married and had a child, Claire, who became a chemist. Not surprisingly, he had episodes of depression over his adult life, eventually committing suicide in 1946. Sometime later, Claire did the same.
As a final point in this part of my story, I note the following fact. The pesticide gas, Zyklon A from Faber’s lab contained an odorant – to warn users. When the Nazis took over Faber’s lab in the Institute, they removed the odorant, producing Zyklon B, the gas used in the mass murders in the gas chambers during the Holocaust.
As a coda to this story, I wish to compare Clara’s story with Mileva Marić, Einstein’s first wife. The reason for this will be seen below.
In brief, here’s Mileva’s story. Born in 1875 to a Christian Orthodox Serbian family, she had a dislocated hip that resulted in her walking with a limp all her life. Although this isolated her as a child growing up, she had a very loving and doting father who encouraged his very bright daughter in her school work (she was especially good at math) and was proficient at the piano. Moreover, she was the first girl to attend high school physics courses in the entire Austro-Hungarian Empire.
After graduation, she applied to the prestigious Zurich Polytechnic, since (as we saw) Switzerland admitted women to all classes. She passed the entrance exam and majored in Mathematics. With all this potential, it seemed that the future was hers to make, even as a woman. Then, in a small Physics course, she met Einstein. They quickly became a couple. Except for the time they spent together, Mileva still did her school work and passed all her courses over the first three years.
In her fourth year she started on a thesis, hoping to get a PhD. But she failed her final exams. She repeated them, but still didn’t pass. What happened? I find it hard to believe that this sudden change in her performance was due to the tests being too tough for her – after all that she achieved up to this time. The thing that was different – and which I believe was the source of her predicament – is this: she was pregnant with a child fathered by Albert. With the baby in her belly, she just couldn’t concentrate on the tests.
She went home to her parents and the child was born (a girl, they named Lieserl). Being illegitimate, Lieserl was left with her parents (who were very supportive) and Mileva went back to live with Albert. They married in January 1903, in a small civil ceremony. Neither set of parents was there. And so, Mileva became a housewife – and eventually the mother of two boys. Like Clara, all the earlier promises came to naught. Mileva didn’t even get a university degree – let alone her aspiration of a PhD.
By around 1909 Albert was being noticed by the physics community for his publications on relativity (a subject he essentially created) and quantum physics. Mileva wrote to her closest friend that Albert “lives only for his work” and that the family “is unimportant to him.” This strain on the marriage came to a peak in the spring of 1914 when they moved to Berlin, where he had accepted a prestigious position in the Physics section of Kaiser Wilhelm Institute.
For this we need to come back to Fritz and his friendship with Einstein. In many ways their friendship was unexpected, since (except for being born Jewish) they had little in common – opposite on the topics of nationalism, patriotism, war (Albert was a pacifist). Even in dress: Fritz was meticulous in his three-piece suits, and Albert sloppy in dress with his hair all over the place. Yet, when they first met in September 1911 at a scientific society meeting in Karlsruhe, they quickly became close friends. In particular, Fritz was so impressed that he became the chief orchestrator to draw Einstein to the position in physics at the Berlin Institute.
Thus, late in 1913, Einstein was offered a position, and he accepted it. But Mileva was reluctant to leave Switzerland. One main reason: Albert had a divorced cousin in Berlin, Elsa, who Mileva knew Albert was visiting when attending meetings in the city. She even suspected (correctly) that it was an intimate relationship.
Nonetheless, around Christmas 1913, Mileva traveled to Berlin to look for a place to live. She stayed with Fritz and Clara, and – not surprisingly, from all we know about them – the two women quickly and deeply bonded. They certainly had lots to talk about: given their similar situations regarding their stifled careers and abusive husbands. Mileva found an apartment, and in April 1914 she, Albert, and their two boys moved to Berlin.
They were not there for even a month, and the marriage entered a new phase. Albert demanded a series of rules for their relationship. Mileva was to do the laundry, prepare him three meals a day, and keep his office clean – all without any personal relations, no intimacy, and never being seen in public together. It was degrading and cruel; she was reduced to being a maid and a cook.
Mileva tried to accept all this, but quickly found that she couldn’t endure the humiliation. Fritz and Clara knew about all this. Clara consoled Mileva. Fritz acted as a mediator, as the marriage completely broke down. Fritz was a witness, signing the separation agreement. In July 1914 Mileva packed up her things, and she and the two boys went back to Switzerland, where she lived for the rest of her life. The following month was the start of the War – and, ultimately, in May 1915, Clara’s suicide.
There it is: Clara’s sad story, and how it overlapped with Mileva Einstein’s story – with ultimately their short, but profound, friendship.
I hope all this helps bring to light the legacy of this potentially brilliant, surely fascinating, and ultimately tragic woman.
Clara Helene Immerwahr Haber is long gone. Yet, for me, she is: Still real.
