Korczak's Pedagogical Tree: Roots and the First Branches Grow at the Children's Hospital on Śliska Street.

The Bersohn and Bauman Children's Hospital before the Reconstruction: The True View from Śliska Street. This rare, colourized historical photograph provides a crucial correction to standard biographical accounts, which have traditionally misidentified this perspective as a view from Sienna Street. In reality, this depicts the hospital grounds from the Śliska Street side, captured in its original architectural form prior to the major rebuilding and expansion of the hospital complex. Most significantly, this image captures the exact structural environment of Janusz Korczak's daily life during his formative medical tenure. The small, two-story building standing on the far left, right at the edge of the street, is the original gatekeeper’s lodge where Korczak lived together with his mother, Cecylia Goldszmit, following his formal appointment as a resident city physician (lekarz miejscowy) in 1905. While the hospital gatekeeper occupied the ground floor, Dr. Henryk Goldszmit and his mother shared the flat on the first floor. It was within these very walls, in the direct shadow of the clinical wards, that he balanced his demanding medical duties with the writing of his early, foundational pedagogical texts.

September 9 (21), 1899. An article "Szpitalik dla dzieci" (Little Hospital for Children), published in the weekly Czytelnia dla Wszystkich (No. 38). Henryk Goldszmit was then a mere freshman medical student, a nineteen-year-old boy looking at his future domain. He signed this text using the hidden cryptonym H. R.

The Architectural Blueprint of the Bersohn and Bauman Hospital: Mapping Korczak’s True Topography. This original hand-drawn architectural plan provides the ultimate, unyielding cartographic proof that settles the debate regarding the hospital's orientation and the exact location of Janusz Korczak’s home. The orientation of the map is clearly marked in Cyrillic script at the top and bottom:Top: Сѣнная (Sienna Street) bordering the lush hospital garden and orchard rows.
Bottom: Сlizkaya / Слизкая (Śliska Street), establishing the actual front-facing boundary of the original complex.
The Anatomy of the Gatekeeper's Lodge (The Home of Korczak and His Mother)
Following the boundary line along the bottom edge (Śliska Street) to the far left, the plan clearly depicts the footprint of the gatekeeper's lodge—the very site of Dr. Henryk Goldszmit's domestic and medical life from 1905 to 1912. As clearly delineated on the map, this building is a distinct, pink-colored structure shaped like a block-letter "C" (or an inverted "U" open towards the inner courtyard). This specific architectural configuration allowed the building to serve its dual purpose perfectly: its long outer edge faced and monitored Śliska Street directly, while the inner recess formed a small, private transit enclave right at the hospital's main entrance gate.
When Korczak was appointed as the resident city physician (lekarz miejscowy) in 1905, he and his mother, Cecylia Goldszmit, moved onto the first floor of this very "C"-shaped structure, directly above the ground-floor quarters of the hospital gatekeeper. This map beautifully anchors your previous discovery, providing a precise spatial context to the rooms where Korczak balanced his intense clinical duties with the quiet writing of his early pedagogical manifestos.


Korczak's Pedagogical Tree: Roots and the First Branches Grow at the Children's Hospital on Śliska Street.

A Topographical and Archival Inversion 
by Roman Romuald Wasserman Wroblewski
The monumental legacy of Janusz Korczak—his fully developed methodology of child sovereignty, the children’s parliament, and the radical empathy of his final years—did not emerge from a vacuum. It is a massive pedagogical tree. If we trace its crown, heavy branches, and trunk backward through time, we find ourselves in a specific physical topography in Warsaw: the Bersohn and Bauman Children's Hospital between Śliska and Sienna streets.

The First Branches: From Śliska Street to the Orphanage
The clinical and human experience gained on Śliska Street generated the very first functional "branches" of Korczak’s life’s work. It was his daily contact with the neglected children of the Warsaw slums and interaction with Dr Izaak Eliasberg that pushed him directly toward the Summer Camps Society (Towarzystwo Kolonii Letnich) and his formative, experiential trips to Michałówka, where his early sociological books were conceived.
Furthermore, it was at Śliska Street that Korczak formed a deep, lifelong scientific alliance and friendship with Dr. Izaak Eliasberg, a prominent physician at the hospital. It was through this organic collaboration that the Orphan Asylum at 2 Franciszkańska Street. This institution served as the structural and ideological stepping stone, the direct evolutionary precursor, toward Korczak's ultimate monument: the Orphanage at Krochmalna 92. Every single branch of his legacy grew from this soil.

The Roots: The Resident Physician and the Hidden Flat Above the Gatekeeper
Moving deeper down the tree, we hit the heavy roots of his actual medical tenure. In 1905, as a newly graduated physician, Henryk Goldszmit assumed the permanent post of resident physician (lekarz miejscowy) at the hospital on Śliska Street, a position he would hold for eight grueling years until 1912.
Standard biographers often omit the raw, domestic reality of this period. By structural regulations and vocational call, the resident doctor had to live permanently on the hospital grounds. Korczak did not occupy a room in the main medical pavilion; instead, he moved into the modest, one-story building standing directly on Śliska Street—the first house on the left in historical photographs. The hospital gatekeeper lived on the ground floor, while young Dr. Henryk Goldszmit lived on the first floor together with his mother, Cecylia Goldszmit.
Following the family’s total financial ruin and the tragic mental decline of his father, these small rooms over the gatekeeper's quarters became a sanctuary for Henryk and his mother. Here, in the intense proximity of his domestic duty to his mother, and surrounded by the relentless cries of sick infants from the courtyard, the "Korczak habitus" was forged. In these rooms, he penned his first major publicistic and pedagogical manifestos.

The First Seed (1899): "Szpitalik dla dzieci"
But what was the absolute first seed (The Seed) from which this entire tree germinated? To find it, we must go back even further, to the very bottom of the archive—to September 9 (21), 1899.
Below is the first complete English translation of the article "Szpitalik dla dzieci" (Little Hospital for Children), published in the weekly Czytelnia dla Wszystkich (No. 38). Henryk Goldszmit was then a mere freshman medical student, a nineteen-year-old boy looking at his future domain. He signed this text using the hidden cryptonym H. R.
This text is the foundational spark—the material evidence that his universalist worldview was already fully formed before the turn of the century:
LITTLE HOSPITAL FOR CHILDREN.
Speaking of shelters for healthy children, which are undoubtedly very necessary in a large city, we shall also say a few words about another institution that renders significant services to the poor population of our city—without distinction of religion.
We have just visited the little hospital for children on Śliska Street, and we must admit that the idea of creating such establishments for these impoverished, helpless, tiny creatures is surely among the most beautiful and humanitarian. Let us step inside the building; bypassing all the comforts of the entire little hospital—the cleanliness, the spaciousness of the wards, and other favorable conditions which are naturally capable of attracting a class usually detached from doctors and medicines—let us observe the entire internal arrangement.
There are seven wards in total, properly lit, with sufficient and viable ventilation, designated for sick children, containing 42 beds. In addition to this, however, the little hospital possesses several other rooms, namely: an operating room for surgical cases, an analysis room, and several outpatient clinics for visiting patients. In these outpatient clinics, free medical advice is provided not only to children but also to sick adults without distinction of religion, both women and men, whereby the poorest also receive medicines free of charge.
In the little hospital on Śliska Street, protective smallpox vaccinations are also administered; the hospital’s income varies: first and foremost, the founders of the institution remember its existence, contributing a fixed annual fee; next, from the interest on capitals; from voluntary donations by various individuals, and finally, from accidental revenues.
The chief physician of the little hospital is Dr. J. Portner; besides him, the little hospital has several attending physicians and a resident physician.
This is what we saw in this useful institution, which naturally must leave a good impression on everyone. A sick little wretch, brought here from a dark, foul-smelling basement, or rather from a dreary den stubbornly called a dwelling—will by that very fact feel unutterable relief under the influence of the clean atmosphere and comfortable bedding. Furthermore, if we take into account the medicine administered on time, the skillful handling of the patient, and the accurate medical advice delivered in due season, we shall have an idea of how vital the significance of a children's hospital can be in a district densely populated by the poor. There, a mother is not only unable to watch over her child, but often lacks the time for such a luxury, even though from the bottom of her soul she would long to bring relief to her sick little one.
Moreover, can this working-class mother, thinking of tomorrow, overworked and often forced to maintain the entire family, occupy herself with a sick child? Can she call a doctor to the house, and can she truly afford the medicine? No! And so, this institution is a blessing for her, relieving her of so many troubles.
The little hospital on Śliska Street combines within its building an extraordinarily rich and valuable medical library, which, continuously expanded with serious works from the field of medicine, currently contains about 1,400 volumes, in addition to specialized medical journals, both domestic and foreign. Young medical candidates, students, and others who do not even belong to the hospital staff also frequently benefit from the valuable works of the library.
H. R.

The Material Truth
When the nineteen-year-old student Goldszmit twice hammered the phrase "without distinction of religion" into his very first hospital review, the seed of his entire life was planted. He established that a child's suffering has no nationality and no creed.
When he returned there in 1905, he simply grew into the very roots he had observed. The tree that eventually blossomed at 92 Krochmalna Street and stood unbowed in Treblinka was entirely structured by the architecture of this small, one-story house over the gatekeeper's lodge on Śliska Street. The timestamps of history do not lie.

Szpitalik na Śliskiej: Początek i dom Janusza Korczaka (1899–1912).

Trudno o bardziej przejmujący i precyzyjny splot dokumentów archiwalnych. Z jednej strony winieta tygodnika „Czytelnia dla Wszystkich” (Nr 38) z 9 (21) września 1899 roku. W spisie treści tego numeru widnieją obok siebie dwa teksty młodego Henryka Goldszmita: „Szpitalik dla dzieci”, podpisany kryptonimem H. R., oraz „Zurych”, podpisany jako Janusz. „Szpitalik” to prawdopodobnie najwcześniejszy literacki zapis Korczaka, w którym jako student medycyny opisuje Szpital Dziecięcy im. Bersohnów i Baumanów między ulicami Śliską i Sienną w Warszawie.
Z drugiej strony – archiwalna fotografia ukazująca ten sam szpital w okresie międzywojennym. Gdy w 1905 roku Korczak uzyskał tam stałą posadę jako lekarz miejscowy (miejscowy lekarz), związał się z tą placówką na kolejne osiem lat. Zgodnie z regulaminem i powołaniem, zamieszkał na stałe na terenie szpitala, by być dostępnym dla chorych dzieci o każdej porze dnia i nocy.
Korczak nie mieszkał w głównym gmachu pawilonu chorych, jego domem na terenie szpitala był widoczny na zdjęciu po lewej stronie pierwszy, jednopiętrowy budynek stojący przy samej ulicy Śliskiej.

Mało kto zna jednak dokładną topografię tego miejsca. Korczak nie mieszkał w głównym gmachu pawilonu chorych z charakterystyczną rotundą. Jego domem na terenie szpitala był widoczny na zdjęciu po lewej stronie pierwszy, jednopiętrowy budynek stojący przy samej ulicy Śliskiej. Na parterze tego domu mieszkał szpitalny stróż, natomiast młody doktor Henryk Goldszmit zajmował (razem z matką) skromne mieszkanie na pierwszym piętrze. To właśnie tam, nad stróżówką, powstawały jego najważniejsze wczesne manifesty pedagogiczne i publicystyczne, zanim w 1912 roku przeniósł się do nowowybudowanego budynku Domu Sierot na Krochmalnej 92.

"Controlled Blindness": The October 10th, 1946 Residence Permits and the Secret Swedish Alliance with Aliyah Bet

Above is an application form for a Swedish residence permit that Holocaust survivors with Polish and Hungarian national passports had to submit. This document serves as a prime material example of "controlled blindness" exercised by the Swedish state to facilitate illegal immigration to Mandatory Palestine. The responsibility for this rapid application process, as well as the references for the future S/S Ulua passengers, likely resided entirely within the Jewish Refugee Welfare Society in Stockholm. Significantly, all of these applications request a permit lasting only a few weeks—until December 31, 1946. Most were signed on October 10th, 1946.

While the form strictly requires an authentic signature on page two, several of the signatures had been copied from previous documents, placed onto separate slips of paper, and literally glued onto the forms—presumably by the staff of the Jewish Refugee Welfare Society in Stockholm.

While the form strictly requires an authentic signature on page two, several of the signatures had been copied from previous documents, placed onto separate slips of paper, and literally glued onto the forms—presumably by the staff of the Jewish Refugee Welfare Society in Stockholm. This unorthodox method was clearly tolerated by the Swedish authorities, serving as a strong indication of the government's positive and cooperative attitude toward the upcoming Ulua mission. Notably, a minor bureaucratic oversight can be seen on one of the stamps used, where the word "Jewish" was misspelled as "Jewis."

Why was the permitted length of stay so short? The Jewish Refugee Welfare Society planned for the S/S Ulua (or an alternative vessel) to depart well before the end of the year. However, the Swedish authorities had an additional, tactical reason for enforcing such a tight deadline. They were fully aware that the passengers' official destination—"Cuba"—was a complete fabrication, and they knew the British authorities were actively trying to intercept and block the voyage. Therefore, the entire operation had to be executed with extreme speed and in total media silence.

When the S/S Ulua finally docked in Trelleborg and the Holocaust survivors boarded, the British diplomatic pressure was rendered useless. The Swedish government could legally argue that there was no way to stop their departure: the passengers were foreign citizens carrying valid national passports, they were not Swedish subjects, and their legal permits to remain in Sweden had expired.

My research showed that most of the "Ulua passengers" were survivors who arrived in Sweden during the UNRRA mission White Boats.


Commentary on the Left Document: The Administrative Alibi for the October Contingent
The document on the left provides undeniable, material proof that the Jewish Refugee Welfare Society and the Swedish authorities originally planned for the maritime departure to take place during the month of October 1946. The Swedish text explicitly locks in a specific "contingent of 600 Jews" slated for emigration to Cuba.
The mentioned passport stamp, translated as “Prevented from departing before 31/10 1946” served a dual, highly tactical purpose. Administratively, it was an explicit notice to local municipalities that these individuals were strictly transit passengers and were barred from claiming state-subsidized Swedish rationing cards (ransoneringskort). Politically, it acted as a ticking legal clock. By codifying that their departure was expected by the end of October, the Swedish state ensured that these survivors remained legally detached from the domestic system, preparing the ground to seamlessly push them out of Swedish jurisdiction the moment the S/S Ulua arrived. Notably, this document features the exact typo you exposed: "Jewis Refugees Welfare Society."
Commentary on the Right Document: The Anatomy of a Collective "Fake" Visa
The document on the right is a verified copy of a copy (Avskrift av Avskrift) of the landing collective visa issued by the Cuban Consulate General in Antwerp, Belgium, dated August 5, 1946. It is a classic specimen of the operational camouflage utilized by Aliah Bet. The visa explicitly specifies that the individuals “according to the list here attached are permitted to immigrate to the Republic of Cuba... for the purpose of agricultural work.”
The Cuban visa was an absolute fiction. There were no individual, personalized visas issued; instead, it was a sweeping, faceless collective permit meant to bundle an entire contingent of hundreds of people under a single administrative umbrella. The restriction that the immigrants were explicitly barred from “any others works /commerce &&./” was a standard diplomatic clause used by South American consulates to appease domestic labor unions, but here it served as an ironic backdrop. Neither the organizers, the Swedish state, nor the passengers had any intention of establishing a Jewish agricultural colony in Cuba. The document's sole historical function was to provide a plausible transatlantic destination on paper, satisfying international maritime laws just long enough for the S/S Ulua to clear the Trelleborg harbor and steer directly toward the shores of Mandatory Palestine.


English Translation of the Left Document (Swedish to English)


The applicant, who belongs to the contingent of 600 Jews, who through the care of the Jewis Refugees Welfare Society have been granted the opportunity to emigrate to Cuba during the month of October 1946, has received the following stamp in his/her passport:
'Prevented from departing before 31/10 1946. Does not entitle to the issuance of rationing cards.'

The Genesis of Korczak's Method: From "How to Love a Child" (1919) to the Stenographic Record of the Child's Soul.



To truly understand how Janusz Korczak revolutionized the "recording of children’s voices", one must trace the technical apparatus he utilized. The institutional implementation of stenography during the conferences of Mały Przegląd was not a late, spontaneous editorial experiment. Its methodological foundation was laid a decade earlier.

Korczak formally mentions stenography for the very first time in his seminal work How to Love a Child: The Child in the Family (Jak kochać dziecko: Dziecko w rodzinie), published in 1919. In this book, Korczak draws a direct parallel between the meticulous diagnostics of psychiatry and the future of pedagogy:
"In psychiatric clinics, the stenographer records the monologues and conversations of patients; it will be the same in the future in pedagogical clinics. Today we have only material: a catalog of children's questions."
For Korczak, stenography was the ultimate anti-censorship tool—a way to outrun the swiftness of children's speech and preserve it without the intrusive filtering, stylization, or moralizing of an adult hand. This deep methodological commitment is precisely why Korczak later hired Igor Newerly to be his private secretary and the editor-in-chief of Mały Przegląd. Newerly’s primary, indispensable asset for the job was his fluent mastery of stenography, allowing him to act as the objective, rapid human recording device for the children’s parliament.

In Victoria Van Orden Martinez’s new book, several 'Female STEM Pioneers' are described.

In Victoria Van Orden Martinez’s new book, several 'Female STEM Pioneers' are described. I knew one of them personally: Professor Halina Neujahr, or grandmother 'New Year' as my children called her. Halina was one of the few survivors who knew everything about the Holocaust, not just her own personal experiences like most others. 

When looking through Halina's photo album, I found a page with two photographs from the Rosöga camp outside Strängnäs. Halina Neujahr, a Holocaust survivor, stayed at the camp from October 24, 1945, to June 26, 1946. Here are two winter pictures. Halina is on the far right. In the left image, Halina wrote: 'In the shadow of the chimney.' This was despite the fact that no real shadow was cast by it. What Halina meant was her true association with the chimneys of the crematoria in the death camps, including Majdanek, where her mother Gitla was murdered. Her comment on the picture to the right is also distinct. She notes that 'auntie' has arrived and that the chimney no longer frightens her. By 'auntie,' she meant that her menstruation had returned. Halina arrived in Sweden with UNRRA's White Boats.

Inny artykuł Jawana z fotografią w „Małym Przeglądzie” z 1 kwietnia 1927 roku.


Na samej górze to pierwsze i ostatnie fotografie opublikowane w Małym Przeglądzie 24 i 31 grudnia 1926 roku. Jakość, mimo rozmiaru fotografii, jest bardzo słaba. Prawdopodobnie fotografie zrobił podpisany reporter, Jawan. Pod pseudonimem Jawan w „Małym Przeglądzie” pisał Jerachmiel Wajngarten (znany również jako Jerachmiel Weingarten). Był on od początku powstania jednym z najważniejszych starszych współpracowników i redaktorów Małego Przeglądu, pisma założonego przez Janusza Korczaka w 1926 roku. W „Małym Przeglądzie” pisał artykuły, felietony oraz przeprowadzał wywiady (m.in. z młodymi artystami teatralnymi). W 1929 roku założył i redagował własne ilustrowane pismo dla młodzieży wzorowane na idei korczakowskiej – „Gazetę Młodych”. Prowadził też inne dodatki literackie dla dzieci oraz pisał recenzje teatralne (również pod pseudonimem Jawan). Urodził się w Warszawie w grudniu 1902 roku w rodzinie kupieckiej i był wszechstronnie wykształconym publicystą, pedagogiem oraz tłumaczem piszącym w języku polskim i hebrajskim.

Korczak wielokrotnie odpowiadał na pytania dzieci, dlaczego jest tak mało fotografii. Pisał, że to bardzo dużo kosztuje.

מאָשקע/modyf. משה מאַך זיך נישט וויס n – Mojsze, Pretend You Know Nothing
INTERPELATION.
In Yiddish: Mejsze mach zych nyszt wysen.
In Polish: Gadaj zdrów (Talk all you want / It's like talking to a brick wall).
Is it known to the councilors of the capital city of Warsaw that for a month now Mały Przegląd has been demanding the removal of barbed wire from the Krasiński Garden?
Mały Przegląd asks with absolute firmness whether the councilors will raise this matter at the session, because public opinion is deeply shaken and outraged—and things might turn sour?
We wait impatiently for an answer, and we enclose greetings to the whole family and bows.
Archival Commentary: The Fight for a Sliver of Green and the Satirical Bite
This short text from the fourth issue, dated November 5, 1926, exposes a real topographical tragedy of pre-war Warsaw. The Krasiński Garden, along with the Saxon Garden, was among the absolute favorite places of Janusz Korczak and the children from the adjacent Jewish quarter. In this severely overcrowded, northern part of the city, there was a desperate lack of green spaces. The children literally had nowhere to breathe, and the fact that the city administration cordoned off their tiny slivers of freedom with barbed wire sparked genuine outrage.
The phonetically written phrase "Mejsze mach zych nyszt wysen" (in classical Yiddish: Mojsze, makh zikh nisht visn) translates literally to: “Mojsze, pretend you know nothing about it”—the Yiddish equivalent of playing dumb. The editorial team deliberately pairs this idiom with the Polish phrase "Gadaj zdrów" ("it's like talking to a brick wall"). Korczak and the children act as formal petitioners lodging an "interpellation" to the Warsaw City Council to protect the playground, while simultaneously mocking the soullessness of adult bureaucracy: We are submitting an official petition, but the city councilors will just "pretend they know nothing," leaving us to futilely "talk to a brick wall." 
Debunking the Myth: Did Korczak Know Yiddish?
A swarm of false myths has surrounded Korczak’s alleged "ignorance" of the Yiddish language. Many superficial biographers swear that the Doctor did not know it at all, attempting to forcefully cram him exclusively into the framework of Polish culture. This also stems from an old class prejudice of the assimilated intelligentsia, who dismissed Yiddish as a "slum jargon." The truth, as I have documented on my blog, is quite different: Korczak understood Yiddish perfectly by ear. While he did not speak it in elite salons or write his books in it, he learned it methodologically directly from working-class children (as recorded by Paulina Appenszlak at the orphanage on Franciszkańska 2). He had to know it, and he did, in order to listen to the children's grievances during summer camps in Michałówka or at Krochmalna Street. The very subtitle of this Interpellation serves as direct, hard proof of his comprehension. [1, 2, 3, 4, 5]
P.S. The Living Speech of Pan Misza and Khane Kostek
My father, Pan Misza, who worked for many years as an educator alongside Janusz Korczak in the Orphanage, carried the vibrant, juicy folklore of the Warsaw Jewish street through the horrors of the war. Whenever he heard a complete absurdity or wanted to dismiss something as utter "nonsense!", he would use another, exceptionally rare Yiddish idiom: "A zajur af Hane Kostek!" (A yor oyf Khane Kostek! – אַ יאָ r אויף חנה קאָסטעק).
In Jewish Warsaw, "Khane Kostek" was a synonym for a quarrelsome, lower-class woman—the ultimate archetype of perpetual bad luck and constant complaining. The phrase functioned as an ironic curse: “May such a [bad] year fall upon Khane Kostek, but not upon us,” or “What you are saying makes as much sense as wishing a good year to Khane Kostek.” It is tangible proof that the circle of educators around Korczak breathed the authentic, unpolished speech of Muranów and Wola, rather than just the dry theories found in textbooks.
