POST 193: GERTRUDE STEINTHAL, TALENTED BELLE ÉPOQUE ERA PAINTER & DAUGHTER OF MY GREAT-GREAT-AUNT JENNY BRUCK


Note: An art historian from Utrecht University working on her master’s degree in art history alerted me to the existence of another accomplished artist in my family tree, Gertrude “Traute” Steinthal. Born in Berlin in 1868, she began her artistic career there before moving to Paris in 1899 during the Belle Époque era. She died in 1906 when she appeared to be on the verge of attaining recognition. She seems to have specialized in painting portraits of German-Jewish social elites, though any surviving works are likely to be in private collections and difficult to locate.

POST 189: CEREMONY FOR THE RESTITUTION OF THREE PAINTINGS LOOTED FROM MY FATHER’S COUSIN FÉDOR LOWENSTEIN DURING THE SECOND WORLD WAR: SEPTEMBER 16, 2025

 

Possessing no musical, judicial, medical, stomatological, nor artistic skills which abound in my family tree, I’m always fascinated when I find yet another closely related ancestor endowed with such deftness. I learn about such individuals sometimes through my own research, other times through the contribution of readers. The subject of the current post is Gertrude “Traute” Thomine, née Steinthal, whose mother was Jenny Bruck, one of my great-great-aunts. I learned about Traute from Brianah “Bri” Lee, an art historian working on her master’s degree in art history at Utrecht University in the Netherlands. I’d never previously heard of Traute Steinthal. 

As Bri initially explained, she was the daughter of Jenny Bruck (1835-1902) and Gustav Steinthal (1825-1895). Jenny was the younger sister of my great-grandfather Fedor Bruck (1834-1892). (Figure 1) Jenny (Figure 2) and Fedor were among my great-great-grandfather’s Samuel Bruck’s eldest children. Samuel (1808-1863) (Figure 3), to remind readers, was the original owner of my family’s hotel/restaurant in Ratibor (today: Racibórz, Poland), the Bruck’s “Prinz von Preußen” Hotel. For frame of reference, Traute was my first cousin two times removed, though this is of scant import.

Bri Lee first came across Traute Steinthal while doing preliminary research on the Union des Femmes Peintres et Sculpteurs, Union of Women Painters and Sculptors, and learned she’d exhibited with them from 1903-1906. Taken by her intriguingly titled works, she decided to further investigate and quickly realized that, while very talented, not only had she never heard of Traute but no one else had either. As Bri put it to me, “I quickly realized that she was a successful painter and sits at a pivotal intersection of Belle Époque history. Then I found a photograph of her (Figure 4), and a sketch, and I knew I had to complete this research.” (personal communication) Bri also found low resolution photographs/illustrations of two of Traute’s paintings (Figures 5-6) and an enhanced copy of her signature. (Figure 7)

Like most people who contact me these days, Bri found me through my blog. She reached out while I was in Europe preparing to fly to Paris dealing with another accomplished family artist, my father’s first cousin Fedor Löwenstein. As I reported in Post 189, I traveled to Paris to retrieve three paintings confiscated from him by the Nazis at the Port of Bordeaux in December 1940 and shipped to the Jeu de Paume in Paris. The three paintings, among 25 seized by the Nazis, survived the Nazi rampage to destroy so-called degenerate art. 

Having already collected a lot of information about Traute before finding me, Bri hoped I could fill in her biography and help locate any surviving images of the artist and her artworks. She is particularly eager to locate a portrait of Jenny Bruck painted by her daughter in 1892 and find any documents that might be preserved within the family. Having previously been unaware of Traute, I was unable to assist in this regard. 

While Traute was born in Berlin in 1868, she relocated to Paris around May 1899, according to Bri, likely with her mother Jenny. In October 1899, she got married in Paris to Alexander Edmond Thomine in Paris, familiarly called “Edmond,” an engineer and the Director of the French affiliate of the Babcock & Wilcox company. Knowing I would be meeting with representatives of the French Ministry of Culture and Paris’ Musee d’art et d’histoire Judaïsme (mahJ) and aware of Traute’s connection to Paris, I asked several art historians I know if they’d ever heard of her. 

David Zivie (Figure 8), my contact at France’s Ministry of Culture and the chef de la Mission de recherche et de restitution des biens culturels spoliés entre 1933 et 1945, Head of the Mission for Research and Restitution of Cultural Property Looted between 1933 and 1945, graciously undertook a search through the archival databases he has access to. David found and sent me Traute and Edmond’s 1899 marriage certificate (Figure 9); a marriage announcement from Le Figaro dated the 17th September 1899 (Figure 10); Traute’s February 27, 1906, death certificate (Figure 11); a death announcement from Le Figaro dated the 28th February 1906 (Figure 12); and another death announcement in La Vérité dated the 2nd of March 1906. (Figure 13) David also sent me information on the sale of three of Traute’s oil paintings from artprice.com (Figure 14), a database of art market information with a coverage of more than 700,000 artists of fine art with over 30 million auction results. While this was new to me, Bri had already found all this information.

Quoting from one of Bri’s emails, below is some of what she’s learned about Traute Steinthal:

“There are a handful of contemporaneous profiles written about Edmond available on Gallica and RetroNews, two of which speak to Traute. It seems she was well respected socially in her time, and from what I can garner, connected to Jewish and German communities even after her move to France. Strikingly, she is recorded in public registry books as a painter even after her marriage- something that speaks to her professionalism and dedication, as well as, perhaps, her relationship to her husband. In fact, from the little I can gather, it does seem as though they were a good pair, with Edmond supporting her artistic practice, attending society events with her, and likely, connecting her to French artists who would eventually nominate her to the Société des Artistes Français. Sadly, she would exhibit her most works, and be accepted to this society, only a month before her death. Her obituary notes she was 38, however, if her birth date of 1 May 1868 is correct, then she would have been only 37 years old. I managed to identify a few days ago that she is buried in the Montparnasse Cemetery. To my understanding, Traute never had children.

As of right now, I have a fairly clear timeline of public events from 1892 to her death in 1906, simply by tracking the digitized newspapers and periodicals that speak to her. However, her time studying is still very vague, as is, of course, her personal experience of it all. I am hoping as I continue my research to be able to piece together her early life, her time studying art, her experience as a German Jew, then as both German and a Jew in France (the Franco-Prussian War had done much to make relations between both nationalities difficult, then to add on rising antisemitism, as well as the hardship for her simply as a woman painter of the time…). I am also attempting to find as many images as possible of her works and hopefully locate a handful that remain in private collections- though this is undoubtedly the hardest part of this research journey. Given she painted portraits of many German-Jewish social elites, I fear that many works from before her move to France are likely lost.”

In closing, I would add that given the unexpected success I’ve achieved over the years uncovering information about the subjects of my blog posts and finding descendants of some, I hold out hope that a reader may stumble on this post and add to what is known about Traute Steinthal. This would indeed validate Bri Lee’s valiant efforts.

POST 173: HISTORIC REMAINS OF A FAMILY “CASTLE” IN SOUTHWESTERN POLAND

 

Note: In this post, I discuss a so-called “castle” presently located in southwestern Poland that was once owned by the noble von Koschembahr family. My great-granduncle Wilhelm Bruck married into this family and adopted his wife’s matronymic. The manor house which survives in dilapidated condition was once the home of his father-in-law’s two widowed sisters.

POST 172: HISTORIC TOPOGRAPHIC MAPS OF THE GERMAN REALM, INCLUDING TODAY’S POLISH TERRITORIES

In Post 115, I introduced readers to Wilhelm Bruck (1849-1907) (Figure 1), one of my great granduncles, who married Margarete von Koschembahr (1860-1948) (Figure 2) on the 14th of September 1884 in Berlin, Germany. Wilhelm was the younger brother of my great-grandfather Fedor Bruck (1834-1892) (Figure 3), the second-generation owner of the family business in Ratibor [today: Racibórz, Poland], the Bruck’s “Prinz von Preußen” Hotel.

Upon their marriage, Wilhelm added his wife’s matronymic to his name. The unusual adoption of a wife’s surname most typically happened when the wife was a so-called peer, that’s to say, was a hereditary titled noble in her own right. The result was that Wilhelm and his descendants became known as “Bruck-von Koschembahr,” though the Bruck surname was dropped entirely upon the family’s arrival in America.

By all measures the von Koschembahr descendants are my distant relatives though until the year before last I’d never been in contact with any members of this branch. While my uncle Dr. Fedor Bruck was particularly impressed with links to nobiliary members on our ancestral line, took special pains to note them in his hand drawn ancestral trees, and may even have been in touch with members of this branch, this has never been of explicit interest to me. Regardless, in December 2023, I was contacted by an American descendant of this offshoot of my family, Christopher von Koschembahr. Christopher mentioned his mother had stumbled upon my blog. He also explained he was the son of Dieter von Koschembahr (1929-1995), who I knew to be one of the grandsons of Wilhelm Bruck and Margarete von Koschembahr.

As an aside, during our exchanges, Christopher asked when my father changed his surname from “Bruck” to “Brook.” I didn’t know at the time. However, in connection with my ongoing German citizenship application, I’ve since learned my father became Gary Otto Brook upon becoming an American citizen in July 1955. I think Christopher’s question stemmed from the fact that he serendipitously named his daughter “Brookes,” so had the original surname been retained, she would have been known as “Brookes Bruck.”

In March 2024, Christopher mentioned to me his intention to visit one of the former family estates currently located southwestern Poland, a short distance northeast of the German border town of Görlitz. Embedded in this email was a message from my third cousin, Kurt Polborn, to Christopher with some of the historical background on the property and the name of the Polish town where the estate is located, Żarki Średnie. Like Kurt and me, Christopher and Kurt are third cousins. A brief digression before I discuss what I know of the von Koschembahr family property and its former residents.

As I explained in the previous post, Post 172, upon learning that Christopher’s family once owned a “castle” in what is today called Żarki Średnie, Poland (Figure 4), I turned to a comprehensive 1893 map of Silesia once sent to me by Paul Newerla. I had discovered the town was called “Kesselbach” during the Prussian era, though was unable to find it on the detailed Silesian map. This is when I turned to the 1:25,000 scale “Urmesstischblätter” military maps discussed in my prior article. (Figure 5) After learning Żarki Średnie/Kesselbach was located 7.5km or 4.66 miles northeast of Gorlitz, I located it on map number “4756-Penzig/Pieńsk.” (Figures 6a-c)

I was unable to find Kesselbach in the meyersgaz.org database even by using “star as a wildcard” in the “Search” bar. This points out the advantage of having several different map sources one can turn to. It was only after I found an old postcard on eBay referring to the castle as “Schloß-Mittel Sohra” (Figure 7) that I found “Mittel Sohra,” in meyersgaz.org. (Figure 8)

Based on the picture in Wikipedia of the von Koschembahr “manor house,” as they refer to it, the mansion appeared to be maintained and in very good shape. (Figure 9) Other pictures found online seemed to corroborate this. (Figure 10) This was a grand illusion as Christopher discovered when he visited the former family estate in July 2024. (Figure 11) While the structure is still standing, the floors and roof are collapsing, the windows and doors are missing or broken, and roots are growing through the foundations and openings. (Figures 12a-b) When Christopher used hand gestures to communicate with Polish laborers working nearby on the day he visited, they gesticulated that tossing a hand grenade into the building would solve the problem.

As a retired archaeologist I have come across multiple such historic structures over the years while conducting pedestrian surveys on the public lands in the western United States. This is one reason the deteriorating mansion holds a peculiar fascination for me, different than it may for the average reader. Adding this to the history that my cousin Kurt Polborn told me about the place, I’ve been able to relate it to specific individuals who lived there. This is not always possible even with recent historic era ruins.

Let me relate the part of the story I’ve been told and connect it to historic documents I’ve uncovered.

I told readers at the outset of this post that my great granduncle Wilhelm Bruck married Margarete von Koschembahr and added her matronymic to his surname. Margarete’s father was Leopold von Koschembahr (1829-1874) (Figure 13) married to Amalie Mockrauer (1834-1918). (Figure 14) As a quick aside, my Bruck ancestors are related by marriage to Mockrauers over several generations, but that’s a story for another day.

 

Figure 13. Leopold von Koschembahr (1829-1874) in around 1860

 

Figure 14. Amalie Mockrauer (1834-1918) in around 1904

 

Leopold von Koschembahr was Kurt Polborn’s great-great-grandfather. According to Kurt, Leopold filed for bankruptcy on a few occasions, and his large family would likely not have survived without the help of his mother and his Jewish in-laws. Amalie Mockrauer wrote in her diary about the financial disasters of her married life.

As a reflection of the self-perceived “superiority” of the nobility vis a vis the bourgeoisie, upon Wilhelm Bruck’s death in 1907, his widow Margarete dropped the Bruck surname and reverted to her maiden name.

Returning to the ruined manor house in Żarki Średnie, according to Kurt, Leopold von Koschembahr’s had two sisters. The older one was Julie Leopoldine Anna von Koschembahr (1827-1883), referred to as “Anna”; the younger was Isidore Mathilde Helene von Koschembahr (1833-1887), familiarly called “Isidore.” Though they were six years apart, both got married the same year in 1859. Anna married Adolph von Blankensee (1812-1871) (Figures 15a-b), while Isidore wed Major Otto von Heugel (1826-1871). (Figures 16a-b)

Their respective husbands fought in the Franco-Prussian War, also known as the Franco-German War of 1870-1871. Both died during this conflict in France within weeks of one another. Adolph von Blankensee died from Typhus on the 11th of January 1871, while his brother-in-law Otto von Heugel died on the 29th of January 1871 in a place called La-Queue-en-Brie (Figures 17a-b), a commune in the southeastern suburbs of Paris. Following their husbands’ deaths, the widows apparently lived together in the family manor in Kesselbach until their deaths. Both are recorded as having died in Görlitz, the largest nearby town.

Figure 17b. Major Otto von Heugel’s name listed as a casualty in the Franco-Prussian War, 1870-1871

 

The only known depiction of Anna von Koschembahr is an endearing painting from ca. 1830 standing alongside her younger brother Leopold. (Figure 18) The original of this painting is owned by the descendants of Kurt’s recently deceased uncle, Clemens von Koschembahr, Chistopher von Koschembahr’s uncle. In Post 75, I wrote about this Biedermeier-style painting because my third cousin, Agnes Stieda, née Vogel, owns a replica of this painting. (Figure 19) How a copy of this painting came to be made is unknown.

Figure 19. Copy of the same painting as in Figure 18 owned by my third cousin, Agnes Stieda

 

No images are known of Isidore. However, given the extensive von Koschembahr family, it is probable that a likeness of her survives among the family’s ephemera. It is my hope that one of her von Koschembahr descendants may stumble upon my blog and scrutinize their family photos.

The history of the von Koschembahr manor house is unknown. Discovery of the so-called “grundbuch,” the German land register that records property ownership and other details that would have been maintained by a special division of the local court, would provide details on the castle’s construction and ownership. Whether the grundbuch survived the devastation of WWII is also unknown.

I can only surmise what happened to the manor house following Isidore’s death in 1887. Neither Anna or Isidore had any children, However, a younger von Koschembahr sibling, Erich Wilhelm Adolf von Koschembahr (1836-1890), had two daughters, and one may have inherited the property. I would posit the estate continued to be owned by Anna and Isidore’s descendants since titled families tended to own multiple estates around the country. Regardless of what happened to the property following the death of the two widows, there can be no doubt the family lost ownership of the estate at the end of WWII when the family fled the area as the Russians were approaching.

Pictures of the manor house, including the one on Wikipedia, show the shell of the castle still in restorable condition. These pictures, probably taken in the last 10-15 years, suggest that someone lived in and maintained the property until shortly before then. I strongly suspect I’ll eventually write a postscript to this post as I learn more about the history of the von Koschembahr manor house.

The dilapidated remains of the von Koschembahr castle in Żarki Średnie holds a particular appeal to me as a retired archaeologist. Because most historic era remains found throughout the United States are not related to titled families or known individuals and are assuredly not connected to my family, learning of a surviving structure that is piques my interest. I’ll leave it at that.
