Salomon Blumenfeld’s Children Thekla and Felix: Killed by the Nazis

In April, 1933,  Salomon Blumenfeld’s two children from his first marriage, Thekla Blumenfeld Gruenbaum and Felix Blumenfeld, were both living in Kassel, Germany. All of their children and grandchildren were also still in Germany. With Hitler’s rise to power, some of the family members left Germany not long afterwards. But others were not so fortunate.

Thekla Blumenfeld Gruenbaum was murdered by the Nazis. She was first deported to Theriesenstadt on July 25, 1942.  Two months later on September 26, 1942, she was sent to the extermination camp at Treblinka where she was killed. She was seventy years old. She had lived a hard life—losing her mother when she was just a toddler, being left behind by her father a few years later, losing her husband, and then being killed at Treblinka.

Thekla’s daughter Caecilie and her husband Walter Herzog were living in Krefeld, Germany, before the war. I am still researching where and when, but the evidence indicates that the two children of Caecilie and Walter, Renata and Manfred, were sent to England before the war.1 Walter was a successful silk tie manufacturer and had deposited a fair amount of money in a Swiss banking account; that account was confiscated by the Nazis.2 In December 1941, both Walter and Caecile3 were deported to the concentration camp in Riga, Latvia. Walter was later transferred to Buchenwald where he was “declared dead” on May 8, 1945.

Caecile was sent from Riga to the Stutthof concentration camp.4 The Holocaust Encyclopedia provided this information about the Stutthof camp:5

Conditions in the camp were brutal. Many prisoners died in typhus epidemics that swept the camp in the winter of 1942 and again in 1944. Those whom the SS guards judged too weak or sick to work were gassed in the camp’s small gas chamber. Gassing with Zyklon B View This Term in the Glossary gas began in June 1944. Camp doctors also killed sick or injured prisoners in the infirmary with lethal injections. More than 60,000 people died in the camp.

The Germans used Stutthof prisoners as forced laborers. … In 1944, as forced labor by concentration camp prisoners became increasingly important in armaments production, a Focke-Wulff airplane factory was constructed at Stutthof. Eventually, the Stutthof camp system became a vast network of forced-labor camps….

The evacuation of prisoners from the Stutthof camp system in northern Poland began in January 1945. When the final evacuation began, there were nearly 50,000 prisoners, the overwhelming majority of them Jews, in the Stutthof camp system. About 5,000 prisoners from Stutthof subcamps were marched to the Baltic Sea coast, forced into the water, and machine gunned. The rest of the prisoners were marched in the direction of Lauenburg in eastern Germany. They were cut off by advancing Soviet forces. The Germans forced the surviving prisoners back to Stutthof. Marching in severe winter conditions and treated brutally by SS guards, thousands died during the march.

In late April 1945, the remaining prisoners were removed from Stutthof by sea, since Stutthof was completely encircled by Soviet forces. Again, hundreds of prisoners were forced into the sea and shot. … It has been estimated that over 25,000 prisoners, one in two, died during the evacuation from Stutthof and its subcamps. 

Soviet forces liberated Stutthof on May 9, 1945, and liberated about 100 prisoners who had managed to hide during the final evacuation of the camp.

How did Caecilie manage to survive this ordeal? Was she one of the hundred who were hiding in the camp during its final evacuation? Her odds for survival were overwhelmingly low, yet somehow she did. After time as a displaced person and with the help of HIAS (Hebrew Immigrant Aid Society), she was able to immigrate to the US in July 1946.

I was able to locate more information about Thekla’s brother Felix Blumenfeld through several sources, including a detailed and well-sourced biography online. Felix had studied medicine at both the University of Marburg and the University of Munich. He served as a ship’s doctor and later as doctor in a POW camp during World War I. As we saw, Felix lost his first wife Thekla Wertheim in 1917, and on February 16, 1920, in Nordhausen, Germany, he married his second wife Helene Petri, who was not Jewish. She was born on October 20, 1894, in Nordhausen, the daughter of Fritz Petri and Bertha Peter. Felix and Helene were living in Kassel, where Felix was a practicing pediatrician.

The detailed biography of Felix I found online describes in great detail all the contributions that Felix made as a doctor and citizen in Kassel.

Encouraged by the high infant mortality rate among children of poor parents, he began to use his position as a doctor and to get involved in society. At his suggestion, milk kitchens were built in which perfectly hygienic milk-grain mixtures were produced as baby food and sold using a deposit bottle system . The products were also given free of charge to the poor.

He also served as the medical director of the children and infant’s home/hospital in the city and also was involved in other charitable and civic organizations.

Despite his service in World War I and all these contributions he made as a doctor and citizen, Felix was persecuted by the Nazis. 

Just a few weeks after the National Socialists came to power on April 1, 1933, as a Jew, he was deprived of the management of the children’s hospital, he was banned from working and had to give up his apartment and practice…. His property and library were confiscated and owing to the fact that his wife Leni was not Jewish, he was initially allowed to live in his summer house a…. He was forced to do auxiliary and road construction work and had to collect rags and scrap at the municipal scrap yard . He was exposed to constant discrimination and surveillance by the Gestapo.

A second biography written for the occasion of the installation of Stolpersteine in Felix Blumenfeld’s honor in Kassel also reported this information and explained that Felix ultimately decided to end his own life in order to avoid deportation and also to protect his wife Helene.

Before killing himself on January 25, 1942, Felix wrote a long letter to his two sons in America, Edgar and Gerd, explaining why he had decided to take his own life. The first part of the letter details some of the abuse and persecution he had endured, and then he ends with these paragraphs, as translated by DeepL:

But enough of that ! Let’s get to the main thing ! Life is no longer bearable for me! All my hope, to which I had clung, was to get out of this hell and to be united with you in a near or distant time. I dare not count on that hope any longer. For with the years of war my years of life also increase. But the worst thing at the present moment is that out of sheer arbitrariness they have deprived me of all my property and referred me to my hands work or to public welfare. Subsequently, they also “expropriated the wife of the Jew”, although since 1939 there had been a legal separation of property, i.e. there was no legal basis for this. Leni was in Berlin and has the prospect of getting part of her property back if she gets a divorce. I want to agree to this divorce in order not to endanger Lenimutter’s livelihood again and again through my person. In that case, however, my life, which has been ruined through no fault of my own, has lost all the more meaning, especially since it is not known what else will be done to us.

Under these circumstances, death seems more desirable to me than an existence with ever new torments. I am therefore leaving this world of meanness, baseness and inhumanity in order to enter eternal peace and to seek the path that leads from darkness to light.

My last thoughts belong to my faithful comrade, on an often thorny path, and to you my beloved children, my Edgar, Gerd, Annchen, Lotte and Little Gerard ! You will be with me in the hour that demands strength and courage. Especially with you, my Gerd, I would have liked to hold a conversation, you dear, you good one! Stay as good as you have been so far, and be the one who makes sure that you always stay together faithfully. Then I am always in your midst and remain eternally connected with you. Without looking backwards, move forward and build a more beautiful life in a hopefully better world. May it be a comforting thought to you that your father is relieved of all fear, worry and pain after his departure. We remain united ! ! You will never forget me, I know that, because my love for you was, is and will be infinite.

Like his sister Thekla, Felix Blumenfeld lost his mother as a baby, then his father, and then his first wife. Nevertheless, he grew up to be a devoted father and pediatrician who contributed greatly to his community. Although not technically murdered by the Nazis, Felix is also rightfully counted among those whose deaths were caused by Nazi persecution.

There was one more death in the family attributable to Nazi Germany. Thekla Blumenfeld Gruenbaum’s grandson, Caecilie and Walter Herzog’s son Manfred, was killed in action while fighting for the Allies in Europe sometime in the spring of 1945.

Thus, the Nazis killed both Thekla and Felix, the two children Salomon Blumenfeld had with his first wife Caecilie Erlanger, as well as Thekla’s son-in-law Walter Herzog; in addition, Thekla’s grandson Manfred Herzog died fighting the Nazis in World War II. I can’t help but think about how Felix and Thekla’s lives would have been different if their father Salomon had taken them with him when he moved to Spain.

They were survived by the rest of the family. Their stories will be told in the next post.
