By 1939, all three of the children of Moses Blumenfeld IIA had died, leaving behind their children, the seven grandchildren of Moses Blumenfeld IIA. Their fates were determined by the Nazis. This post will examine the fates of the children of Moses’ daughter Antonie Blumenfeld Katz and her sister Hedwig Blumenfeld Kaufmann as well as that of Antonie’s husband Moritz Katz.
Antonie’s husband Moritz Katz stayed in Marburg after Antonie died in 1939 until he was deported to Theriesenstadt on September 7, 1942; he was killed there on September 11, 1944, at the age of 73. He and Antonie were survived by their two children, Artur Katz and Margarete Martha Katz Jacobsohn. Those two children survived by leaving Nazi Germany and immigrating to Palestine (now Israel) in the 1930s.

Artur was a lawyer in Berlin until the Nazis deprived of him his right to practice law after 1933. According to his nephew Yoram Jacobson, Artur soon left for Palestine, where he changed his name to Avraham (which was probably always his Hebrew name). According to a profile on MyHeritage, Avraham was married to Edith (Hannah) Walter, and they had three children. I have no other sources so far to verify that information. Avraham Katz died on October 22, 1978, in Haifa, Israel.

Antonie’s daughter Margarete Martha Katz had married Friedrich (Fritz) Max Jacobsohn sometime before they immigrated to Israel in 1939. Fritz was born in Hanover, Germany, on July 13, 1899; his father’s name was Abraham. I have no information about his mother. Fritz, an insurance agent, had been taken to Buchenwald Concentration Camp after Kristallnacht in November 1938 and was determined to leave Germany once he was released. With the help of his brother-in-law Avraham Katz, he and Margarete immigrated to Palestine/Israel on July 24, 1939. They became citizens of Palestine on October 20, 1941.1

Margarete and Fritz had one child, their son Yoram, who was born on November 27, 1944, in Haifa. Yoram Jacobson became a prominent Kabbalist and Hasidic scholar. He taught at several academic institutions in Israel, including Hebrew University and Tel Aviv University, and overseas, including at Harvard. He was also the author of many books and articles. Yoram was married twice and had four children.
Fritz Jacobson died August 24, 1963, in Haifa. He was 64. He was survived by his wife Margarete Katz Jacobson, who died forty years later on April 12, 2003, at the age of 96. They were survived by their son Yoram and his children. Yoram died April 16, 2017, in Israel. He was 72.
Although Moritz Katz died at the hands of the Nazis in Theriesenstadt, the two children he had with Antonie Blumenfeld survived by immigrating to Palestine. Today they have living descendants in Israel.
The story of Antonie’s sister Hedwig Blumenfeld Kaufmann does not end as well.
Hedwig’s daughter Anna Kaufmann and her husband Julius Leyser did not go to Palestine with their cousins. They did, however, leave Germany for Amsterdam, but sadly that was not enough to escape the Nazis. Anna, her husband Julius, and their two young sons Ernst and Hans were all deported from the Westerbork detention camp in Amsterdam to the extermination camp at Sobibor on July 23, 1943, and were murdered there. Anna was 42, Julius was 45, Ernst thirteen, and Hans eleven. An entire family wiped out, including two young boys.

Hedwig’s son Albert Kaufmann survived the Holocaust by immigrating to Brazil. His marriage to his first wife Dorothy had ended before she died on March 31, 1938, in Berlin, Germany.2 Albert had traveled to Brazil in 1924 before he’d married Dorothy, so perhaps he knew it was a good place to immigrate.3 He died in Rio de Janeiro, Brazil on June 10, 1986, at the age of 84. According to his death record, he was survived by his second wife Georgina Correa. She was born in Brazil in 1921, the daughter of José Correa de Mendonça and Anna Emilia da Conceicao.4 The death record indicates that Albert left no children. He died from cancer.

UPDATE: I received an email today (1/5/22) from the daughter of Paul Blumenfeld. I learned from her that Albert Kaufmann did have a daughter named Inge and that Inge had two sons. So Albert Kaufmann, and thus his mother Hedwig Blumenfeld Kaufmann, do have living descendants!
The story of the family of their brother Ernst will be told in the next post.
