FAMILY LEDERMANN DETAILS.
Franz Anton Israel Ledermann was the son of Benjamin (Benno) Ledermann and Lucie Schachtel.
Benjamin Ledermann was born on March 4th 1847 in Ostrowo. He married Lucie Schachtel on November 11th 1878 in Breslau. Lucie was born June 26th 1860 in Eisenstädt.
Benjamin was a lawyer. The couple became three children:
Curt Otto 1879 in Beuthen, died in 1918.
Käthe Hedwig 1881 in Köningshütte.
Franz Anton Israel 1889 in Hirschberg.
Benjamin died June 18th 1911 and Lucie on September 12th 1936 in Hirschberg.
Both Käthe and Franz moved to Holland with their families.
Käthe Hedwig (Jadwiga) Ledermann was born on 25 March 1881 in Königshütte (now Chorzów) in Upper Silesia as the daughter of Dr. Benjamin (Benno) Ledermann and his wife Lucie, née Schachtel. Her father was a lawyer in Hirschberg (Giant Mountains), but there is no further information about her mother. Little is known about Käthe's youth, but she learned to play the piano and practiced it with great joy until the end. In a letter in 1937, she described that she played symphonies by Haydn and Beethoven four-handed with a friend.
On February 1, 1902, she married the lawyer Dr. Felix Kaempfer from Posen (Poznan) in Hirschberg. Her marriage certificate states that she had no profession. In the telephone directory of 1939 she was noted as a "representative", the reason for this is not known.
They had three children:
Heinz Martin (*1904)
Otto Hans (*1906)
Eva Pauline (*1918)
Otto Hans died in 1918, only nine months after his little sister, who was only one day old. In the same year, Käthe's brother Curt also died.
In 1920, the family moved to Berlin, where Felix Kaempfer had also studied. They probably had to leave their now Polish hometown because of their "German attitude" (according to Franz Ledermann). The family moved into an apartment at Potsdamer Straße 109, which they kept even after the death of Felix in December 1920. In 1924, her brother Franz married, and Käthe became his maid of honor. She kept in close contact with her brother's family and was a frequent guest at the Ledermanns' house concerts.
Käthe Kaempfer moved to Kufsteiner Straße 18 in Schöneberg in 1931. In 1936, her son Heinz married Eva Wrzeszinski, there she was also one of the maids of honor. In the same year, her son and his wife went to the Netherlands, Heinz was initially an authorized signatory of a German company in Rotterdam, then from 1939 at a Dutch trading company.
A letter she wrote to Heinz and Eva in the Netherlands in 1937 shows that Käthe Kaempfer was culturally interested and active in many ways. She wrote about her symphony society, about making music together, visiting museums and giving lectures.
She emigrated together with the grandmother of her daughter-in-law, Jenny Kaiser, to the Netherlands in 1939. There she first lived with Heinz and Eva and from September 1940 at Koningsweg 5 in Beekbergen until she was sent to Scheveningen prison on 29 October 1943. It is said that she sang there for her fellow prisoners.
On November 16, 1943, she was deported to the Auschwitz extermination camp via the Westerbork transit camp, where she was murdered just three days later.

Anne Frank stays for a few weeks in Beekbergen in July 1941. She is staying at the house “Op den Driest” on Koningsweg 5, together with her friend Sanne Ledermann and Sanne’s parents. Sanne’s sister Barbara and another friend, Tineke Gatsonides, are also on holiday there.
The house Op den Driest is inhabited by the Kaempfer family, who are relatives of the Ledermanns.
From her holiday address in Beekbergen, Anne sends a letter to her grandmother. She describes Op den Driest as an old-fashioned but cozy house. Anne does get rather bored there. Because of the bad weather, she and Sanne spend a lot of time indoors. They mostly play with Raymond, the Kaempfers’ little son. Anne also reads many books and sleeps better in Beekbergen than in noisy Amsterdam.
Anne also sends a letter to her father, Otto, inviting him to come to Beekbergen:
“… then you take the 9:30 train from Amsterdam, then from the station you take the bus to Beekbergen from Apeldoorn. Then you ask to get off at the ‘Zonnehuis’, then you ask for Koningsweg 5, ‘Op den Driest.’”
Despite these precise directions, the visit never took place. Later that year, in September, father and daughter did spend a few days together in Arnhem.
Meanwhile, life for Jews in occupied Netherlands was becoming increasingly difficult. On 6 July 1942, Anne and her family went into hiding in the Secret Annex, a space on the first and second floors behind Otto Frank’s business on Prinsengracht in Amsterdam.
