Siblings

Kafka's parents had six children; Kafka was the eldest. His two brothers, Georg and Heinrich, died in infancy; his three sisters, Gabriele ("Elli") (September 22, 1889 – fall of 1942), Valerie ("Valli") (1890–1942) and Ottilie ("Ottla") (1892–1943), are believed to have been murdered in the Holocaust of the Second World War. Ottilie was Kafka's favourite sister.

Gabriele was Kafka's eldest sister. She was known as Elli or Ellie; her married name is variously rendered as Hermann or Hermannová. She attended a German girls' school in Prague's Řeznická Street and later a private girls' secondary school. She married Karl Hermann (1883–1939), a salesman, in 1910. The couple had a son, Felix (1911–1940), and two daughters, Gertrude (Gerti) Kaufmann (1912–1972), and Hanna Seidner (1920–1941). After her marriage to Hermann, she became closer to her brother, whose letters showed an active interest in the upbringing and education of her children. He accompanied her on a 1915 trip to Hungary to visit Hermann, who was stationed there, and spent a summer with her and her children in Müritz the year before he died.

With the outbreak of the Great Depression in 1929, the Hermann family business experienced financial difficulties and eventually went bankrupt. Karl Hermann died February 27, 1939, and Elli was supported financially by her sisters. On October 21, 1941, she was deported together with her daughter Hanna to the Łódź Ghetto, where she lived temporarily with her sister Valli and Valli's husband in the spring of 1942. She was probably killed in the Kulmhof extermination camp in the fall of 1942. Of Elli's three children, only her daughter Gerti survived the Second World War. A memorial plaque commemorates the three sisters at the family grave in the New Jewish Cemetery in Prague.
