Carl Eisenburg was born in Bad Kissingen on March 12, 1899 as the first of four children of the cattle dealer Oscar Eisenburg and his wife Rosa, née Kissinger. On both his mother’s and his father’s side he came from long-established Jewish families in the Franconian spa town.

From September 1909, Carl Eisenburg attended the Royal Realschule Bad Kissingen and graduated in July 1915 with “rather good success”. In the last three years of his time at school he was a member of “Bayerischer Wehrkraftverein”, some sort of a Bavarian branch of the German Boy Scouts with a definitely military focus. His certificate of conduct from May 31, 1916 especially emphasizes his commitment for “Wehrkraftverein”: “Eisenburg … has proved himself in any respect. Endowed with a serious sense of duty and visible enthusiasm for the matter at hand he has been a valuable support for the leaders of the group. Because of his overall demeanour he could be trusted with the leading of a group. He has been educated according to the rules of a military education of young people” (Jack-Steinberger-Gymnasium Bad Kissingen, Schularchiv: Schülerakte Karl Eisenburg – School archives, student’s file).

On March 22, 1926, Carl Eisenburg left his hometown and moved to Glogau, the place of birth of his wife Lotte Kronheim (*1910). In the Nazi Era, he emigrated to Argentina together with his parents and his wife. Carl’s father died in Buenos Aires on October 20, 1940 at the age of 66. Carl Eisenburg continued the family tradition in Argentina: He was a very successful cattle breeder. After her husband’s death, his mother Rosa obviously moved to her daughter in Montevideo where she died on September 8, 1949. Carl Eisenburg died nine years after his wife on September 23, 1979 in Buenos Aires where he was also buried. The couple didn’t have any children.
