Sara Blumberg, née Eisenburg, was born in Bad Kissingen in January 1864 as the daughter of the Bad Kissingen “Ökonom” (economist) and cattle dealer Hess Eisenburg and his wife Sisle Sette (Sedla), née Stern. There are different dates of birth to be found in the sources, January 9, and in some sources also January 12, 1864 are mentioned. 

Sara Eisenburg married Isidor Blumberg who lived in Heidelberg. He came from Trebur near Groß-Gerau in South Hesse and was a cattle dealer and master butcher. Since 1893 he ran his own butcher’s shop in Heidelberg. Sara may already have lived in Heidelberg then because their son Kurt (Karl) was born there in August 1894. Kurt was killed few weeks before the end of World War I at the age of 24. The Blumenbergs ran a flourishing butcher’s shop in Hauptstrasse in the old town of Heidelberg and lived there till 1930/31. After Isidor had obviously retired and leased his business, the Blumbergs left the old town and moved to Handschuhsheim in 1931 where they lived as tenants. The butcher’s shop in an exposed location in the old town, which had been taken on by the Jewish butcher Gottfried Marx as a tenant was on the NSDAP (National Socialist German Workers Party)’s list of businesses to be boycotted in 1933. Until they were deported in 1940, Mr. and Mrs. Blumberg lived in Handschuhsheim.

On October 22, 1940, they were part of the deportation of Jews of Baden to the internment camp Gurs in the South of France, where they died after only few weeks at the ages of 76 and 75 years respectively. Sara Blumberg died in Gurs on December 13, 1940, her husband Isidor outlived her for one week and died on December 20, 1940.
