Correspondence, annotated daily calendars, and photographs, relating to the German socialist and communist movements, and to the imprisonment of Rosa Luxemburg during World War I. Includes a memoir by Mathilde Jacob, personal secretary to Rosa Luxemburg, entitled "Von Rosa Luxemburg und ihren Freunden" (present in variant typescript forms with annotations, and on microfilm), and correspondence of Mathilde Jacob.

Mathilde Jacob, the admirer, friend, confidant, and secretary of Rosa Luxemburg from December 1913 to January 1915, was born in 1873. Between 1913 and 1942 Mathilde Jacob made her living as a public stenographer, typist, and translator. Her years prior to World War I and through the 1920s were devoted to the successive causes of the Social Democratic Party and Communist Party in Germany. She was introduced to these movements by her brother Joseph Jacob, who also helped her obtain such clients as Franz Mehring, Karl Radek, Paul Levy, and Rosa Luxemburg. Mathilde Jacob first met Rosa Luxemburg in December 1913 during her employment as the typist for the publication Sozialdemokratische Korrespondenz. A friendship developed which led to Mathilde's role as Rosa's primary source of external information and material needs during her years of imprisonment from 1914-1918 for opposition to German participation in World War I. Following Rosa Luxemburg's death in 1919, Mathilde Jacob worked for Paul Levy until his death in 1930. In 1942 she was deported to a concentration camp where it is believed that she perished.
