For many years students of German Labor history have speculated about the possible existence of a Tony Sender Nachlass somewhere in the United States. Ms. Sender, a Social Democratic journalist, was active in the Socialist Women's anti-war movement during World War I, played an important local role in the German Revolution of 1918 (in Frankfurt/Main), was a leading member of the Independent Social Democratic and later the Social Democratic party, held an important position in the German Metal Workers Union, and sat in the Reichstag throughout the Weimar Republic. She'fled Germany in 1933 and eventually migrated to the United States where she died in 1964 at the age of 76. Following her death what remained of her papers were entrusted to the State Historical Society of Wisconsin in Madison where they are now located and available for use.

The dictionary is intended as a reference volume for students and scholars whose interests lie in the area of Modern British Radicalism. We have attempted to include the major and minor figures active in the labor movement, parliamentary reform, Chartism, socialism, republicanism, feminism, positivism, disestablishment, temperance, education, and imperial reform.
