Peter Langmann and ...

Liberalism in the late 19th century German Empire

The Berliner Tageblatt was founded in 1871 by the 27-year-old Rudolf Mosse. Although the newspaper struggled at first, Mosse's previous experience as the business manager for other Berlin newspapers helped him attract a large group of advertisers. By 1880, with the help of the respected editor and journalist Arthur Levysohn, Mosse built the Berliner Tageblatt into the most popular newspaper of its kind in Germany. Despite its liberal sympathies in political matters, the Berliner Tageblatt was so widely read that many Junkers were jokingly accused of secretly slipping the Tageblatt inside their copies of the Kreuzzeitung. This kind of success made the Jewish Mosse a very unpopular figure for opponents of liberalism--and for proponents of anti-Semitism.
Meanwhile, a rival to Rudolf Mosse, Leopold Ullstein, created his own publishing empire around the liberal Berliner Zeitung, The liberal journalist Peter Langmann originally founded this newspaper in the mid-1870s. However, Langmann soon ran into financial difficulties, and Ullstein stepped in to assume control of the newspaper in 1878. The partnership of Ullstein and Langmann quickly turned the small newspaper into one of the most successful institutions in Berlin--with almost 25,000 readers by the end of 1879. Although the Berliner Zeitung represented a political viewpoint similar to the Berliner Tageblatt, it was often more outspoken in its criticism of the government. The newspaper's constant attacks against the Anti-Socialist Laws brought repeated prosecution by government authorities, but also won the loyalty of many Berlin workers.
