Karl Heinrich Ulrichs
In the 1860s, Ulrichs moved around Germany. He was always writing and publishing. He was always in trouble with the law for his words. In 1864, his books were taken and banned by police in Saxony. Later the same thing happened in Berlin. His books were banned in Prussia. Some of these papers were found in the Prussian state archives. They were published in 2004. Many of Ulrichs' most important books have been published.
