Karl Peter Heinzen (22 February 1809 – 12 November 1880) was a revolutionary author who resided mainly in Germany and the United States.
After eight years, he became an executive functionary for the Rhenish railroad in Cologne and later part of the administration of a fire-insurance association in Aachen.
The banning of these newspapers from Prussia prompted him to write Die preußische Bureaukratie (The Prussian Bureaucracy) which was confiscated immediately on its appearance and led to a criminal investigation.
Heinzen fled to Belgium to escape prosecution and in March 1845 began a series of socialist writings with Steckbrief, an indictment of the higher courts of the Prussian Rhine Province.
[2] Marx argued that Heinzen was mistaken in conceiving of morality as ahistorical rather than as a contingent phenomenon emerging from social and economic relationships.
In March 1854, he, Bernhard Domschke, and others deliberated on a statement of principles of the radical Germans which became known in German-American circles as the "Louisville Platform."
He furthered the cause by using the nom de plume Lousie Mayen in addressing Arnold Ruge and his position on women's suffrage.
Forty-Eighters like Reinhold Solger, Christian Esselen and Friedrich Hecker thought suffrage for women would set back culture a century.
[4] Heinzen was also an isolated voice in the German-language press which defended the legality of the Grant administration's sale of surplus arms to France during the Franco-Prussian War.
