by Fritz Pistorius
Fritz Pistorius was the pen name of the German writer Robert Eule Andreas Robert Eule. Reference sources list him as born on October 15, 1864, in Prettin/Lichtenburg, and as having died on November 17, 1932, in Berlin.
Library and biographical records connect the name Fritz Pistorius with German popular and juvenile literature, and public-domain catalogues show that his work has continued to circulate long after his lifetime. That combination suggests a writer whose books were part of the broad reading culture of his era, especially for younger audiences.
Although detailed biographical information appears to be limited in the sources I could confirm, the basic record is clear: Fritz Pistorius was a pseudonym used by Robert Eule, a German author active around the late 19th and early 20th centuries.
