Franziska Freifrau von Reitzenstein, ne von Nyss, alias Franz von Nemmersdorf was a German novelist.
Von Reitzenstein was born the daughter of a judicial counselor in Castle Hrdenstein in Swabia. She was well educated and moved in aristocratic and noble circles. In 1849 she married the royal Bavarian Rittmeister Freiherr von Reitzenstein. After her husband died in 1853, she travelled to several places of Italy and was inspired to write by Karl Gutzkow. She randomized her male pen name Franz in a topographical, statistical lexicon, whereas Nemmersdorf was the former name of a settlement in East Prussia, today Mayakovskoye.
