Career
Jarosinski writes under the nom de plume NeinQuarterly on the social networking site Twitter, where he writes linguistic and philosophical aphorisms, keeping to the 140-character limit. Jarosinski writes in German, Dutch and English. Jarosinski soon had a significant following, and made the jump to the print.
He has a weekly column in German weekly Die Zeit and also in Dutch daily National Research Council Handelsblad.
Jarosinski grew up in Park Falls, Wisconsin. As a child he had some exposure to the German language (Wisconsin having a large number of German Americans), but the interest in German culture and language really evolved after following a high school romantic interest there.
He consequently took up studies at the universities of Bonn, Frankfurt and Freiburg. He also studied at the University of Utrecht in the Netherlands, where he learned Dutch.
He completed his Doctor of Philosophy at the University of Wisconsin–Madison in 2005.
In 2007, he took up a position as Assistant Professor of German at the University of Pennsylvania. Jarosinski also treated works by Marx, Nietzsche and Kafka. In Spring of 2013 he withdrew his application for tenure.
He joined twitter in January 2012, and in the process became one of the first writers to use the smartphone as his primary writing instrument.
