Eric Jarosinski (born 1971) is an American Germanist, author, humorist, and public speaker.

[1] Jarosinski writes under the nom de plume NeinQuarterly on the social networking site Twitter, where he writes linguistic, political, and philosophical aphorisms, keeping to the 140-character limit.

He then made the jump to print with a weekly column in the leading German weekly Die Zeit (2014–present) and the Dutch daily NRC Handelsblad (2015-2016)[3] Jarosinski's first book Nein.

A Manifesto was released in 2015 and has been published in English, German, Spanish, Italian, Dutch, and Danish.

[5] After study and dissertation research in Berlin as a German Chancellor Fellow (Alexander von Humboldt Foundation), Jarosinski completed his Ph.D. at the University of Wisconsin–Madison in 2005 with a dissertation on "transparency" as a political aesthetic and highly fraught ideological program.
