Hermann Frischbier (1823 – 1891) was a German schoolteacher as well as an author of works about East Prussian local history and culture.
Growing up in the house of a bricklayer where they spoke Low German, he was familiar with the language, customs and practices of East Prussia.
His articles appeared in the Altpreußischen Monatsschrift ("Old Prussian Monthly"), the Zeitschrift für deutsche Philologie ("Journal for German Philology"), in Die deutschen Mundarten ("The German Dialects"), the Korrespondenzblatt des Vereins für niederdeutsche Sprachforschung ("Magazine of the Association for Low German Language Research"), the Wissenschaftlichen Monatsblättern ("Scientific Monthly") and the folklore journals, Am Urdsbrunnen and Am Urquell.
Along with many other colleagues, Frischbier significantly promoted Prussian folklore.
Through [Frischbier's works], the treasure of the Old Prussians in proverbs, rhymes and provincialisms is exhaustively covered.The Masurian, Jan Karol Sembrzycki, made famous Frischbier's contribution to Polish folklore - even "the times of the most ferocious Polish oppression" - although Frischbier had barely mastered the Polish language himself.
