The Wuppertal poets' circle (German: Wuppertaler Dichterkreis or Wupperbund) was a literary circle that existed during the 1850s, remaining active into the 1870s and 1880s. The core of the loosely-knit group consisted of seven poets born in or around Wuppertal, Germany: the merchants Reinhart Neuhaus , Emil Rittershaus, Friedrich Roeber, Adolf Schults, Wilhelm Wens, Carl Siebel, Karl Stelter,[1] and the bookseller Hugo Oelbermann. The circle "opposed gloomy Wuppertal Pietism with a free and joyful view of existence."[1]
