In the early 20th century Jerzy Żuławski was probably the most popular Polish science fiction author, with his Lunar Trilogy ("Trylogia księżycowa"), a masterpiece for its time and place of composition. Similar works were created by Tadeusz Konczyński, Wacław Gąsiorowski and Maria Julia Zaleska. In the reborn Second Polish Republic other writers followed in this genre. Edmund Kruger and Kazimierz Andrzej Czyżowski were known for his many books addressed to the younger audience; Bruno Winawer for his satirical take and Jerzy Rychliński and Ferdynand Antoni Ossendowski for their catastrophic vision of future war. Finally, Antoni Słonimski's "Dwa końce świata" "(Two Ends of the World)" is perhaps the best known dystopian work of the time.
