The Conflagration (German: "Der rote Hahn" , 1901) is a German play written by Gerhart Hauptmann (1862–1946).
 Like Henrik Ibsen, Hauptmann focuses attention on social issues.
 Unlike "The Weavers" (1892) and "The Assumption of Hannele" (1893), it does not seem to have ever been performed on Broadway; however, it was adapted as a German film in 1962, directed by John Olden and starring Rudolf Platte as Schuhmachermeister Fielitz and Inge Meysel as Frau Fielitz.
The Beaver Coat (German: Der Biberpelz ) is a 1928 German silent comedy film directed by Erich Schönfelder and starring Ralph Arthur Roberts, Lucie Höflich and Wolfgang von Schwindt.
 It is based on Gerhart Hauptmann's play "The Beaver Coat".
 It was made by the German subsidiary of First National Pictures.
Gerhart Johann Robert Hauptmann (15 November 1862 – 6 June 1946) was a German dramatist and novelist.
 He is counted among the most important promoters of literary naturalism, though he integrated other styles into his work as well.
 He received the Nobel Prize in Literature in 1912.
The Rats is a stage drama in five acts by Gerhart Hauptmann, which premiered in 1911, one year before the author received the Nobel Prize for Literature.
 Unlike other Hauptmann plays, such as "The Weavers" (1892) and "The Assumption of Hannele" (1893), this one does not seem ever to have been performed on Broadway.

The Ascension of Little Hannele (German: "Hanneles Himmelfahrt" ), also known simply as "Hannele", is an 1893 play by the German playwright Gerhart Hauptmann.
 In contrast to Hauptmann's naturalistic dramas, "The Assumption of Hannele" adopts a more symbolist dramaturgy and includes a dream sequence.
 The play is the first in recorded world literature with a child as its heroine.
 It was first published in 1894.
 Hauptmann was awarded the Grillparzer Prize in 1896 for the play.
Drayman Henschel (German: "Führmann Henschell" ), also known as "Carter Henschel", is an 1898 five-act naturalistic play by the German playwright Gerhart Hauptmann.
 Unlike his 1892 play "The Weavers", Hauptmann focuses on the story's psychological rather than social dimensions.
 As with his 1902 play "Rose Bernd", the play charts the demise of an ordinary man who falls victim to circumstances beyond his control.
 As with many of Hauptmann's dramas, it ends with the main character's suicide.
The Weavers (German: "Die Weber" , Silesian German: "De Waber" ) is a play written by the German playwright Gerhart Hauptmann in 1892.

Air Apparent is the thirty-first book of the Xanth series by Piers Anthony, which was first mentioned in the "Author's Note" in "Currant Events".
