Es war einmal ("Once upon a time") is a fairy-tale opera in a prologue and three acts by the Austrian composer Alexander von Zemlinsky.

The Cherry Orchard (Russian: "Вишнëвый сад" , "Vishnevyi sad " ) is the last play by Russian playwright Anton Chekhov.
 Written in 1903, it was first published by "Znaniye" (Book Two, 1904), and came out as a separate edition later that year in Saint Petersburg, via A.F. Marks Publishers.
 It opened at the Moscow Art Theatre on 17 January 1904 in a production directed by Konstantin Stanislavski.
 Chekhov described the play as a comedy, with some elements of farce, though Stanislavski treated it as a tragedy.
 Since its first production, directors have contended with its dual nature.
 It is often identified as one of the three or four outstanding plays by Chekhov, along with "The Seagull", "Three Sisters", and "Uncle Vanya".

Der Kirschgarten (The Cherry Orchard) is an opera in four acts by the Swiss composer Rudolf Kelterborn.
 The German-language libretto was written by the composer and is based on Gudrun Düwel's German translation of Chekhov's play "The Cherry Orchard".

 The premiere production was conducted by Ralf Weikert and directed by Nikolaus Lehnhoff.

Otto Jolle Matthijs Jolles (1911–1968) performed a major service to strategic studies in the United States by providing the first American translation of Carl von Clausewitz's "magnum opus", "On War".
 Jolles himself is a bit obscure to students of military affairs, largely because his translation of "On War" was his only published effort in that field.
 Even his nationality has been misidentified—he has been variously identified as Hungarian, Czech, and Dutch.
 Military historian Jay Luvaas once quoted an unidentified Israeli professor as saying "whereas the first English translation was by an Englishman who did not know German, the 1943 American translation was by a Hungarian who did not know English."
 There is little in the Jolles translation to warrant such a comment.
 In the field of German literature, Jolles is quite well known, especially for his work on Friedrich Schiller.
 Most of his published work, however, is in German.
