question: Which composer was born first, Antonio Salieri or Hans Werner Henze?
answer: Antonio Salieri
context: Title: Boulevard Solitude
  Passage: Boulevard Solitude is a "Lyrisches Drama " (lyric drama) or opera in one act by Hans Werner Henze to a German libretto by Grete Weil after the play by Walter Jockisch, in its turn a modern retelling of François Prévost's "Manon Lescaut".  The piece is a reworking of the Manon Lescaut story, already adapted operatically by Auber, Massenet and Puccini, and here relocated to Paris after the Second World War where, as is noted in Grove, the focus of the story moves away from Manon and towards Armand des Grieux.  It became Henze’s first fully-fledged opera.  The work stands out for its strong jazz influences, from a composer who had hitherto been associated with twelve tone technique.
  Title: Antonio Salieri
  Passage: Antonio Salieri (] ; 18 August 17507 May 1825) was an Italian classical composer, conductor, and teacher.  He was born in Legnago, south of Verona, in the Republic of Venice, and spent his adult life and career as a subject of the Habsburg Monarchy.
  Title: Hans Werner Henze
  Passage: Hans Werner Henze (1 July 1926 – 27 October 2012) was a German composer.  His large oeuvre of works is extremely varied in style, having been influenced by serialism, atonality, Stravinsky, Italian music, Arabic music and jazz, as well as traditional schools of German composition.  In particular, his stage works reflect "his consistent cultivation of music for the theatre throughout his life".
  Title: Requiem (Henze)
  Passage: Hans Werner Henze composed the nine Sacred Concertos that comprise his Requiem over the course of three years from 1991 to 1993 on commissions from the London Sinfonietta, Suntory Corporation for the NHK Philharmonic, and Westdeutscher Rundfunk, Cologne.  The first movement, "Introitus: Requiem Aeternam" was commissioned by the London Sinfonietta as part of a memorial concert for Artistic Director Michael Vyner who died on 20 October 1989.  In addition to Henze, the London Sinfonietta also commissioned seven other prominent composers (Luciano Berio, Sir Harrison Birtwistle, Sir Peter Maxwell Davies, Toru Takemitsu, Oliver Knussen, and Nigel Osborne) to write works in Vyner's memory to make up the program which was performed on the 6 May 1990.
  Title: L'Upupa und der Triumph der Sohnesliebe
  Passage: L'Upupa und der Triumph der Sohnesliebe (English: "The Hoopoe and the Triumph of Filial Love") is an opera by Hans Werner Henze with a German libretto by the composer, inspired by Arab and Persian legends.  This is Henze's 15th, and self-stated final, opera, and the first where he has written his own libretto.
  Title: El Cimarrón (Henze)
  Passage: El Cimarrón (The Runaway Slave) is a composition by the German composer Hans Werner Henze, written when the composer lived in Cuba in 1969-1970.  It is subtitled "Biographie des geflohenen Sklaven Esteban Montejo" "(Biography of the runaway slave Esteban Montejo)", and the libretto by Hans Magnus Enzensberger is based on the oral autobiography related in 1963 to Miguel Barnet by Montejo, who was also a veteran of the Cuban War of Independence (1895-98).
  Title: We Come to the River
  Passage: We Come to the River – Wir erreichen den Fluss is an opera by Hans Werner Henze to an English-language libretto by Edward Bond.  Henze and Bond described this work as "Actions for music", rather than an opera.  It was Henze's 7th opera, written originally for the The Royal Opera in London, and takes as its focus the horrors of war.  The opera was first performed at the Royal Opera House, Covent Garden, London on 12 July 1976, with the composer as producer, Jürgen Henze as director, and David Atherton conducting.  It was subsequently staged at the Deutsche Oper Berlin, and received its first American performance at Santa Fe Opera in 1984, conducted by Dennis Russell Davies.
  Title: Symphony No. 1 (Henze)
  Passage: Hans Werner Henze's Symphony No. 1 was premiered in Darmstadt in 1947.  The premiere was hit by Henze’s accustomed bad luck.  The orchestral parts, handwritten by the composer himself, had become illegible during photocopying in Schott’s offices and despite the young composer’s best efforts to ink in the parts throughout the night, only the slow movement was performed.  The whole symphony was eventually premiered a year later, although Henze himself conducted the work only after comprehensive revision.
  Title: Das verratene Meer
  Passage: Das verratene Meer ("The Betrayed Sea") is an opera in two parts and 14 scenes, with music by Hans Werner Henze to a German libretto by Hans-Ulrich Treichel, after Yukio Mishima's novel "The Sailor Who Fell from Grace with the Sea".  Composed between 1986 and 1989, it was Henze's 9th opera, his third that he wrote for the Deutsche Oper in Berlin.
  Title: Ondine (ballet)
  Passage: Ondine is a ballet in three acts created by the choreographer Sir Frederick Ashton and composer Hans Werner Henze.  Ashton originally produced Ondine for the Royal Ballet in 1958, with Henze commissioned to produce the original score, published as "Undine", which has since been restaged by other choreographers.  The ballet was adapted from a novella called "Undine" by Friedrich de la Motte Fouqué and it tells the tale of a water nymph who is the object of desire of a young prince named Palemon.  The première of the ballet took place at the Royal Opera House, London, on 27 October 1958, with the composer as guest conductor.  The first major revival of this Ashton/Henze production took place in 1988.
