Question: Which was premiered first, Candide or Siegfried?
Context: Dr. Siegfried Günter (8 December 1899 – 20 June 1969) and Walter Günter (8 December 1899 – 21 September 1937) were German twin brothers and pioneering aircraft designers.  Walter was responsible for the world's first rocket-powered and turbojet airframes, projects funded by Nazi Germany.  Siegfried was the father of the "thrust modulation theory". Switzerland has had its current boundaries since 1815, but maps of the Old Swiss Confederacy were drawn since the 16th century.  The first topographical survey on a federal level began in 1809, resulting in the Topographic Map of Switzerland (German: "Topographische Karte der Schweiz") or Dufour Map (German: "Dufourkarte"; French: "Carte Dufour").  From 1869 to 1901, this map was replaced by the Topographic Atlas of Switzerland (German: "Topographischer Atlas der Schweiz") or Siegfried Map (German: "Siegfriedkarte"; French: "Carte Siegfried"). Siegfried is a heavy metal band from Austria that was founded in 1998 by Bruder Cle, aka Hagen, who was later joined by Daniel Bachmaier (ex Sarcasm Syndrome), a.k.a. Ortwin, and former Dreams of Sanity singer Sandra Schleret.  In 2000 they released a demo CD called "Fafnir".  Later in 2000 they were signed to Napalm Records, releasing their first album, "Drachenherz", in 2001.  Their second album, "Eisenwinter", was released in 2003.  The lyrics of Siegfried are based on and inspired by the "Nibelung" Saga. Siegfried, WWV 86C, is the third of the four music dramas that constitute "Der Ring des Nibelungen" ("The Ring of the Nibelung"), by Richard Wagner.  It premiered at the Bayreuth Festspielhaus on 16 August 1876, as part of the first complete performance of "The Ring" cycle. Candide Preis (originally called "Stadtschreiber Stipendium", later "Candide Preis") is the only one German-French Literary award, named for its French satire "Candide" (first published in 1759 by Voltaire). Since 1995 it's prize every year awarded by the Foundation Genshagen, the Literary Association Minden, the "Villa Gillet" (Lyon) and the Minister of Culture (France) to French and German contemporary authors. Candide is an operetta with music composed by Leonard Bernstein, based on the 1759 novella of the same name by Voltaire.  The operetta was first performed in 1956 with a libretto by Lillian Hellman; but since 1974 it has been generally performed with a book by Hugh Wheeler which is more faithful to Voltaire's novel.  The primary lyricist was the poet Richard Wilbur.  Other contributors to the text were John Latouche, Dorothy Parker, Lillian Hellman, Stephen Sondheim, John Mauceri, John Wells, and Bernstein himself.  Maurice Peress and Hershy Kay contributed orchestrations.  Although unsuccessful at its premiere, "Candide" has now overcome the unenthusiastic reaction of early audiences and critics and achieved enormous popularity.  It is very popular among major music schools as a student show because of the quality of its music and the opportunities it offers to student singers.

The original Siegfried Line (German: "Siegfriedstellung" ) was a First World War line of defensive forts and tank defences built by Germany in northern France during 1916–17 as a section of the Hindenburg Line.  In English the term "Siegfried Line" commonly refers to the "Westwall", the German term for a similar Second World War-era defensive line built further east during the 1930s opposite the French Maginot Line.  This line stretched more than 630 km and featured more than 18,000 bunkers, tunnels and tank traps.  The network of defensive structures stretched from Kleve on the border with the Netherlands, along the western border of the old German Empire, to the town of Weil am Rhein on the border to Switzerland.  It was planned in 1936 and built between 1938 and 1940. Candide, ou l'Optimisme, ( ; French: ] ) is a French satire first published in 1759 by Voltaire, a philosopher of the Age of Enlightenment.  The novella has been widely translated, with English versions titled Candide: or, All for the Best (1759); Candide: or, The Optimist (1762); and Candide: or, Optimism (1947).  It begins with a young man, Candide, who is living a sheltered life in an Edenic paradise and being indoctrinated with Leibnizian optimism (or simply "optimism") by his mentor, Professor Pangloss.  The work describes the abrupt cessation of this lifestyle, followed by Candide's slow, painful disillusionment as he witnesses and experiences great hardships in the world.  Voltaire concludes with Candide, if not rejecting optimism outright, advocating a deeply practical precept, "we must cultivate our garden", in lieu of the Leibnizian mantra of Pangloss, "all is for the best" in the "best of all possible worlds". Rudolf Sutermeister (May 7, 1802 – May 9, 1868) was a Swiss medical doctor for the poor.  He was also a businessman, a manufacturer, an early socialist and a socio-political writer.  He is considered one of the first native Swiss German socialists, together with Gustav Siegfried, Johann Jakob Treichler, and Karl Bürkli; however, unlike Siegfried, he is also considered a utopian.
