Quem foram os Irmãos Doppler...?

Franz and Karl Doppler (1821-1883, 1825-1900)

Franz and Karl Doppler were both born in Lemberg (the modern Lvov, in Ukraine), where their Austrian father, a composer and oboist, was an Imperial regimental musician. The brothers were taught the flute by their father and drew public notice for their rapid progress on the instrument. After temporary stays in Warsaw and Bucharest,the family settled in Budapest in 1838 where both brothers found positions as flutists and assumed parallel careers as composers and performers.
The brothers toured the musical centers of Europe performing their compositions of virtuoso fantasias and paraphrases for two flutes to great acclaim. The Doppler's compositions,sometimes written together, reflect the tastes of the period. They make great use of Hungarian themes, whether in Variations sur un air hongrois or Fantaisie sur des motifs hongrois, or in the famous Fantaisie pastorale hongroise.Transcriptions and pot-pourris on melodies from operas were highly prized by the public, forms to which Liszt, Glinka and many other composers contributed.
In an excerpt of his review of an 1855 Viennese concert by the Dopplers, critic Eduard Hanslick writes: "The flute playing of the Doppler brothers is among the most distinguished that we can remember in the field of instrumental virtuosity".
In 1858 Franz took a post in Vienna as first ballet-conductor (and resident ballet composer ) at the Vienna Opera and as professor at the Vienna Conservatory, and Karl held various posts as principal flute and composer until 1865 where he served as Kapellmeister in Stuttgart for the next 33 years.
