Context: Johannes Brahms (7 May 1833  3 April 1897) was a German composer and pianist. Born in Hamburg into a Lutheran family, Brahms spent much of his professional life in Vienna, Austria. His reputation and status as a composer is such that he is sometimes grouped with Johann Sebastian Bach and Ludwig van Beethoven as one of the "Three Bs" of music, a comment originally made by the nineteenth-century conductor Hans von Bülow., Franz Liszt (born Franz Joseph Liszt) (in modern usage "Liszt Ferenc", ; October 22, 1811July 31, 1886) was a prolific 19th-century Hungarian composer, virtuoso pianist, conductor, music teacher, arranger, organist, philanthropist, author, nationalist and a Franciscan tertiary. , The Symphonie satellites were the first communications satellites built by France and Germany (and the first to use three-axis stabilization in geostationary orbit with a bipropellant propulsion system) to provide geostationary orbit injection and station-keeping during their operational lifetime. After the launch of the second flight model, they comprised the first complete telecommunications satellite system (including an on-orbit spare and a dedicated ground control segment). They were the result of a program of formal cooperation between France and Germany., Wilhelm Walter Friedrich Kempff ( 25 November 1895 -- 23 May 1991 ) was a German pianist and composer . Although his repertoire included Bach , Mozart , Chopin , Schumann , Liszt and Brahms , Kempff was particularly well known for his interpretations of the music of Ludwig van Beethoven and Franz Schubert . He recorded the complete collection of their piano sonatas . He is considered to have been one of the chief exponents of the Germanic tradition during the 20th century and one of the greatest pianists of all time ., Franz Peter Schubert (31 January 179719 November 1828) was an Austrian composer. Schubert died before his 32nd birthday, but was extremely prolific during his lifetime. His output consists of over six hundred secular vocal works (mainly Lieder), seven complete symphonies, sacred music, operas, incidental music and a large body of chamber and piano music. Appreciation of his music while he was alive was limited to a relatively small circle of admirers in Vienna, but interest in his work increased significantly in the decades following his death. Felix Mendelssohn, Robert Schumann, Franz Liszt, Johannes Brahms and other 19th-century composers discovered and championed his works. Today, Schubert is ranked among the greatest composers of the late Classical and early Romantic eras and is one of the most frequently performed composers of the early nineteenth century., Robert Schumann (8 June 181029 July 1856) was a German composer and influential music critic. He is widely regarded as one of the greatest composers of the Romantic era. Schumann left the study of law, intending to pursue a career as a virtuoso pianist. He had been assured by his teacher Friedrich Wieck that he could become the finest pianist in Europe, but a hand injury ended this dream. Schumann then focused his musical energies on composing., Subject: wilhelm kempff, Relation: country_of_citizenship, Options: (A) austria (B) germany (C) hamburg (D) teacher
