Question: Bernhard Stavenhagen and Franz Liszt, share which occupations?

Context paragraphs:
Walter Bache: Walter Bache ( ; 19 June 184226 March 1888) was an English pianist and conductor noted for his championing the music of Franz Liszt and other music of the New German School in England.  He studied privately with Liszt in Italy from 1863 to 1865, one of the few students allowed to do so, and continued to attend Liszt's master classes in Weimar, Germany regularly until 1885, even after embarking on a solo career.  This period of study was unparalleled by any other student of Liszt and led to a particularly close bond between Bache and Liszt.  After initial hesitation on the part of English music critics because he was a Liszt pupil, Bache was publicly embraced for his keyboard prowess, even as parts of his repertoire were questioned.

Hochschule für Musik Franz Liszt, Weimar: The University of Music FRANZ LISZT Weimar (in German: Hochschule für Musik Franz Liszt Weimar) is an institution of music in Weimar, Germany.

Lina Ramann: Lina Ramann (July 24, 1833 – March 30, 1912) was a German writer and teacher known for her books on the Hungarian composer and pianist Franz Liszt.  During 1874-94, she wrote his "official" though inaccurate three volume biography ""Franz Liszt, the artist and man"" (Franz Liszt als Künstler und Mensch) which was published between 1880-94.

Song Without End: Song Without End, subtitled The Story of Franz Liszt (1960) is a biographical film romance made by Columbia Pictures.  It was directed by Charles Vidor, who died during the shooting of the picture and was replaced by George Cukor.  It was produced by William Goetz from a screenplay by Oscar Millard, revised (uncredited) by Walter Bernstein and based on screenwriter Oscar Saul's original 1952 script (uncredited).  The music score was by Morris Stoloff and Harry Sukman with music by Franz Liszt, and the cinematography by James Wong Howe and Charles Lang (uncredited).  The film also featured music of those contemporaries of Liszt whom he unselfishly championed by featuring them in his numerous performances (e.g., Richard Wagner, Hector Berlioz, among others).

Héroïde funèbre (Liszt): Héroïde funèbre , S. 102, is a symphonic poem written by Franz Liszt in 1850 and published in 1857 as No. 8.  The work originated as the first movement of a planned "Revolutionary Symphony" inspired by the July Revolution.  Liszt pays homage in this programmatic symphonic poem to the soldiers and men that died fighting in revolutionary efforts.  The composition of this piece was started in 1830 as a brief sketch for a full symphony, but was dropped by Liszt in the continuing of other works.  However, in 1848, there was an uprising in Liszt's home country of Hungary.  One of Liszt's friends was killed during this revolution, which caused Liszt to revisit his now 20 year old sketch of the Revolutionary Symphony, shortening it and forming the first movement into the commemorative Héroïde funèbre.  Liszt said of the program, "In these successive wars and carnages, sinister sports, whatever be the colours of the flags which rise proudly and boldly against each other, on both sides they float soaked with heroic blood and inexhaustible tears.  It is for Art to throw her ennobling veil over the tomb of the brave, to encircle with her golden halo the dead and dying, that they may be the envy of the living."

Gustav Kastropp: Gustav Kastropp (30 August 1844 – 11 September 1925) was a German poet, librettist and musician.  Kastropp's texts were used by composers such as Georg Schumann, Eugen d'Albert and Bernhard Stavenhagen.

Hamlet (Liszt): Hamlet, S.104, is a symphonic poem by Franz Liszt, written in 1858 and published as No. 10.  It was not performed until 2 July 1876.  Like all but one of Liszt's 13 symphonic poems, "Hamlet" was written while Liszt was working in Weimar and is dedicated to Carolyne zu Sayn-Wittgenstein.  After viewing Bogumil Dawison play Hamlet in Weimar (1856), Liszt wrote: "He does not make him into an indecisive dreamer who collapses under the power of his mission, as he is regarded since Goethe's theory in "Wilhelm Meister", but much more as a gifted, enterprising prince with important political views who is waiting for the right moment to complete his work of revenge and come to the aim of his ambition, that is, to be crowned king in place of his uncle.  This goal can naturally not be reached in twenty-four hours and the clever anticipation which Shakespeare has put into the role of Hamlet and the negotiations with England which come clearly to the light of day at the end of the drama according to my view justify Dawson's interpretation, which Herr von Goethe and the aesthetes should not take too badly.  Regarding Ophelia, Liszt wrote: "She is loved by Hamlet, but Hamlet, like every exceptional person, imperiously demands the wine of life and will not content himself with the buttermilk.  He wishes to be understood by her without the obligation of explaining himself to her.  She collapses under her mission, because she is incapable of loving him in the way that he must be loved, and her madness is only the decrescendo of her feeling, whose lack of sureness has not allowed her to remain on the level of Hamlet."  Liszt's "Hamlet" is meant as a psychological study of the title character; only two brief references are made to Ophelia, both marked as "to be played as quietly as possible and sound like a shadowy picture."

Franz Liszt Academy of Music: The Liszt Ferenc Academy of Music (Hungarian: "Liszt Ferenc Zeneművészeti Egyetem" , often abbreviated as "Zeneakadémia", "Music Academy") is a concert hall and music conservatory in Budapest, Hungary, founded on November 14, 1875.  It is home to the Liszt Collection, which features several valuable books and manuscripts donated by Franz Liszt upon his death, and the AVISO studio, a collaboration between the governments of Hungary and Japan to provide sound recording equipment and training for students.  The Liszt Ferenc Academy of Music was founded by Franz Liszt himself (though named after its founder only in 1925, approx. 50 years after it was relocated to its current location at the heart of Budapest).  Between 1877-1879 the Academy moved into its present building, a masterpiece of art Neo-Renaissance architecture.
