Wilhelm von Lenz (born 20 May 1809 in Riga - died 7 January 1883 in Saint Petersburg) was a Baltic German Russian official and writer.
 Wilhelm von Lenz was a friend of many mid-century Romantic composers, including Franz Liszt, Frédéric Chopin and Hector Berlioz, Lenz's most important and influential work was an early biography of the German composer Ludwig van Beethoven, entitled "Beethoven et ses trois styles" (1855), written in response to the disparagement of Beethoven by Alexander Ulybyshev in his "Nouvelle biographie de Mozart" (1843).
 Lenz promoted the idea (already suggested by earlier figures such as François-Joseph Fétis) that Beethoven's musical style be divided into three characteristic periods.
 Lenz's periodisation, with minor changes, is still widely used today by musicologists in discussing Beethoven's compositions.

The Beethoven Project Trio is an American piano trio that was formed in Chicago in 2008.
 Its founding members are pianist George Lepauw, violinist Sang Mee Lee and cellist Wendy Warner.
 The first public concert given by the trio was on March 1, 2009 at Chicago’s Murphy Auditorium for the world premiere of a recently rediscovered piano trio by (Hess 47) Ludwig van Beethoven, as well as the American premiere of another Beethoven trio (Anhang 3) and the Chicago premiere of yet another Trio (Opus 63); the performance also included the well-known “Archduke” Trio by Beethoven.
 John von Rhein, music critic of the Chicago Tribune, wrote about the trio's first concert that "for musicians who had never worked together as a trio before, pianist George Lepauw, violinist Sang Mee Lee and cellist Wendy Warner made a splendid ensemble, playing with finely judged balance, evenness of sound and unanimity of style [...] Lepauw, Lee and Warner ended their program with Beethoven’s familiar “Archduke” Trio, a masterpiece that drew fully on their individual and collective abilities.
 The slow movement emerged with particular eloquence here."
During the course of his lifetime (1770–1827), Ludwig van Beethoven enjoyed relationships with many of his musical contemporaries.
 Beethoven was famously difficult to get along with, and the history of his relationships with contemporaries is littered with arguments, misunderstandings, and reconciliations.
 Beethoven had well-known fallings out with his one-time teacher, Joseph Haydn, with the piano virtuoso and composer Johann Nepomuk Hummel, and the German composer Carl Maria von Weber.
Ferdinand Ries (28 November 1784 [baptised] – 13 January 1838) was a German composer.
 Ries was a friend, pupil and secretary of Ludwig van Beethoven.
 He composed eight symphonies, a violin concerto, eight piano concertos, three operas, and numerous other works in many genres, including 26 string quartets.
 In 1838 he published a collection of reminiscences of his teacher Beethoven, co-written with Franz Wegeler.
 The symphonies, some chamber works—most of them with piano— his violin concerto and his piano concertos have been recorded, demonstrating a style which is, unsurprising due to his connection to Beethoven, somewhere between those of the Classical and early Romantic eras.
The Beethoven "Gesamtausgabe" is the first collected edition of the works of Ludwig van Beethoven.
 Its full title is "Ludwig van Beethovens Werke: vollständige kritisch durchgesehene überall berechtige Ausgabe" (which roughly translated means "Ludwig van Beethoven's Works: complete, critical, thoroughly revised, authorized edition").
 It was published between 1862 and 1865, with a supplementary volume appearing in 1888.
Ludwig van Beethoven the Elder, also Ludovicus van Beethoven and Lodewijk van Beethoven (January 5, 1712 – December 24, 1773) was a professional singer and music director, best known as the grandfather of the composer Ludwig van Beethoven.
Ludwig van Beethoven ( , ; ] ; baptised 17 December 177026 March 1827) was a German composer and pianist.
 A crucial figure in the transition between the Classical and Romantic eras in Western art music, he remains one of the most famous and influential of all composers.

Ludwig van (full title: "Ludwig van: A report"; German: "Ludwig van: ein Bericht") is a black-and-white German film by Mauricio Kagel.
 Filmed in 1969, it was first screened the following year.
 The work was commissioned by Westdeutscher Rundfunk for the bicentennial celebrations of the birth of Ludwig van Beethoven in 1970.
 The film examines the reception of the composer and his works and how he has become a consumer product of the culture industry.
 The soundtrack is an arrangement of fragments of Beethoven's works, modified as if heard by the deaf composer himself; it is distinct from Kagel's 1970 composition "Ludwig van".
 Prominent contemporary artists including Dieter Roth, Stefan Wewerka (), Robert Filliou, and Joseph Beuys were involved in the design.
 According to "Gramophone", "at first it’s a laugh a minute ... then Kagel's film turns dark".
