Question: Ludwig Wenzel Lachnith was influenced by which Austrian "Father of the Symphony?"

full_context: Document 1: Hector Berlioz: Louis-Hector Berlioz (] (English: ); 11 December 1803 – 8 March 1869) was a French Romantic composer, best known for his compositions "Symphonie fantastique" and "Grande messe des morts" (Requiem). Berlioz made significant contributions to the modern orchestra with his "Treatise on Instrumentation". He specified huge orchestral forces for some of his works, and conducted several concerts with more than 1,000 musicians. He also composed around 50 songs. His influence was critical for the further development of Romanticism, especially in composers like Richard Wagner, Nikolai Rimsky-Korsakov, Franz Liszt, Richard Strauss, and Gustav Mahler.
Document 2: London symphonies: The London symphonies, sometimes called the Salomon symphonies after Johann Peter Salomon who introduced London to Joseph Haydn, were composed by Joseph Haydn between 1791 and 1795. They can be categorized into two groups: Symphonies Nos. 93–98, which were composed during Haydn's first visit to London, and Symphonies Nos. 99–104, composed in Vienna and London for Haydn's second visit.
Document 3: Piano Sonata Hob. XVI/34: The Piano Sonata in E minor, Hob. XVI/34, L. 53, was written in the late 1770s by Joseph Haydn and published in London around 1783 by Beardmore & Birchall.
Document 4: Symphony No. 80 (Haydn): The Symphony No. 80 in D minor, Hoboken 1/80, is a symphony composed by Joseph Haydn in 1784 as part of a trio of symphonies that also included symphonies 79 and 81. It is one of the relatively few later symphonies by Haydn to be in the minor mode. Symphony 80 is highly structured with both outer movements in sonata form. There is a common (though not strict) modulation pattern seen in all four movements.
Document 5: Wolfgang Amadeus Mozart: Wolfgang Amadeus Mozart ( ; ; ] ; 27 January 1756 – 5 December 1791), baptised as Johannes Chrysostomus Wolfgangus Theophilus Mozart, was a prolific and influential composer of the Classical era.
Document 6: Piano Sonata No. 3 (Beethoven): Ludwig van Beethoven's Piano Sonata No. 3 in C major, Op. 2, No. 3, is a sonata written for solo piano, composed in 1795. It is dedicated to Joseph Haydn and is often referred to as Beethoven's first virtuosic piano sonata. The three Opus 2 sonatas all contain four movements each, an unusual length which seems to show that Beethoven was aspiring towards composing a symphony. It is both the weightiest and longest of the three Opus 2 sonatas, lasting over 25 minutes, presenting many difficulties, including difficult trills, awkward hand movements, and forearm rotation. It is Beethoven's second longest piano sonata in his early period, only to Beethoven's Grand Sonata in E-flat Major, Op. 7, published a year later.
Document 7: Ludwig Wenzel Lachnith: Ludwig Wenzel Lachnith (Prague, July 7, 1746 – Paris, October 3, 1820) was a Bohemian horn player and versatile composer influenced by Joseph Haydn and Ignaz Pleyel.

Document 10: Joseph Haydn: (Franz) Joseph Haydn ( ; ] ; 31 March 173231 May 1809) was an Austrian composer of the Classical period.

Document 11: Wilhelm von Lenz: 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.
Document 12: Autobiographical sketch (Haydn): Joseph Haydn's Autobiographical sketch (1776) is the only autobiographical document ever prepared by this composer. Haydn wrote the sketch, which is about two pages long, at the request (relayed to him by a chain of two mutual acquaintances) of Ignaz de Luca, who was preparing a volume of brief biographies of Austrian luminaries entitled "Das gelehrte Oesterreich" ("Learned Austria"). The sketch was published in 1778, in Volume 1, Part 3 of this work. At the time of writing Haydn was 44 years old.

Document 15: Josef Mysliveček: Josef Mysliveček (9 March 1737 – 4 February 1781) was a Czech composer who contributed to the formation of late eighteenth-century classicism in music. Mysliveček provided his younger friend Wolfgang Amadeus Mozart with significant compositional models in the genres of symphony, Italian serious opera, and violin concerto; both Wolfgang and his father Leopold Mozart considered him an intimate friend from the time of their first meetings in Bologna in 1770 until he betrayed their trust over the promise of an operatic commission for Wolfgang to be arranged with the management of the Teatro San Carlo in Naples. He was close to the Mozart family, and there are frequent references to him in the Mozart correspondence.
