Question: Violin Sonata No. 2 was first publicly performed by the musician and composer of what nationality?

Context paragraphs:
Clara Schumann: Clara Schumann ("née" Clara Josephine Wieck; 13 September 1819 – 20 May 1896) was a German musician and composer, considered one of the most distinguished pianists of the Romantic era.  She exerted her influence over a 61-year concert career, changing the format and repertoire of the piano recital and the tastes of the listening public.  Her husband was the composer Robert Schumann.  Together they encouraged Johannes Brahms.  She was the first to perform publicly any work by Brahms.  She later premiered some other pieces by Brahms, notably the "Variations and Fugue on a Theme by Handel".

Violin Sonata No. 2 (Schumann): The Sonata for Violin and Piano No. 2 in D minor Op. 121 by Robert Schumann was completed in November 1851, Dedicated to the violinist Ferdinand David, the sonata received its first public performance from Clara Schumann and Joseph Joachim on October 29, 1853 in Düsseldorf, in a concert that marked the beginning of a long term musical collaboration.

Violin Sonata No. 2 (Prokofiev): Sergei Prokofiev's Violin Sonata No. 2 in D Major, Op. 94a (sometimes written as Op. 94bis), was based on the composer's own Flute Sonata in D, Op. 94, written in 1942 but arranged for violin in 1943 when Prokofiev was living in Perm in the Ural Mountains, a remote shelter for Soviet artists during the Second World War.  Prokofiev transformed the work into a violin sonata at the prompting of his close friend violinist David Oistrakh.  It was premiered on 17 June 1944 by David Oistrakh and Lev Oborin.

Violin Sonata (Janáček): Violin Sonata, a composition for violin and piano, is a work of the Czech composer Leoš Janáček (1854-1928).  It was written in the summer of 1914, but it was not Janáček’s first attempt to create such a composition.  He resolved to compose a violin sonata already as a student at the conservatoire in Leipzig in 1880, and later during his studies in Vienna.  His early sonatas are today lost.

Violin Sonata No. 2 (Beethoven): The Violin Sonata No. 2 of Ludwig van Beethoven in A major, the second of his Opus 12 set (along with his Violin Sonata No. 1 and Violin Sonata No. 3), was written in 1797-8 and dedicated to Antonio Salieri.  It has three movements:

Violin Sonata No. 5 (Beethoven): The Violin Sonata No. 5 in F major, Opus 24, is a violin sonata by Ludwig van Beethoven.  It is often known as the "Spring Sonata" ("Frühlingssonate"), and was published in 1801.  Its dedicatee was Count Moritz von Fries, a patron to whom Beethoven also dedicated two other works of the same year—the C major string quintet and the fourth violin sonata—as well as his later seventh symphony.

Violin Sonata No. 4 (Beethoven): The Violin Sonata No. 4 of Ludwig van Beethoven in A minor, his Opus 23, was composed in 1801, published in October that year, and dedicated to Count Moritz von Fries.  It followed by one year the composition of his first symphony, and was originally meant to be published alongside Violin Sonata No. 5, however it was published on different sized paper, so the opus numbers had to be split.  Unlike the three first sonatas, Sonata No. 4 received a favourable reception from critics.

Violin Sonata No. 3 (Hill): Violin Sonata No. 3 in A minor, Stiles 1.2.1.6 So3, is a sonata for violin and piano by Alfred Hill.  Its music originates from his "Piano Trio in A minor, Stiles 1.2.2.1 TrA" (probably 1890s).  It has no precise dating, but was obviously finished after "Violin Sonata No. 2" (January 1906): most probably in 1907.  It was performed ion 6 July 1908 at the YMCA Hall in Sydney by Cyril Monk (the dedicatee of Hill's previous sonata) and Constance Brandon Usher.  Hill later arranged this sonata for flute and piano (the so-called "Flute Sonata No. 2 in A minor, Stiles 1.2.1.1 SoA2").

Violin Sonata No. 1 (Beethoven): Ludwig van Beethoven's Violin Sonata No. 1 in D major is a violin sonata from his Opus 12 set, along with his Violin Sonata No. 2 and Violin Sonata No. 3.  It was written in 1798 and dedicated to Antonio Salieri.  Being an early work written around the period when Beethoven studied with Haydn, the sonata is for the most part written in a classical style much like that of Mozart or Haydn.

Violin Sonata (Dvořák): The Sonata for Violin and Piano, op.57, in F Major (Czech: "Sonata F dur pro housle a klavír" ), is a violin sonata by Antonín Dvořák.  The work was composed between 3rd and 17th March 1880.  At the time, Dvořák was also working on his violin concerto, and it seems that the composer explored different aspects of the violin in the two pieces.  The sonata is naturally the more intimate of the two works, and appears in places to be influenced by Johannes Brahms.
