I have a test where I am given the following article, what is an answer for the question: What is the name of the person to whom Bartok dedicated the First Rhapsody for violin and orchestra (or piano) of 1928? ?

Szigeti was an avid champion of new music, and frequently planned his recitals to include new or little-known works alongside the classics. Many composers wrote new works for him, notably Béla Bartók, Ernest Bloch, and Eugène Ysaÿe, along with lesser-known composers such as David Diamond and Hamilton Harty.
The reason for Szigeti's appeal to composers was articulated by Bloch upon completion of his Violin Concerto: the concerto's premiere would have to be delayed a full year for Szigeti to be the soloist, and Bloch agreed, saying that Modern composers realize that when Szigeti plays their music, their inmost fancy, their slightest intentions become fully realized, and their music is not exploited for the glorification of the artist and his technique, but that artist and technique become the humble servant of the music.
Szigeti was also the dedicatee of the first of Eugène Ysaÿe's Six Sonatas for Solo Violin; in fact, Ysaÿe's inspiration to compose the sonatas came from hearing Szigeti's performances of J.S. Bach's Six Sonatas and Partitas, to which they are intended as a modern counterpart.Perhaps Szigeti's most fruitful musical partnership was with his friend Béla Bartók. The first piece Bartók dedicated to him was the First Rhapsody for violin and orchestra (or piano) of 1928; the rhapsody, based on both Romanian and Hungarian folk tunes, was one of a pair of violin rhapsodies written in 1928 (the other being dedicated to Zoltán Székely.) In 1938, Szigeti and clarinetist Benny Goodman teamed up to commission a trio from Bartók: originally intended to be a short work just long enough to fill both sides of a 78 rpm record, the piece soon expanded beyond its modest intent and became the three-movement Contrasts for piano, violin and clarinet. In 1944, by which time Szigeti and Bartók had both fled to the United States to escape the war in Europe, Bartók's health was failing and he had sunk into depression. He was in dire need of money, but felt no inspiration to compose and was convinced that his works would...
