Task: Question Generation
Input (English): Passage: Tchaikovsky's early separation from his mother caused an emotional trauma that lasted the rest of his life and was intensified by her death from cholera in 1854, when he was fourteen. The loss of his mother also prompted Tchaikovsky to make his first serious attempt at composition, a waltz in her memory. Tchaikovsky's father, who had also contracted cholera but recovered fully, sent him back to school immediately in the hope that classwork would occupy the boy's mind. Isolated, Tchaikovsky compensated with friendships with fellow students that became lifelong; these included Aleksey Apukhtin and Vladimir Gerard. Music, while not an official priority at school, also bridged the gap between Tchaikovsky and his peers. They regularly attended the opera and Tchaikovsky would improvise at the school's harmonium on themes he and his friends had sung during choir practice. "We were amused," Vladimir Gerard later remembered, "but not imbued with any expectations of his future glory". Tchaikovsky also continued his piano studies through Franz Becker, an instrument manufacturer who made occasional visits to the school; however, the results, according to musicologist David Brown, were "negligible".In 1855, Tchaikovsky's father funded private lessons with Rudolph Kündinger and questioned him about a musical career for his son. While impressed with the boy's talent, Kündinger said he saw nothing to suggest a future composer or performer. He later admitted that his assessment was also based on his own negative experiences as a musician in Russia and his unwillingness for Tchaikovsky to be treated likewise. Tchaikovsky was told to finish his course and then try for a post in the Ministry of Justice.
Output (English): What is the first name of the person who admitted that his assessment was also based on his own negative experiences as a musician in Russia?
