Anton Arensky
In March 1885, Nadezhda von Meck asked Tchaikovsky to use his good offices to find Pachulski's younger brother Henryk a teaching position at the Moscow Conservatory. Henryk had been studying there since 1880 under Nikolai Rubinstein, Anton Arensky and others. Tchaikovsky's efforts came to nothing but Henryk did succeed in gaining a position there the following year.
