Władysław Pachulski
Władysław Pachulski (c. 1855 – 1919) was a Polish violinist, pianist and amateur composer who was the secretary to and later son-in-law of Nadezhda von Meck, the patroness for 13 years of Pyotr Ilyich Tchaikovsky. Pachulski was often the intermediary between composer and patroness, who had agreed never to meet face to face but to conduct an epistolary relationship. He played a significant role in the events surrounding the sudden break between them in 1890, and probably even instigated it.
He lived in Russia most of his adult life, where his name was rendered as Владислав Альбертович Пахульский (Vladislav Al'bertovich Pakhul'sky). He was the elder brother of the composer Henryk Pachulski.
