sentences:  In 1890, influenced by Pyotr Ilyich Tchaikovsky, Dvořák also visited Russia, and conducted performances of his music in Moscow and St. Petersburg.In 1891, Dvořák received an honorary degree from the University of Cambridge, and was offered a position at the Prague Conservatory as professor of composition and instrumentation.At first he refused the offer, but then later accepted; this change of mind was seemingly a result of a quarrel with his publisher Simrock over payment for his Eighth Symphony.
