Anton Dvorak
From Memory Alpha, the free Star Trek reference
Antonín (or Anton) Dvořák was an Earth composer in the late 19th century. Dvořák's main focus was romantic music and wrote a series of musical compositions which he titled The Slavonic Dances.
When Captain Jean-Luc Picard called up his musical composition Picard Mozart trio, the music began to distort and turned into The Slavonic Dances. The cause of this was a malfunction in an interface between the USS Enterprise-D computer and Data, who engaged in a study of Dvorak's collected works, in 2369. (TNG: "A Fistful of Datas")
