Jan Ladislav Dussek (more properly Václav Jan Dusík) (February 12, 1760 in ?áslav-March 20, 1812 in St.-Germain-en-Laye) was a Czech composer and pianist.
The Dussek family has an extraordinarily long history as professional musicians, starting at least as early as Jan Ladislav's grandfather, and lasting in the Moravian branch of the family at least into the 1970s. Of them, Jan Ladislav is often known as "Dussek the Great". Jan Ladislav's mother was a harpist, and he composed much music for the harp as well as for the piano. Great as his music may be, his personal life (in which harpists figured prominently) was the stuff of which movies are made.
