Jan Ladislav Dussek was a Czech classical composer and virtuoso pianist. He was an important representative of Czech music abroad in the second half of the 18th century and the beginning of the 19th century. Some of his more forward-looking piano works have traits often associated with Romanticism.

Ludwig van Beethoven's Piano Sonata No. 26 in E♭ major, Op. 81a, known as Les Adieux, was written during the years 1809 and 1810. This sonata was influenced by Jan Ladislav Dussek's sonata with the same nickname.
