Paul de Schlözer

On 3 February 1894, he performed the Chopin Cello Sonata with the visiting Czech cellist Hanuš Wihan, at the Conservatory.

[6] Some historians believe that de Schlözer was not the composer of these études at all, and, given their virtuosity, it is very intriguing why nothing else from his pen ever appeared, or why he did not achieve any sort of recognition as a major pianist himself.

The story goes that they were in fact written by Moszkowski, who lost the manuscript to de Schlözer in a card game, who published them as his own works.

2 is longer, more elaborate, and more technically demanding than the 11th of Moszkowski's 15 Études de Virtuosité, Op.

However, it may be that these similarities gave rise to the legend that de Schlözer pieces were written by Moszkowski.
