In the main text we provide only the beginning of the extensive authentic dedication:
"à Mr Joseph Elsner
professeur à l'Université Royale de Varsovie
membre de la société philomatique de Varsovie
Chevalier de l'ordre de St Stanislas etc etc."
We omit the additional information about the addressee's position, function and honorary title, which is compliant with Chopin's practices used in other pieces, in which he mentioned only the addressee's title and surname, sometimes preceded by the name. It is unclear why the editions omitted the dedication – perhaps it was assumed that after Chopin's death and after 20 years from the date of creation of the Sonata the dedication was no longer relevant.
