I want to know the answer to the following question:
Maurice Schlesinger and Camille Pleyel were what to Chopin?
All the background I'm provided with is that "Among modern scholarly editions of Chopin's works are the version under the name of Paderewski published between 1937 and 1966 and the more recent Polish "National Edition", edited by Jan Ekier, both of which contain detailed explanations and discussions regarding choices and sources.". Is that enough to answer the question?
Answer: no
