Fascinating website about the friend and pupil of Chopin, who edited many of Chopin's posthumous works. http://www.julianfontana.com/biography/biography.html
Thanks for the link! We must never forget that without the help of Fontana some significant compositions of Chopin might be never found or published. I can't imagine a world without the fantasie-impromptu :lol:. The only pity is that Fontana's editions are very often different from Chopin's manuscript, and I don't know which to believe and follow.
