From the Hans Christian Andersen biography "The Life of Hans Christian Andersen. Day By Day", written by DPhil Johan de Mylius:
1835The First Novel
In a letter (dated 16th) to Henriette Wulff, HCA mentions that he has just written some fairy-tales, and that H.C. Ørsted has told him:
"that if The Improvisatore brings me fame, then the fairy-tales will immortalise me. Of all my writing, they are the most accomplished, but I do not agree".
