It was during 1835 that Andersen published the first installment of his immortal Fairy Tales (Danish: Eventyr). More stories, completing the first volume, were published in 1836 and 1837. The quality of these stories was not immediately recognised, and they sold poorly. At the same time, Andersen enjoyed more success with two novels: O.T. (1836) and Only a Fiddler. His Specialty book that is still known today was the Ugly Duckling (1837).
