Helena Nyblom (7 December 1843 – 9 October 1926) was a Danish-Swedish children's story author.
Helena was born in Copenhagen, Denmark, daughter to the Danish painter Jørgen Roed.
The stories, written in Danish and then translated into Swedish by her husband, were first published in the Ny Illustrerad Tidskrift (New Illustrated Journal) and subsequently collected in four volumes between 1875 and 1881.
In all she wrote more than 80 fairy tales, in which she mixed Swedish folklore, ancient myths and romantic motifs.
The conversion received great attention in the media and she endured much criticism in her circle of friends to have fallen for Rome.
