9. He wrote numerous plays, librettos, essays and travelogues, three autobiographies and 168 fairy tales. His stories are translated in about 150 languages. In his days he was famous as some sort of rock star. He was dining with kings and befriended with many contemporary celebrities as Richard Wagner, Charles Dickens, Victor Hugo and Franz Liszt.
Despite that he really never felt to be accepted in high society. This can be felt in many of his fairy tales through irony, mocking and bitterness. Thumbelina, Ugly Duckling, Nightingale and others all carry a lot of his life experiences in them.
10. Hans Christian Andersen never married. He was in love several times and he was attracted to both sexes but just couldn't find a proper partner for at least some time. His most famous unfulfilled love was famous opera singer Jenny Lind who was more attracted to famous composers as Mendelssohn and Chopin.
He remained single all of his life. Andersen's health deteriorated three years before his death when he felt of bed and never fully recovered. Soon after that he got bronchitis and symptoms of liver cancer. He expected the end and helped to prepare music for his funeral. He said: "Most of people who will walk behind my coffin will be children, so keep the beat of the music with short steps."
