安徒生 (Hans Christian Andersen) was a famous Danish author known for his fairy tales. Born on April 2, 1805, in Odense, Denmark, he became one of the most celebrated writers in children's literature. His stories, such as The Little Mermaid and The Ugly Duckling, often contain moral lessons and explore themes of love, acceptance, and transformation. Andersen's unique storytelling style and imaginative characters have made his works timeless classics. He published his first collection of fairy tales in 1835, which quickly gained popularity across Europe. Today, his stories continue to be adapted into various forms of media, including films, ballets, and stage productions.
