Hans Christian Andersen was a Danish author, fairy tale writer, and poet, who wrote many fairy tales that Disney adapted from to make films and shorts, like The China Shop (based on The Shepherdess and the Chimney Sweep), The Ugly Duckling, the 1989 animated film, The Little Mermaid, Piano Concerto No. 2, a segment in Fantasia 2000 (based on The Steadfast Tin Soldier), The Little Matchgirl, the 2013 animated film, Frozen, and its sequel inspired by The Snow Queen. One of his other stories, Ole Lukøje, was adapted into a 1944 Walt Disney's Little Library storybook, Through the Picture Frame.
- The names of Frozen's characters were inspired by conducting an internet search for Norwegian baby names. While completely unintentional, a fan put together the fact that Hans, Kristoff, Anna, and Sven sound like "Hans Christian Andersen".
- He is alluded to in Frozen II when Elsa sees her parents in the past as adolescents. Her father King Agnarr is reading a book under a tree prompting her mother Iduna to ask what he's reading. Agnarr responds by saying it's "Some new Danish author", clearly referring to the author of Frozen's source-material. It does however create an inconsistency with real-world history as Frozen II takes place following the year 1840 and that the flashback took place decades earlier when the future king and queen were adolescent. In real-life, Andersen's first published novel was in 1829.
- He is the first author to meet his creation in a TV episode, followed by Edgar Rice Burroughs, who wrote Tarzan.
- Some of his fairy tales that Disney adapted from to make films and shorts won five Academy Awards: The Ugly Duckling won an Academy Award for Best Original Short, The Little Mermaid's song, "Under the Sea" won Academy Awards for Best Original Song and Best Original Score. Frozen (while not an adaptation, merely inspired by "The Snow Queen") won two Academy Awards for Best Animated Feature and its song, "Let It Go" for Best Original Song.
