What do The Little Mermaid, Thumbelina, The Emperor's New Cloth and The Ugly Duckling all have in common? They are all the work of Hans Christian Andersen, one of literature's most famous children's authors.
Today, on what would have been his 205th birthday, Google is celebrating his life's accomplishments with not one, but a series of five different Google doodles, each depicting one of his famous stories.
The Danish poet and author definitely deserves the Google treatment: H.C. Andersen is responsible for some of most cherished fairy tales of all time. The Princess and the Pea, The Snow Queen, and dozens of his other stories have become essential components of our childhoods.
Google's been cranking out the Google Doodles in the last year. Most recently, Google celebrated Pi Day and math nerds everywhere.
Here's a compilation of all of the Google Doodles celebrating Hans Christian Andersen. Can you guess which stories each logo commemorates? Make your guesses in the comments.
