Who is the illistrator of The Little Mermaid?

The illustrator of the original "The Little Mermaid" story by Hans Christian Andersen was not credited. The story was first published in 1837, and illustrations were often added later by publishers or in subsequent editions.

However, the most famous and recognizable illustrations of "The Little Mermaid" are likely those done by Kay Nielsen for a 1914 edition. His art style is very distinct and has become synonymous with the story for many people.
