A racehorse that won its debut at Horseshoe Indianapolis this week will compete under a new name after the Jockey Club ruled that its original name, “Austrian Painter,” was potentially offensive because of its possible association with Adolf Hitler.

The horse won Monday, but the Jockey Club received a formal complaint about its name and opened a review. The organization ultimately determined that the name violated Rule 6.F.9.d, which bars registered horse names that are likely to be offensive or threatening based on factors including ethnicity, national origin, religion, or politics.

The horse’s owner and breeder, Scott Herbertson, appeared to suggest that “Austrian Painter” was instead a reference to Austrian artist Gustav Klimt. Hitler was born in Austria and studied art in Vienna before entering politics and eventually becoming Nazi Germany’s dictator.

The Jockey Club also ordered the horse’s full sister, originally named “New Order,” to be renamed. The phrase has an obvious connection to the British rock band, but it was also used in reference to Nazi Germany’s plans for Europe during World War II. Herbertson defended the name on social media, writing that New Order was his favored band.

“Austrian Painter” will now be known as “Merrylegs.” The Jockey Club said it takes complaints about potentially offensive names seriously and reviews them under its registration rules.

The organization has taken similar action in the past. In 2019, the Jockey Club ordered a horse named “Noose” to be renamed after determining that the name could reference lynching. The horse was subsequently registered as “Scabbard.”
