Authorship and Original Title
The song was written by sisters Patty Hill and Mildred J. Hill, who were American educators and composers. They created the melody and lyrics as a classroom greeting titled "Good Morning to All," which was first published in 1893 in the songbook "Song Stories for the Kindergarten" (source: Forbes).
The lyrics later evolved into the familiar birthday greeting, and the song became widely known as "Happy Birthday to You" in the early 20th century. The Hill sisters' original composition remains the foundation of the modern birthday song used globally.
Copyright History and Lawsuits
The copyright history of "Happy Birthday to You" has been complex and heavily litigated over the decades. Warner/Chappell Music claimed copyright ownership for years and collected licensing fees, but a federal judge ruled in 2015 that the copyright claim was invalid (source: Forbes).
The court found that the copyright registered by Warner/Chappell applied only to a specific piano arrangement and not to the song's lyrics or melody. As a result, the song entered the public domain, and the company stopped enforcing its copyright claims (source: Court Listener).
Current Status and Licensing
Today, "Happy Birthday to You" is in the public domain, meaning anyone can use it freely without paying royalties or obtaining a license. The song is one of the most recognized and frequently performed songs in the English language, often ranking at the top of public domain and cultural heritage lists (source: Forbes).
Companies and media producers no longer need to secure special permission or pay fees to use the song in films, advertisements, or live events. The Hill sisters' original work remains the definitive version, and its public domain status ensures continued, unrestricted use worldwide (source: U.S. Copyright Office).
