Patty S. Hill co-wrote "Happy Birthday to You" with her sister Mildred J. Hill in 1893, originally titled "Good Morning to All." The song was designed as a simple classroom greeting for young children, reflecting Patty's deep understanding of early childhood music education and her commitment to creating accessible, joyful material for beginners.
The Hills' melody became one of the most recognizable songs in the world, adopted across generations and cultures. Patty's legacy as an educator shaped how music teachers approach teaching melody and community singing to the youngest learners.
