Patty Hill was a kindergarten principal in Louisville, Kentucky, developing various teaching methods at what is now the Little Loomhouse;[6] her sister Mildred was a pianist and composer.[7] The sisters used "Good Morning to All" as a song that young children would find easy to sing.[8] The combination of melody and lyrics in "Happy Birthday to You" first appeared in print in 1912, and probably existed even earlier.[9]
