Did you know that the Happy Birthday song is translated into almost two dozen languages?
Guinness World Records once called it the most recognizable song in English.
Today is commonly celebrated as the anniversary of the song's publication, it likely wasn't published on today's date.
Rather, today is the birthday of the woman who wrote the song's melody.
A composer and educator, Mildred Hill was born on today's date in 1859.
She wrote the melody to "Good Morning to All," a greeting song written to be used in a classroom setting.
Her sister, a kindergarten teacher named Patty Smith Hill, wrote the lyrics that accompanied it.
