While we all know the words to "Happy Birthday," not many of us know the song's interesting history! According to urban legend, the song was first written by two sisters from Kentucky named Patty and Mildred Hill in the late 1890s.
Instead of singing to celebrate birthdays, the song was actually written to welcome in the morning! The transition from "Good morning to you" to "Happy birthday to you" was not exactly documented, but roughly 30 years passed before the birthday version was first recorded.
In fact, it was composer Robert H. Coleman who included the "Happy Birthday" lyrics in his songbook for the very first time. Now "Happy Birthday" is sung at almost every single birthday celebration -- followed by the blowing out of the candle, of course!
So, after the family was done singing "Happy Birthday," the girls watched eagerly as Dad got ready to blow out the candles. With a gentle puff, he blew them out in one try.
