July 4 is important to U.S. history and on July 4, 1826, in addition to being the 50th Anniversary of the signing of the Declaration of Independence, it was also the date both Thomas Jefferson and John Adams died. It was also the birth date of Stephen Collins Foster.
Foster has been often cited as the father of American music and was the pre-eminent songwriter of the 19th century in the United States. He published his first song when he was only 18. His songs remain popular to this day, with such favorites as "Oh! Susanna," "Camptown Races," "Old Folks at Home" (known as "Swanee River"), "My Old Kentucky Home," and "Beautiful Dreamer." Foster was born and lived in what is now Pittsburgh (Lawrenceville). Doo Dah, Doo Dah!
