The first true ragtime composition was published by William Krell called The Mississippi Rag in 1897. Tom Turpin, the first published African American composer wrote The Harlem Rag the same year.
And that, as they say, is another story. Scott Joplin (1868-1917), an American composer and pianist, was one of the most important developers of ragtime music. Some regard him as as the originator, however musical history clearly shows that the elements of Ragtime were in place well before Joplin entered the scene.
