"Henry Sloan (January 1870 \u2013 13 March 1948?) was an African American musician, one of the earliest figures in the history of Delta Blues. Very little is known for certain about his life, other than he tutored Charlie Patton in the ways of the blues. There have been suggestions that he moved to Chicago shortly after World War I."@en . .
