Robert Leroy Johnson was born on May 8, 1911 and passed away on August 16, 1938. He was probably the most famous and influential of all the pre-war Delta blues musicians.
According to Wikipedia;
His landmark recordings from 1936–1937 display a remarkable combination of singing, guitar skills, and songwriting talent that have influenced generations of musicians. Johnson's shadowy, poorly documented life and death at age 27 have given rise to much legend.
