Known as The Man in Black, Cash became one of biggest influences on 20th century music for his iconic voice and songs with emotional resonance.
He began singing at age five while working on his parents' cotton farm, and felt tremendous guilt after a head saw mortally wounded his older brother Jack.
The actor Joaquin Phoenix portrayed Cash in the biopic film, Walk the Line.
He married Vivian Liberto on August 7, 1954, and after their divorce in August 1966, he married June Carter Cash on March 1, 1968.
Reese Witherspoon played the role of his wife and fellow country singer, June Carter Cash, in the film Walk the Line.
