|Claude Johnson, seated|
The blues legend Robert Johnson remains an enigma; for all but two pictures are known of him (a third one is under dispute and is most probably fake), he also never left a will, and died at a young age. Yet his music shook the foundations and spawned rock n' roll.
One of his sons, Claude Johnson, was announced dead at the age of 83 in Mississippi a few days ago. Claude was the sole heir of his father's music, and under a supreme court order in 2014 to also benefit from the photograph royalties, despite heavy class action suits from relatives.
However, he didn't use these royalties to build houses or whatever, rather taking menial jobs and living a simple life.
