JACKSON, Miss. — A son of legendary Mississippi blues artist Robert Johnson became rich by winning a court fight over his father’s estate. But even when finances were no longer a concern, an attorney said, Claud Johnson kept the gravel truck he had driven for years — a reminder of the hard work that guided his life.

Claud Johnson was 83 when he died Tuesday, said John Kitchens, who represented him in the extended legal battle over the estate of Robert Johnson.

The Mississippi Supreme Court ruled in early 2014 that Mr. Johnson could keep the profits from the only two known photographs of his father. Legend has it that Robert Johnson, who wrote ‘‘Me and the Devil Blues’’ and ‘‘Crossroads Blues,’’ sold his soul to the devil for his talent.
