The first European explorer to visit the Mississippi River was Hernando de Soto. He was exploring for Spain in 1541 when his crew became the first Europeans to have a written account of the Mississippi River. However, he died of an illness about a year later during the same expedition.
Hernando de Soto, famed Spanish explorer of the Americas in the Colonial Period, died in the year 1542 (on May 21st). His death was apparently caused by a fever of some kind, and he breathed his last somewhere in what is now known as Arkansas or Louisiana. (The precise place of his death is not clear from the historical records available.)
Hernando de Soto's family was noble but also poor. He lived at the family manor, and his family wanted him to become a lawyer. However, in 1514, he told his family he wished to be an explorer instead of a lawyer. He went on to join the expedition of Francisco Pizarro who conquer the Peruvian empire in 1532. He was born about the year 1500 and died in 1542.
It is impossible to give you a precise date, as all records of his birth have been lost. Nor can we give you a precise year, the nearest estimate/guess is 1496 or 97.
