Spanish explorer Juan Díaz de Solís was born c.1470, and was one of the first to enter the Río de la Plata estuary in South America.

Chief pilot of the Spanish navy, he was killed and eaten by the Charrua Indians, along with most of his crew, after sailing up the Uruguay River in the 1500s. He was attempting to make his way to the Indies via the Uruguay and Panama rivers.
