Juan Fioz

Brief Biography

Juan Fioz was born between 1514 and 1518 in Worms, Germany. He was perhaps the only German to join the Expedition. Prior to the Expedition he was a trumpeter and a member of Viceroy Mendoza's personal guard. Juan was present at the 1540 muster as a trumpeter. After the completion of the Expedition he returned to Mexico City as a trumpeter and participated in fellow expeditionary Luna y Arellano's expedition to La Florida in 1559. The documentary record still finds Juan in Mexico City in the 1580s.
