Alonso Álvarez de Pineda [SEP] Introduction
Alonso Álvarez de Pineda (; Aldeacentenera, 1494 – 1520) was a Spanish Conquistador and cartographer who was first in Texas history. In 1519, he led several expeditions to map the westernmost coastlines of the Gulf of Mexico, from the Yucatán Peninsula to the Pánuco River, just mapped parts of Florida, which he believed to be an island. Antón de Alaminos' exploration eliminated the western areas as being the site of the passage, leaving the land between the Pánuco River and Florida to be mapped. Alaminos persuaded the governor of Santiago, Francisco de Garay, to finance an expedition to search the remainder of the Gulf.
