Born in Lyons, France, in the mid-18th century, Pedro (also Pierre) Vial moved to the United States around the 1860s or 1870s, living in Louisiana in 1779 and later among the Taovaya Indians. Upon moving to San Antonio, Texas, in 1784, Governor Domingo Cabello y Robles appointed Vial and Francisco Xavier Chaves to learn about the Comanche Indians. Two years later, the governor requested Vial find a direct route between San Antonio and Santa Fe, New Mexico. He and Cristóbal de los Santos traveled toward Waco and along the Red River, living again with the Taovayas. Vial finally arrived in Santa Fe in May 1787 and, after a year, began his return to San Antonio via Natchitoches, Louisiana. In addition to successive explorations in the Southwest, Vial acted as interpreter and agent for the governor of New Mexico in Native American areas and lived among the Comanches. In 1803, he moved to Santa Fe, where he died in 1814.
