Career
Many historians write that Pierre Luis was a Mexican-American but he was of French and Spanish (European) descent. In 1823, he became a fur man, receiving his first license to trade with the Pawnee. By the early 1830s he had shifted his operations to the mountains, a popular and active mountain man and trader.
Pierre Luis was nicknamed "Old Vaskiss" by other Mountain mentor
He traveled back and forth between the mountains and Saint Louis almost yearly, his reputation growing. Unable to turn a profit, they sold Fort Vasquez to Lock and Randolph in 1840 who subsequently went bankrupt and abandoned the structures in 1842.
Due to the bankruptcy, Luis Vasquez and Andrew Sublette could not collect the sum owed to them for the sale. Vasquez then became associated with Jim Bridger.
By 1843 they had built Fort Bridger on Blacks Fork of the Green River, which became as much an emigrant station as trading post.
Vasquez opened a store at Salt Lake City in 1855. He and Bridger sold their fort in 1858, but Vasquez already had retired to Missouri. He died at his Westport home, and was buried at Saint Mary"s Church cemetery.
