Thomas Jefferson Farnham

Thomas Jefferson Farnham (1804–1848) was an explorer and author of the American West in the first half of the 19th century. His travels included interaction with missionary Jason Lee, and he later led a wagon train on the Oregon Trail. While in Oregon Country he wrote a petition to federal authorities that requested federal protection of the region from the United States government, which was signed by many of the local settlers who had come from the United States.
