Smith, Jedediah Strong (1798–1831) explorer, fur trader; born in Bainbridge, N.Y. Starting in the fur trade with Gen. William Ashley in St. Louis in 1822, he took over Ashley's Rocky Mountain trade in 1826 with two others. From 1826–30, he led exploratory expeditions from Great Salt Lake, Utah, across the Mohave desert into California, where he was nearly imprisoned by the Mexican governor. He then went north through the Sierras and along the Willamette River to Ft. Vancouver, Oregon, surviving an attack by the Umpqua Indians en route. In 1831 he was killed by Comanches after entering the Santa Fe trade. Because he did not write of his trips, he did not get credit for his achievements for many years; but he was, among other firsts, the first American to enter and exit California by the eastern route.
