Naturalists Thomas Nuttall (1786–1859) and John Bradbury…
1804 CE to 1815 CE
Later, Nuthall will explore the Indian Territory (Oklahoma), the Oregon Trail, and (in 1834-35) even Hawaii.
His book A Journal of Travels into the Arkansas Territory is an important account of frontier life.
Although Nuthall is the most traveled Western naturalist before 1840, unfortunately most of his documentation and specimens are lost.
