The son of a naturalist, William Bartram (1739–1823) was commissioned to undertake a tour of south-eastern North America in 1773. Collecting seeds, taking specimens and making meticulous drawings and observations of previously unknown flora and fauna, his four-year expedition took him from the foothills of the Appalachians, through Florida and on to the Mississippi. First published in 1791, within ten years this account had been translated into German, French and Dutch. A unique historical record now, and of particular interest at the time, his accounts of the Seminole, Creek and Cherokee Indians were seen by contemporaries as being sympathetic towards peoples commonly regarded as little better than savages, but his writings persuaded others of the need for a more humane approach to the indigenous people. This work influenced not only scientists, but writers such as Wordsworth and Coleridge, and it remains a classic of American science, history and literature.
