The Berkeleys re-create the life of the colonial Quaker who became George IIIs botanist for North America, from his childhood in sparsely settled Pennsylvania in the early 1700s, his Quaker schooling, his friendship with Benjamin Franklin, and his growing interest in botany, ecology, and better methods of farming.
Bartrams pioneering excursions took him as far north as Lake Ontario, west to Pittsburgh, and south through the Carolinas and Georgia to Florida. He was often accompanied by his son, William, who was to become a famous botanist also. Maps and drawings of people, plants, and places in Bartrams life enrich the text, and extracts from his extensive correspondence reveal the exchange of plants, seeds, animals, and fossils as well as ideas with other colonials who, with Bartram and Franklin, would found the American Philosophical Society.
