John Mitchell was born in 1711 in Lancaster County, Virginia to a relatively well off merchant and planting family. He went to Scotland to study at the University of Edinburgh, earning the M.A. in 1729, then studying medicine until 1731 but without receiving the M.D. He then returned to Virginia to practice medicine; by 1735 he had set up his practice at Urbanna. In his spare time he studied natural history and became known as a botanist. He was elected to the original American Philosophical Society in 1744. In 1745 Mitchell argued that a series of epidemics occurring in Virginia were due to unsanitary troop ships from Britain. Mitchell and his wife, Helen, suffered themselves from ill health. So in 1746 they moved to Britain's milder climate. En route, their ship was captured by a French privateer; although they were released, their belongings were confiscated and they arrived in London with only Mitchell's small fund of investments to their name. Mitchell did not try to compete with the metropolitan doctors; instead, he established himself as an expert on exotic botany. He was elected as a fellow of the Royal Society in November 1748, his candidature citation describing him as "A Gentleman of great merit and Learning, who Some time Since communicated to the Royal Society a very curious dissertation concerning the Colour of the skin in Negroes, and who from his long residence in Virginea, & from his great application to the Study of Natural history, especially Botany, is very well acquainted with the vegetable productions of North America, being desirous of being admitted a fellow of the Royal Society, is recommended by us from our personal knowledge of him as highly deserving the Honour he desires, as we believe he will be a usefull and valuable member of our Body." He continued to live in London, often touring the country estates of his aristocratic friends/patrons, occasionally writing articles and pamphlets, and living the life of a gentleman of modest means. His wife probably died soon after they reached London; Mitchell himself died in 1768.
Mitchell's ''Map of the British and French Dominions in North America'' (1755)
Mitchell's main claim to historical fame is his large map of the NorthAmerican colonies that was first published in London in 1755. This map is described in detail in the entry, Mitchell Map.
Racial studies
Mitchell wrote a paper in 1744 called An Essay upon the Causes of the Different Colours of People in Different Climates, submitted to the Royal Society in London by his correspondent Peter Collinson. In the paper, Mitchell claimed that the first race on earth had been a brown and reddish colour. He wrote "that an intermediate tawny colour found amongst Asiatics and Native Amerindians" had been the “original complexion of mankind”, and that other races came about by the original race spending generations in different climates.
