Benjamin Smith Barton (February 10, 1766 – December 19, 1815) was an American botanist, naturalist, and physician. He was one of the first professors of natural history in the United States and built the largest collection of botanical specimens in the country. He wrote the first American textbook on botany.

Early life
Barton's father, Rev. Thomas Barton, was an Irish immigrant from Carrickmacross who opened a school near Norristown, Pennsylvania, in 1751. His mother was Esther Rittenhouse, sister of astronomer David Rittenhouse.
Between 1780 and 1782, Barton studied at York Academy in Lancaster, Pennsylvania, where he showed an aptitude for drawing and an interest in collecting natural history specimens. Two years later, he attended the College of Philadelphia School of Medicine, studied medicine under Thomas Shippen, and attended Benjamin Rush's lectures in 1785. Young Barton also accompanied his uncle, David Rittenhouse, who had been commissioned to survey the western boundary of Pennsylvania in 1785. His travels aroused a lifelong interest in Native Americans. In 1786, Barton transferred to the University of Edinburgh, where he studied for two years before leaving without a degree because of financial difficulties and disagreements with two professors.
