Samuel George Morton (January 26, 1799 – May 15, 1851) was an American physician, natural scientist, and writer who argued against the single creation story of the Bible, monogenism, instead supporting a theory of multiple racial creations, polygenism. He was a prolific writer of books on various subjects from 1823 to 1851. He wrote Geological Observations in 1828, and both Synopsis of the Organic Remains of the Cretaceous Group of the United States and Illustrations of Pulmonary Consumption in 1834. His first medical essay, on the use of cornine in intermittent fever, in 1825 was published in the Philadelphia Journal of the Medical and Physical Sciences. His bibliography includes Hybridity in Animals and Plants (1847), Additional Observation on Hybridity (1851), and An Illustrated System of Human Anatomy (1849). Early life and career Born in Philadelphia, Pennsylvania, Morton was raised as a Quaker and educated at Westtown School and the University of Pennsylvania, from where he graduated in 1820. He then earned an advanced degree from the University of Edinburgh, in Scotland, and began to practice medicine in Philadelphia in 1824. He was one of the founders of the Pennsylvania Medical College in Philadelphia and served as its professor of anatomy from 1839 until his resignation in 1843. He was elected a member of the American Philosophical Society in 1828 and the American Antiquarian Society in 1844. He is buried at Laurel Hill Cemetery, Philadelphia. "American School" ethnography Samuel George Morton is often thought of as the originator of "American School" ethnography, a school of thought in antebellum American science that claimed the difference between humans was one of species rather than variety and is seen by some as the origin of scientific racism. Morton argued against the single creation story of the Bible (monogenism) and instead supported a theory of multiple racial creations (polygenism). Morton claimed the Bible supported polygenism, and within working in a biblical framework his theory held that each race had been created separately and each was given specific, irrevocable characteristics. After inspecting three mummies from ancient Egyptian catacombs, Morton concluded that Caucasians and Negroes were already distinct three thousand years ago. Since the Bible indicated that Noah's Ark had washed up on Mount Ararat, only a thousand years ago before this, Morton claimed that Noah's sons could not possibly account for every race on earth. According to Morton's theory of polygenesis, races have been separate since
