Williams, "Johann David Schoepf and His Contributions to North American Geology," Bulletin Geological Society of America, Vol. 5 (1893).The first edition of Schopf's account of his travels along the eastern coast of America immediately following the Revolutionary War along with the extremely rare first edition of his work on American mineralogy. The author was a German-trained physician who served as a field surgeon attached to the Ansbach regiment of Hessian mercenaries employed by the British during the American Revolution. After the war, Schopf stayed an additional two years in America, travelling from New York City south to St. Augustine, Florida. He also spent time in the Bahamas. Schopf was a careful student of natural history, and was particularly interested in the geology and mineralogy of the region. The BEYTRAGE is a very important book, the product of his geological observations along the east coast. Howes refers to the REISE as the "first notable 18th century account of the United States by a German traveller" and calls the BEYTRAGE the "first consequential work on American geology." He was the author of the earliest MATERIA MEDICA based on plants found in eastern North America.
