Scientific Achievements
William Dunbar was known for his engineering and scientific talents, which he employed in plantation work. He invented a screw press and introduced the square baling of cotton, and was the first to suggest the manufacture of cottonseed oil. He was Surveyor General for West Florida in 1798 and made the first meteorological observations in the Mississippi Valley in 1799. Dunbar built an astronomical observatory in Union Hill near his Natchez home and opened it to the public. His plantation home, "The Forest," became a meeting place for scholars; men such as naturalist William Bartram and ornithologist Alexander Wilson were frequent guests.
In 1799 Daniel Clark, US consul for New Orleans, introduced Dunbar to Thomas Jefferson (then Vice President) through a letter, saying "for Science, Probity & general information is the first Character in this part of the World". Through Jefferson, Dunbar would be introduced to the rest of the American scientific establishment. Dunbar never met Jefferson in person but the two corresponded for many years, and Jefferson asked him to lead the Red River expedition in 1804 and to organize another one in 1806. He was elected to the American Philosophical Society in 1800 and contributed twelve articles to the Society Transactions on subjects in natural history, astronomy and American Sign Language. In 1803 Dunbar, with others, established the Mississippi Society for the Acquirement and Dissemination of Useful Knowledge. After returning from the expeditions, and until his death in 1810, he devoted himself to scientific inquiry, gathering a significant collection of data on Indian vocabulary, as well as using chemical analysis in geology, seasonal river levels, fossils, astronomical phenomena, and utilizing a method of finding longitude by astronomical means.

Famous quotes containing the words scientific and/or achievements:
“There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.”
—Karl Marx (1818–1883)
“Our achievements speak for themselves. What we have to keep track of are our failures, discouragements, and doubts. We tend to forget the past difficulties, the many false starts, and the painful groping. We see our past achievements as the end result of a clean forward thrust, and our present difficulties as signs of decline and decay.”
—Eric Hoffer (1902–1983)
