implied that "Negroes" were a creational rank between "Greeks" and chimpanzees Nott took up the theory that
malaria and
yellow fever were caused by parasitic infections with "
animalcules" (microorganisms), earlier held by
John Crawford. In his 1850
Yellow Fever Contrasted with Bilious Fever he attacked the prevailing
miasma theory. He is often credited as being the first to apply the
insect vector theory to
yellow fever, then a serious health problem of the
American South. Nott believed that mixed-race relationships between people of European and African descent would lead to the "probable extermination of the two races" because mulattoes would live shorter lives, be more susceptible to disease, and less fertile — but that more data was needed to prove the claim. Citing Nott's need,
Kentucky Senator
Joseph R. Underwood had the racial category of "mulatto" added to the
1850 United States census. Morton's followers, particularly Nott and
George Gliddon (1809–1857) in their monumental tribute to Morton's work,
Types of Mankind (1854), carried Morton's ideas further and claimed and backed up his findings, which supported the notion of
polygenism, which claims that humanity originates from different ancestral lineages and is the ancestor of the
multiregional hypothesis. In their book, Nott and Gliddon argued that the races of mankind each occupied distinct zoological provinces and did not originate from a single pair of ancestors; they both believed God had created each race and positioned each race in separate geographic provinces. The doctrine of zoological provinces outlined in
Types of Mankind did not allow for "superiority" of one type of race over another; each type was suited to its own province, and was superior within its own province. At the same time, though, Nott concluded that "Caucasian races . . . are influenced by several causes in a greater degree than other races," including "the largest brains and the most powerful intellect." Similarly, Nott claimed that, because the races were created in different provinces, all races must be of equal antiquity. Here, however, Nott used "race" to signify something "pure and permanent," a distinct and specific "type" that faced "extermination" if "mixed" with another "type." Nott's concept of racial purity greatly informed the twentieth century racial theories employed by the Nazi regime. Moreover, Nott and other polygenists, such as Gliddon, believed that the name of the biblical
Adam meant "to show red in the face" or "
blusher" in Hebrew; since supposedly only light-skinned people could blush, the biblical Adam must have been of the
Caucasian race. Nott persistently attacked the scientific basis of the
Bible and also rejected the
theory of evolution by claiming that the environment does not change any organism into another, and also rejecting
common descent. Nott believed monogenism was "absurd" and had no biblical or scientific basis. He pointed to excavations in Egypt that depicted animals and humans as they looked today to refute monogenism and evolution. According to Nott, the monuments and artifacts found in Egypt proved that the "White, Mongolian and Negro existed at least five thousand years ago." Nott claimed that this proved beyond dispute that each race had been created separately. was interpreted by them wrongly since the "one blood" of Paul's sermon included only the nations that he knew existed, which were local. In 1857, Nott and Gliddon again co-edited a book,
Indigenous Races of the Earth. That book built upon the arguments in
Types of Mankind that linked anthropology with "scientific" studies of race to establish a supposed natural hierarchy of the races. The book included chapters from
Louis Ferdinand Alfred Maury,
J. Atkin Meigs, and Francis Polszky, letters from
Louis Agassiz, Joseph Leidy, and A.W. Habersham.
Charles Darwin opposed Nott and Gliddon's polygenist and
creationist arguments in his 1871
The Descent of Man, arguing for a monogenism of the human species. Darwin conceived the common origin of all humans (aka
single-origin hypothesis) as essential for
evolutionary theory. Darwin cited Nott and Gliddon's arguments as an example of those classing the races of man as separate species; Darwin disagreed and he concluded that humanity is one species. Nott was a founder of the
Medical College of Alabama, established in Mobile in 1859, and served as its professor of surgery. In 1860 he successfully appealed to the
state legislature for a monetary appropriation and a state charter for the school. During the
American Civil War, he served as a
Confederate surgeon and
staff officer. During the early years of the war, he served as director of the Confederate General Army Hospital in Mobile; later, he served in the field as medical director on the staffs of Brig. Gen.
Daniel Ruggles and Gen.
Braxton Bragg, and as hospital inspector. He lost both of his remaining sons to the war. Upon his own death in 1873, he was interred at
Magnolia Cemetery in Mobile. ==Honors==
