Among the first to identify the brain as the major controlling center for the body were
Hippocrates and his followers, inaugurating a major change in thinking from
Egyptian, biblical and early Greek views, which based bodily primacy of control on the heart. This belief was supported by the Greek physician
Galen, who concluded that mental activity occurred in the brain rather than the heart, contending that the brain, a cold, moist organ formed of sperm, was the seat of the animal soul—one of three "souls" found in the body, each associated with a principal organ. The Swiss pastor
Johann Kaspar Lavater (1741–1801) introduced the idea that
physiognomy related to the specific character traits of individuals, rather than general types, in his
Physiognomische Fragmente, published between 1775 and 1778. His work was translated into English and published in 1832 as
The Pocket Lavater, or, The Science of Physiognomy. He believed that thoughts of the mind and passions of the soul were connected with an individual's external frame. Of the forehead, When the forehead is perfectly
perpendicular, from the hair to the eyebrows, it denotes an utter deficiency of understanding. (p. 24) In 1796 the German physician
Franz Joseph Gall (1758–1828) began lecturing on organology: the isolation of mental faculties and later
cranioscopy which involved reading the skull's shape as it pertained to the individual. It was Gall's collaborator
Johann Gaspar Spurzheim who would popularize the term "phrenology". In 1809 Gall began writing his principal work,
The Anatomy and Physiology of the Nervous System in General, and of the Brain in Particular, with Observations upon the possibility of ascertaining the several Intellectual and Moral Dispositions of Man and Animal, by the configuration of their Heads. It was not published until 1819. In the introduction to this main work, Gall makes the following statement in regard to his doctrinal principles, which comprise the intellectual basis of phrenology: Through careful observation and extensive experimentation, Gall believed he had established a relationship between aspects of character, called
faculties, with precise
organs in the
brain. Johann Spurzheim was Gall's most important collaborator. He worked as Gall's
anatomist until 1813 when for unknown reasons they had a permanent falling out. Publishing under his own name Spurzheim successfully disseminated phrenology throughout the
United Kingdom during his lecture tours through 1814 and 1815 and the
United States in 1832 where he would eventually die. Gall was more concerned with creating a physical science, so it was through Spurzheim that phrenology was first spread throughout
Europe and America. Phrenology, while not universally accepted, was hardly a fringe phenomenon of the era.
George Combe would become the chief promoter of phrenology throughout the English-speaking world after he viewed a brain dissection by Spurzheim, convincing him of phrenology's merits. The popularization of phrenology in the middle and working classes was due in part to the idea that scientific knowledge was important and an indication of sophistication and modernity. Cheap and plentiful
pamphlets, as well as the growing popularity of scientific lectures as entertainment, also helped spread phrenology to the masses. Combe created a system of philosophy of the human mind that became popular with the masses because of its simplified principles and wide range of social applications that were in harmony with the liberal Victorian world view. George Combe's book
On the Constitution of Man and its Relationship to External Objects sold more than 200,000 copies through nine editions. Combe also devoted a large portion of his book to reconciling religion and phrenology, which had long been a sticking point. Another reason for its popularity was that phrenology balanced between free will and
determinism. A person's inherent faculties were clear, and no faculty was viewed as evil, though the abuse of a faculty was. Phrenology allowed for self-improvement and upward mobility, while providing fodder for attacks on aristocratic privilege. Phrenology also had wide appeal because of its being a reformist philosophy not a radical one. Phrenology was not limited to the common people, and both Queen Victoria and Prince Albert invited George Combe to read the heads of their children. The American brothers Lorenzo Niles Fowler (1811–1896) and
Orson Squire Fowler (1809–1887) were leading phrenologists of their time. Orson, together with associates
Samuel Robert Wells and Nelson Sizer, ran the phrenological business and publishing house
Fowlers & Wells in
New York City. Meanwhile, Lorenzo spent much of his life in England, where he initiated the famous phrenological publishing house L. N. Fowler & Co. and gained considerable fame with his
phrenology head (a
china head showing the phrenological faculties), which has become a symbol of the discipline. Orson Fowler was known for his
octagonal house. Phrenology came about at a time when scientific procedures and standards for acceptable evidence were still being codified. In the context of Victorian society, phrenology was a respectable scientific theory. The
Phrenological Society of Edinburgh founded by George and Andrew Combe was an example of the credibility of phrenology at the time, and included a number of extremely influential social reformers and intellectuals, including the publisher
Robert Chambers, the astronomer
John Pringle Nichol, the evolutionary environmentalist
Hewett Cottrell Watson, and asylum reformer
William A. F. Browne. In 1826, out of the 120 members of the Edinburgh society an estimated one third were from a medical background. By the 1840s there were more than 28 phrenological societies in London with more than 1,000 members. Another important scholar was
Luigi Ferrarese, the leading Italian phrenologist. He advocated that governments should embrace phrenology as a scientific means of conquering many social ills, and his
Memorie Riguardanti La Dottrina Frenologica (1836), is considered "one of the fundamental 19th-century works in the field". During the early 20th century, a revival of interest in phrenology occurred, partly because of studies of
evolution,
criminology and
anthropology (as pursued by
Cesare Lombroso). The most famous British phrenologist of the 20th century was the
London psychiatrist
Bernard Hollander (1864–1934). His main works,
The Mental Function of the Brain (1901) and
Scientific Phrenology (1902), are an appraisal of Gall's teachings. Hollander introduced a quantitative approach to the phrenological diagnosis, defining a method for measuring the skull, and comparing the measurements with statistical averages. In Belgium,
Paul Bouts (1900–1999) began studying phrenology from a pedagogical background, using the phrenological analysis to define an individual
pedagogy. Combining phrenology with
typology and
graphology, he coined a global approach known as
psychognomy. Bouts, a
Roman Catholic priest, became the main promoter of renewed 20th-century interest in phrenology and psychognomy in Belgium. He was also active in
Brazil and
Canada, where he founded institutes for characterology. His works
Psychognomie and ''Les Grandioses Destinées individuelle et humaine dans la lumière de la Caractérologie et de l'Evolution cérébro-cranienne
are considered standard works in the field. In the latter work, which examines the subject of paleoanthropology, Bouts developed a teleological and orthogenetical view on a perfecting evolution,'' from the paleo-encephalical skull shapes of
prehistoric man, which he considered still prevalent in
criminals and savages, towards a higher form of mankind, thus perpetuating phrenology's problematic racializing of the human frame. Bouts died on March 7, 1999. His work has been continued by the Dutch foundation PPP (
Per Pulchritudinem in Pulchritudine), operated by Anette Müller, one of Bouts' students. During the 1930s, Belgian colonial authorities in
Rwanda used phrenology to explain the purported superiority of
Tutsis over
Hutus. == Application ==
