Phrenology (from Greek: φρήν, phrēn, “mind”; and λόγος, logos, “knowledge”) is a pseudoscience primarily focused on measurements of the human skull, based on the concept that the brain is the organ of the mind, and that certain brain areas have localized, specific functions or modules (see modularity of mind). Phrenology was especially popular from about 1810 until 1840. Following the materialist notions of mental functions originating in the brain, phrenologists believed that human conduct could best be understood in neurological rather than abstract terms. It is now considered a pseudoscience. Developed by German physician Franz Joseph Gall in 1796, the discipline was very popular in the 19th century. The principal British centre for phrenology was Edinburgh, where the Edinburgh Phrenological Society was established in 1820. In 1843, François Magendie referred to phrenology as “a pseudo-science of the present day.”
