Franz Joseph Gall
German neuroanatomist whose skull-reading method, later called phrenology, was discredited
German physician and neuroanatomist who argued that the mind has separate faculties housed in different parts of the brain. His skull-reading method, later called phrenology, was not supported, but the localisation idea fed later neuroscience.
Why this person matters
Gall is taught as an early, flawed version of the idea that mental functions have places in the brain. The localisation idea largely survived; reading faculties from skull bumps did not. Johann Spurzheim, his dissection assistant and later rival, coined the name phrenology and lectured in Paris, London and Boston.
Main contributions
Localisation of mental faculties
He held that the mind consists of separate faculties housed in the brain, and he proposed 27 of them. A Hektoen International article says his general ideas of functional localisation were later shown to be largely correct.
Cranioscopy
He claimed that skull shape reflected the brain beneath and could be read for faculties. This method, which Spurzheim later named phrenology, linked mental organs to bumps on the skull, which is its central error.
A new dissection method
He moved away from random slicing to slow exploration of the whole brain and the separation of individual fibres.
Context and limits
Marie-Jean-Pierre Flourens, asked by the Paris Academy of Sciences to investigate on Napoleon's order, did crude experiments mostly on birds and argued the brain acts as a whole. An 1815 Edinburgh Review article called the work thorough quackery, and Austrian authorities saw it as a threat to public morality. Phrenological ideas were later used to justify discrimination.

Biological bases of behaviour.Appears in history and biological chapters as the standard example of a discredited method that contained a lasting idea: that functions are localised in the brain.
