The 120 skulls collected by Franz Joseph Gall served as the primary data set for his development of cranioscopy, a method intended to map mental faculties to specific cranial configurations. Born in Tiefenbronn in 1758, the German physician pioneered research into the localization of brain functions, challenging contemporary understanding of human neuroanatomy through systematic observation and physical dissections.
Early Observation and Education
Gall was born into a prominent family in Tiefenbronn, Germany, and originally intended to join the priesthood. He deviated from this path to study medicine at the University of Strasbourg before completing his degree at the University of Vienna. Under mentors such as Johann Hermann and Maximilian Stoll, he emphasized naturalistic observation, a technique he applied while working at a lunatic asylum and during his private practice in Vienna.

Take the IQ test →Theory of Organology
Developing the theory of Organology, Gall proposed that the brain comprised multiple independent entities linked to specific behaviors. He categorized 27 fundamental faculties, including mechanical ability and talent for poetry. He argued that the physical shape of the skull provided a reliable map of these traits, provided that the skull circumference exceeded 14 inches. His reliance on this external configuration became known as phrenology.
Professional Partnerships and Exile
In 1800, Gall hired Johann Spurzheim as an assistant, eventually elevating him to a full research partner. Their collaboration ended in 1813 when Spurzheim moved to Britain, leading Gall to accuse him of plagiarism. Gall faced significant opposition from the Austrian government, which labeled his theories materialistic and a threat to morality, forcing him to leave his lecturer post in Vienna and eventually settle in Paris.
Anatomical Methodology
Beyond his phrenological work, Gall refined the science of dissection. He abandoned the practice of random slicing, opting instead for a slow, detailed exploration of brain structure and the separation of individual fibers. He detailed his findings in his major work, On the Functions of the Brain and of Each of Its Parts. In 1823, his contributions were recognized by the Royal Swedish Academy of Sciences.

Questions readers ask
What is phrenology?
It is a method based on Gall's theory of Organology, which seeks to determine personality and mental faculties by examining the external shape and bumps of the human skull.
Why did Gall leave Austria?
The Austrian government considered his work materialistic and a threat to public morality, leading to the banning of his ideas and his departure to Paris.
