Franz Gall
- Distinguished grey vs. white
matter
– Described cases of aphasia
linked to lesions of frontal
lobes
– Proposed a general theory of
localization: “cranioscopy”, - later renamed “phrenology”
- localizing specific abilities and
character traits
-Gall eventually linked 27
human traits to bumps on skull
