Paul Broca

Broca, Paul (1824-1880)   Paul Broca is best known for his discovery that the brain has a specific area responsible for speech. Broca hypothesized that his patient’s aphasia was caused by a brain lesion. After the patient died (of unrelated causes), Broca performed an autopsy and found a lesion on the third frontal convolution of the left cerebral hemisphere. This portion of the brain which controls speech is called “Broca’s area” More of a clinician than experimenter, Broca taught surgical pathology in Paris, founded a society of physical anthropology, and served in the French Senate.
