The brain area that coordinates the muscles used in speech is in the left frontal lobe and is known as Broca's area. Paul Broca identified this region after studying patients who could understand language but had great difficulty producing fluent speech. Autopsy of those patients showed damage to a specific part of the left frontal cortex, linking this area to speech production and giving it Broca’s name. This localization explains why damage to this region produces nonfluent, effortful speech (Broca’s aphasia) while comprehension can remain relatively intact. By contrast, Carl Wernicke pinpointed a region involved in language comprehension (Wernicke’s area) in the left temporal lobe, Phineas Gage’s case taught us about the frontal lobe’s role in personality and behavior, and the hippocampus is primarily linked to memory. So, the figure associated with discovering the brain area for speech muscle coordination is Paul Broca.
