Jean Marie Marcel Albert Pitres (26 August 1848 – 25 March 1928) was a French neurological physician.
He was born in Bordeaux and received his training in Paris, where he was the student of Jean Martin Charcot (1825–1893) and Louis-Antoine Ranvier (1835–1922).
In the late 1870s, with Charles-Émile François-Franck, he performed studies on the excitation of the cerebral cortex and the localization of brain function.
Lessons that Pitres gave at the amphitheater in Bordeaux on the following subjects were compiled and published: hysteria and hypnotism (1891), amnesic aphasia (1897), paraphasia (1898) and physical signs associated with pleural effusions (1902).
[2] With Leo Testut (1849–1925), he was co-author of Les nerfs en schémas, anatomie et physiopathologie (1925).
