Pitié and La Salpêtrière, both founded in the17th century, were for long two distinct hospitals until they merged in 1964. The name La Salpêtrière is inherited from the initial purpose of the buildings designed to produce saltpeter for gun powder. But the place was soon transformed into an asylum to shelter the poor and the insane. From the care of this underprivileged population, alienists such as Pinel have paved the way for modern medicine for the mentally ill at the time of the French Revolution. In the second half of the 19th century, Jean‐Martin Charcot and his students laid the foundations of modern neurology from the observation of the large population hosted in La Salpêtrière, mostly women with severe chronic diseases. Charcot led clinicopathological studies in almost all the fields of nervous system disorders. His successors (including Raymond, Dejerine, Pierre Marie) maintained the same close relationship between clinical neurology and neuropathology. In parallel with the development of neurosurgery at Pitié hospital, neuropathology first spread through small laboratories attached to clinical departments. The merger of the two hospitals in the early '60s coincided with the creation of a large university hospital in which the care and study of diseases of the nervous system were preponderant. An independent laboratory of neuropathology was created, led by Raymond Escourolle. This period was on the eve of important developments in neuroscience around the world. Today, the Pitié‐Salpêtrière neuropathology laboratory still plays a central role between neurology and neurosurgery clinics and major research institutes such as the Brain Institute, callled Institut du Cerveau et de la Moelle (ICM), and the Institute of Myology.
