11315 Salpêtrière           Discovered 1994 July 8 by E. W. Elst at Caussols.
Founded in Paris in 1862, "Salpêtrière Hospital" is a famous neurological clinic. Thanks to the clinician Jean-Martin Charcot, the clinic became one of the greatest neurological centers of the time in Europe. In 1885 Sigmund Freud visited Charcot and became interested in the psychological origins of neurosis.
