12095 Pinel           Discovered 1998 Apr. 25 by E. W. Elst at the European Southern Observatory.
Philippe Pinel (1745-1826), a French physician who made revolutionary contributions to the treatment of patients suffering from mental illness, became chief physician at the La Salpêtrière clinic in Paris. His Traité médico-philosophique sur l´Aliénation mentale (1801) has been translated into several languages.
