BICHAT, See also:MARIE See also:FRANCOIS See also:XAVIER (1771–1802) , See also:French anatomist and physiologist, was See also:born at Thoirette (See also:Jura) on the 14th of See also:November 1771. His See also:father, a physician, was his first instructor. He entered the See also:college of Nantua, and afterwards studied at See also:Lyons. In See also:mathematics and the See also:physical sciences he made rapid progress, but ultimately devoted himself to the study of See also:anatomy and See also:surgery, under the guidance of M. A. See also:Petit (1766–1811), See also:chief surgeon to the Hotel Dieu at Lyons. The revolutionary disturbances compelled him to See also:fly from Lyons and take See also:refuge in See also:Paris in 1793. He there became a See also:pupil of P. J. See also:Desault, who was so strongly impressed with his See also:genius that he took him into his See also:house and treated him as his adopted son. For two years he actively participated in all the labours of Desault, prosecuting at the same See also:time his own re-searches in anatomy and See also:physiology. The sudden See also:death of Desault in 1795 was a severe See also:blow to Bichat.

His first care was to acquit himself of the obligations he owed his benefactor, by contributing to the support of his widow and her son, and by conducting to a See also:

close the See also:fourth See also:volume of Desault's See also:Journal de Chirurgie, to which he added a See also:biographical memoir of its author. His next See also:object was to reunite and See also:digest in one See also:body the surgical doctrines which Desault had published in various periodical See also:works. Of these he composed, CEuvres chirurgicales de Desault, au tableau de sa See also:doctrine, et de sa pratique clans le traitement See also:des maladies externes (1798–1799), a See also:work in which, although he professes only to set forth the ideas of another, he develops them with the clearness of one who is a See also:master of the subject. In 1797 he began a course of anatomical demonstrations, and his success encouraged him to extend the See also:plan of his lectures, and boldly to announce a course of operative surgery. In the following See also:year, 1798, he gave in addition a See also:separate course of physiology. A dangerous attack of haemoptysis interrupted his labours for a time; but the danger was no sooner past than he plunged into new engagements with the same ardour .as before. He had now See also:scope in his physiological lectures for a See also:fuller exposition of his See also:original views on the See also:animal See also:economy, which excited much See also:attention in the medical See also:schools at Paris. Sketches of these doctrines were given by him in three papers contained in the See also:Memoirs of the Societe Medicale d'Emulation, which he founded in 1796, and they were afterwards more fully See also:developed in his Traits sur See also:les membranes ("Soo). His next publication was the Recherches physiologiques sur la See also:vie et sur is molt (1800), and it was quickly followed by his Anatomie gentrale (1801), the work which contains the fruits of his-most profound and original researches. He began another work, under the See also:title Anatomie descriptive (1801–1803), in which the See also:organs were arranged according to his See also:peculiar See also:classification of their functions, but lived to publish only the first two volumes. It was completed on the same plan by his pupils, M. F.

R. See also:

Buisson (1776–1805) and P. J. Roux (1780–1854). Before Bichat had attained the See also:age of eight-and-twenty he was appointed physician to the Hotel Dieu, a situation which opened an immense See also:field to his ardent spirit of inquiry. In the investigation of diseases he pursued the same method of observation and experiment which had characterized his researches in physiology. He learned their See also:history by studying them at the bedside of his patients, and by accurate See also:dissection of their bodies after death. He engaged in a See also:series of See also:examinations, with a view to ascertain the changes induced in the various organs by disease, and in less than six months he had opened above six See also:hundred bodies. He was anxious also to determine with more precision than had been attempted before, the effects of remedial agents, and instituted with this view a series of See also:direct experiments which yielded a vast See also:store of valuable material. Towards the end of his See also:life he was also engaged on a new classification of diseases. A fall from a See also:staircase at the Hotel Dieu resulted in a See also:fever, and, exhausted by his excessive labours and by constantly breathing the tainted See also:air of the dissecting-See also:room, he died on the 22nd of See also:July 1802. His bust, together with that of Desault, was placed in the Hotel Dieu by See also:order of See also:Napoleon.
