Life
Joseph L. Proust was born on September 26, 1754 in Angers, France. His father served as an apothecary in Angers. Joseph studied chemistry in his father’s shop and later came to Paris where he gained the appointment of apothecary in chief to the Salpetriere . He also taught chemistry with Pilâtre de Rozier, a famous aeronaut.
Under Carlos IV's influence Proust went to Spain. There he taught at the Chemistry School in Segovia and at the University of Salamanca. But when Napoleon invaded Spain, they burned Proust's laboratory and forced him back to France. On July 5 1826 he died in Angers, France.The mineral proustite (Ag3AsS3) is named in his honour.
Proust's best known work was derived from a controversy with C.L. Berthollet. Berthollet did not believe that substances always combine in constant and definite proportions as Proust did. Proust eventually was able to prove Berthollet wrong in 1799 and published his own hypothesis.

Famous quotes containing the word life:
“Just so hollow and ineffectual, for the most part, is our ordinary conversation. Surface meets surface. When our life ceases to be inward and private, conversation degenerates into mere gossip.”
—Henry David Thoreau (1817–1862)
“The goal in raising one’s child is to enable him, first, to discover who he wants to be, and then to become a person who can be satisfied with himself and his way of life. Eventually he ought to be able to do in his life whatever seems important, desirable, and worthwhile to him to do; to develop relations with other people that are constructive, satisfying, mutually enriching; and to bear up well under the stresses and hardships he will unavoidably encounter during his life.”
—Bruno Bettelheim (20th century)
“All my life long I have been sensible of the injustice constantly done to women. Since I have had to fight the world single-handed, there has not been one day I have not smarted under the wrongs I have had to bear, because I was not only a woman, but a woman doing a man’s work, without any man, husband, son, brother or friend, to stand at my side, and to see some semblance of justice done me. I cannot forget, for injustice is a sixth sense, and rouses all the others.”
—Amelia E. Barr (1831–1919)
