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:
“He was discontented and wasted his life into the bargain; and yet he rated it as a gain in coming to America, that here you could get tea, and coffee, and meat every day. But the only true America is that country where you are at liberty to pursue such a mode of life as may enable you to do without these, and where the state does not endeavor to compel you to sustain slavery and war and other superfluous expenses which directly or indirectly result from the use of such things.”
—Henry David Thoreau (1817–1862)
“We are conscious of an animal in us, which awakens in proportion as our higher nature slumbers. It is reptile and sensual, and perhaps cannot be wholly expelled; like the worms which, even in life and health, occupy our bodies. Possibly we may withdraw from it, but never change its nature. I fear that it may enjoy a certain health of its own; that we may be well, yet not pure.”
—Henry David Thoreau (1817–1862)
“Remember the rights of the savage, as we call him. Remember that the happiness of his humble home, remember that the sanctity of life in the hill villages of Afghanistan, among the winter snows, is as inviolable in the eye of Almighty God, as can be your own.”
—W.E. (William Ewart)
