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:
“It is impossible, as impossible as to raise the dead, to restore anything that has ever been great or beautiful in architecture. That which I have ... insisted upon as the life of the whole, that spirit which is given only by the hand and eye of the workman, can never be recalled.”
—John Ruskin (1819–1900)
“I devoutly believe it is the writer who has matured the film medium more than anyone else in Hollywood. Even when he knew nothing about his work, he brought at least knowledge of life and a more grown-up mind, a maturer feeling about the human being.”
—Dudley Nichols (1895–1960)
“The child begins life as a pleasure-seeking animal; his infantile personality is organized around his own appetites and his own body. In the course of his rearing the goal of exclusive pleasure seeking must be modified drastically, the fundamental urges must be subject to the dictates of conscience and society, urges must be capable of postponement and in some instances of renunciation completely.”
—Selma H. Fraiberg (20th century)
