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:

    Italy is such a delightful place to live in if you happen to be a man. There one may enjoy that exquisite luxury of Socialism—that true Socialism which is based not on equality of income or character, but on the equality of manners. In the democracy of the caffè or the street the great question of our life has been solved, and the brotherhood of man is a reality. But it is accomplished at the expense of the sisterhood of women.
    —E.M. (Edward Morgan)

    No civilization ... would ever have been possible without a framework of stability, to provide the wherein for the flux of change. Foremost among the stabilizing factors, more enduring than customs, manners and traditions, are the legal systems that regulate our life in the world and our daily affairs with each other.
    Hannah Arendt (1906–1975)

    Seeing to it that a youngster grows up believing not just in the here and now but also in the grand maybes of life guarantees that some small yet crucial part of him remains forever a child.
    Anne Cassidy (20th century)
