Joseph Proust - Life

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:

    The hardest part about being a kid is knowing you have got your whole life ahead of you.
    Jane Wagner (b. 1935)

    . . . you may think I waste my breath
    Pretending that there can be passion
    That has more life in it than death,
    William Butler Yeats (1865–1939)

    To suppose such a thing possible as a society, in which men, who are able and willing to work, cannot support their families, and ought, with a great part of the women, to be compelled to lead a life of celibacy, for fear of having children to be starved; to suppose such a thing possible is monstrous.
    William Cobbett (1762–1835)
