PROUDHON, PIERRE JOSEPH, a French publicist; born in Besangon, France, July 15, 1809. He was em- ployed in various printing offices till 1837, but had found time to think and study.

After the revolu- tion of February, 1848, Proudhon was editor of *'The People's Representa- tive," and attracted great attention and popularity, and was chosen member of the Constituent Assembly. But he found no hearing, and therefore started a newspaper under the title of "The Peo- ple," which was suppressed. In 1849, he founded his People's Bank, but being soon after sentenced, under the press laws, to three years' imprisonment and a fine, he left France, and the bank was closed by the government.
