Louis Joseph Antoine Dc Potter, a Belgian revolutionist, born in Bruges, April 26, 1786, died there, July 22,1859. He spent his youth partly in Holland, partly in Germany, and lived from 1809 to 1811 in southern France, and in Italy till about 1824, when he returned to Brussels. He was one of the bitterest opponents of the Dutch government, and in 1828 was sentenced to 18 months' imprisonment and a fine of 1,000 florins. The people bore him in triumph to his prison, and he there wrote a pamphlet on "The Union of the Catholics and the Liberals." For other publications he was sentenced in April, 1830, to eight years' banishment. After the French revolution of July he took up his residence in Paris, and addressed a letter to the king of the Netherlands, advising him to constitute Belgium a separate state. On the breaking out of the Belgian revolution in September he returned to Brussels, where he became a member of the provisional government, and urged the establish-lishment of a republic. After the dissolution of the provisional government he was obliged to flee to France, and took no further part in political affairs.

The most important of his numerous works is his Histoire philosophique du Ghristianisme (8 vols., Paris, 1836-7; abridged ed., 2 vols., 1856).
