Chalotais, La, Louis Rene de taradenc de, a French statesman and author, born at Rennes, March 6, 1701, died there, July 12, 1785. He was procureur general of the parliament of Brittany, and became known by his reports to that body against the Jesuits, the authorship of which was ascribed to D'Alembert. A new edition of these Comptes rendus des constitutions des Jesuites (2 vols., Paris, 1761-2) was published in 1826. According to Grimm, his reports led to the abolition of the society of Jesus in France; and he as well as Voltaire also awarded the highest praise to La Chalo-tais's Essai d'education nationale (1763; new eds., Paris, 1825 and 1820). Having become engaged in a dispute with the duke d'Aiguillon, governor of Brittany, that functionary accused him of seditious proceedings, and had him arrested (Nov. 11, 1765), with four of his colleagues and his son Caradeuc de la Chalotais, who was also a procureur general in the Rennes parliament. He was detained in the castle of St. Malo, and wrote there, Jan. 15, 1766, with his toothpick in the absence of pens, his first memoir in vindication of his course. Voltaire averred that this toothpick had achieved immortality.
He wrote several similar memoirs, and the proceedings against him, being regarded as an infringement of the rights of parliament, gave rise to protracted controversies. The parliament eventually instituted proceedings against the duke d'Aiguillon, who was proved to have procured evidence against La Chalotais by false witnesses, and whose papers were seized and publicly burned by order of the parliament, though he brought countercharges against his adversaries, and the crown seemed to take up his case as against parliament. After much agitation the matter came before the parliament of Paris in 1770. Louis XV. at first presided, but soon' withdrew on the pretext that his royal authority was impaired by the pretensions of the parliament. This body, however, insisted on its prerogatives, and continued its investigations; but La Chalotais did not recover his liberty till 1775, after the king's death, when he resumed his previous position at the parliament of Rennes. Le proces de M. de la Chalotais was published in 1707 (3 vols. 4to).
