physiocrats, but was really written before the marquis had made the acquaintance of the physician of Madame de Pompadour. In 1760 he published his Théorie de l'impot, in which he attacked with all the vehemence of his son the farmers-general of the taxes, who got him imprisoned for eight days at Vincennes, and then exiled to his country estate at Bignon near Nemours. At Bignon the school of the physiocrats was really established, and the marquis in 1765 bought the Journal de l'agriculture, du commerce, et des finances, which became the organ of the school. He was recognized as a leader of political thinkers by Prince Leopold of Tuscany, afterwards emperor, and by Gustav III of Sweden, who in 1772 sent him the Grand Cross of the Order of Vasa. But his marriage had not been happy; he had separated from his wife in 1762, and had, he believed, secured her safely in the provinces by a lettre de cachet, when in 1772 she suddenly appeared in Paris, and commenced proceedings for a separation. One of his own daughters had encouraged his wife to take this step. He was determined to keep the case quiet, if possible, for the sake of Mme de Pailly, a Swiss lady whom he had loved since 1756. But his wife would not let him rest; her plea was rejected in 1777, but she renewed her suit, and, though Honoré had pleaded his father's case, was successful in 1781. This trial quite broke the health of the marquis, as well as his fortune; he sold his estate at Bignon, and hired a house at Argenteuil, where he lived quietly till his death. The marquis's younger brother, Jean Antoine Riquetti, the bailli (d. 1794), served with distinction in the navy, but his brusque manners made success at court impossible. In 1763 he became general of the galleys of Malta. In 1767 he returned to France and took charge of the château de Mirabeau, helping the marquis in his disastrous lawsuits. Mirabeau was nicknamed "Friend of Man", after his work L'Ami des Hommes.
