Barrot. I. Camille Hyacinthe Odilon, popularly known as Odilon Barrot, a French advocate and statesman, born at Villefort, department of Lozere, in July, 1791. His father was a revolutionist, but Odilon became after his admission to the bar in 1814 friendly to Louis XVIII.; but subsequently he was prominent in the opposition, and acquired great celebrity as an advocate, especially in political trials. He contributed as president of one of the principal political associations, and by his activity, to bring on the revolution of 1830, and was secretary of the Paris municipal committee which in July officiated for a few days as a provisional government. He opposed the establishment of a republic as well as the restoration of the elder Bourbons, and contributed much to make Louis Philippe king, but showed personal deference to the deposed monarch, escorting him and his family to Cherbourg. Louis Philippe appointed him prefect of the department of the Seine, but was not able to sustain him against the subsequent attacks of Guizot and his party, who especially censured his attitude during the trial of Polignac. The disorders following the funeral celebration by legitimists of the anniversary of the assassination of the duke de Berri, on which occasion he was accused of negligence, furnished a pretext for his removal, and on Feb. 19, 1831, he resigned the prefecture.

He now became a leader of the moderate left in the chamber of deputies, opposing a hereditary peerage, promoting the revision of the penal code and public instruction, and obtaining the repeated adoption of a divorce bill in the chamber, notwithstanding its rejection by the peers. He bore an important part in all the political events which preceded the revolution of 1848, as one of the most eloquent orators and influential statesmen of his day, and was the chief promoter of the famous reform banquets. He submitted to the chamber the act of accusation against the Guizot ministry, signed by 53 of his colleagues, and was appointed by Louis Philippe prime minister on Feb. 24. In this capacity it was his duty to announce the king's abdication and the accession of the duchess of Orleans as regent. He had flattered himself that his influence would allay the revolutionary storm; but he was disappointed, and the republic was proclaimed. He became a member of the constituent assembly, and labored in vain for the adoption of a constitution after the English model.

Under the presidency of Louis Napoleon he was appointed minister of justice, with the privilege of presiding over the cabinet in the absence of the prince, Dec. 20, 1848. On April 16, 1849, he assumed the responsibility for the siege of Rome, but retired at the end of October on account of ill health. Subsequently failing to effect a reconciliation between the executive and the legislature, he was among the first to protest against the coup d'etat of Dec. 2, 1851, and to join in the unavailing proclamation deposing Louis Napoleon. In 1863 he endeavored in vain to be elected to the chamber, and at the close of 1869 he declined to accept the ministry of justice, which was tendered to him by Napoleon III. In 1872 M. Thiers appointed him vice president of the council of state. II. Victorin Ferdinand, brother of the preceding, born in Paris, Jan. 10, 1806. He became a member of the chamber of deputies and solicitor of the treasury, and in 1848 he was elected to the constituent assembly for Algeria, and in the following year to the legislative assembly.

Having been one of the counsel for Louis Napoleon in his trial for the attempt of Boulogne, he became on the accession of the latter to the presidency secretary general of his cabinet, and for a few months minister of the interior, after which he went in 1850 as minister to Turin, and was reelected to the legislative assembly. In January, 1852, he became a member of the consultative committee, and subsequently of the council of state in connection with public works, commerce, and agriculture. In 1853 he was made senator, and in 1865 secretary of the senate.
