ROST, Pierre Adolph, jurist, born in France about 1797" died in New Orleans, Louisiana, 6 September, 1868. He was educated at the Lycde Napoleon and the Ecole polytechnic in Paris. With his fellow-students he served in the defence of Paris when Napoleon retired to Elba, and on the restoration of the empire he applied for a commission, which would have been granted but for the defeat at Waterloo. In 1816 he came to Louisiana and settled at Natchez, Mississippi, and soon afterward he stud-led law with Joseph E. Davis. After his admission to the bar he settled in Natchitoches, where the population was largely French, and soon attained a profitable practice. In 1826 he was elected to the state senate, and four years later he was nominated for congressman, but was defeated. He then removed to New Orleans, and continued there in the practice of his profession until 1838, when he went to Europe. On his return he was appointed judge of the supreme court, but soon resigned to engage in agricultural pursuits. In 1846, when the reorganization of the court was effected, he again accepted a seat on the bench. On account of his ample knowledge of both civil and commercial law, he took rank among the foremost judges that Louisiana has ever possessed. It is said of him that "for dearness of diction and logical perspicacity in the application of legal principles to the facts of the ease in hand, his decisions will stand comparison with those rendered by the foremost jurists in the land." On the formation of the provisional Confederate government he was appointed its commissioner to Spain, and remained abroad until after the civil war. He then resumed his practice, and devoted his energies to the restoration of his property.
