occupied eleven years. His MS. inventory is preserved in the original and in copy in the Bibliothèque Nationale, and transcriptions are in the national archives in Paris, at the record office in London, and elsewhere. Dupuy’s classification is still regarded with respect, but the inventory has been partially replaced by the publication of the Layettes du trésor (four volumes, coming down to 1270; 1863–1902). Dupuy also published, with his brother Jacques, and their friend Nicolas Rigault, the History of Aug. de Thou (1620, 1626). The two brothers then bought from Rigault the post of keeper of the king’s library, and drew up a catalogue of the library (Nos. 9352-9354 and 10366-10367 of the Latin collection in the Bibliothèque Nationale). In the course of this work, Dupuy became acquainted with and copied an enormous mass of unpublished documents, which furnished him with the material for some excellent works: Traité des droits et des libertés de l’église gallicane, avec les preuves (1639), Histoire de l’ordre militaire des Templiers (1654), Histoire générale du schisme qui a été dans l’église depuis 1378 jusqu’à 1428 (1654), and Histoire du différend entre le pape Boniface VIII et le roi Philippe le Bel (1655). These works, especially the last, are important contributions to the history of the relations of church and state in the middle ages. They were written from the Gallican standpoint, i.e. in favour of the rights of the crown in temporal and political matters, and this explains the delay in their publication until after Dupuy’s death. He wrote also Traité des régences et des majorités des rois de France (1655) and Recueil des droits du roi (1658). Dupuy’s papers, preserved in the Bibliothèque Nationale, were inventoried by Léon Dorez (Catalogue de la collection Dupuy, 1899). See also L. Delisle’s Le Cabinet des manuscrits de la bibliothèque impériale. Dupuy died in Paris on the 14th of December 1651.
DUPUY DE LÔME, STANISLAS CHARLES HENRI LAURENT (1816–1885), French naval architect, the son of a retired naval officer, was born at Ploemeur, near Lorient, on the 15th of October 1816. He entered the École Polytechnique in 1835, and in 1842 was sent to England to study and report on iron shipbuilding. Acting on his report, which was published in 1844, the government built their first iron vessels under his supervision. He planned and built the steam line-of-battle ship “Napoleon” (1848–1852), and devised the method of altering sailing ships of the line into steamers, which was afterwards extensively practised in both France and England. He also showed the practicability of armouring the sides of a ship, and the frigate “Gloire” gave a very clear demonstration of his views. It was the beginning of the great change in the construction of ships of war which has been going on ever since. In 1857 Dupuy de Lôme was appointed “chef de la direction du matériel,” at Paris; and in 1861, “inspecteur général du matériel de la marine.” In 1866 he was elected a member of the Academy of Sciences. At the beginning of the Franco-German War he was appointed a member of the committee of defence, and during the siege of Paris occupied himself with planning a steerable balloon, for carrying out which he was given a credit of 40,000 fr.; but the balloon was not ready till a few days before the capitulation. The experiments that were afterwards made with it did not prove entirely satisfactory. In 1875 he was busy over a scheme for embarking a railway train at Calais, and exhibited plans of the improved harbour and models of the “bateaux porte-trains” to the Academy of Sciences in July. In 1877 he was elected a senator for life. He received the cross of the Legion of Honour in 1845, was made a commander in 1858, and grand officer in December 1863. He died at Paris on the 1st of February 1885.
DUPUYTREN, GUILLAUME, Baron (1777–1835), French anatomist and surgeon, was born on the 6th of October 1777 at Pierre Buffière (Haute Vienne). He studied medicine in Paris at the newly established École de Médecine, and was appointed by competition prosector when only eighteen years of age. His early studies were directed chiefly to morbid anatomy. In 1803 he was appointed assistant-surgeon at the Hôtel-Dieu, and in 1811 professor of operative surgery in succession to R. B. Sabatier (1732–1811). In 1815 he was appointed to the chair of clinical surgery, and became head surgeon at the Hôtel-Dieu. Dupuytren’s energy and industry were alike remarkable. He visited the Hôtel-Dieu morning and evening, performing at each time several operations, lectured to vast throngs of students, gave advice to his outdoor patients, and fulfilled the duties consequent upon one of the largest practices of modern times. By his indefatigable activity he amassed a fortune of £300,000, the bulk of which he bequeathed to his daughter, with the deduction of considerable sums for the endowment of the anatomical chair in the École de Médecine, and the establishment of a benevolent institution for distressed medical men. The most important of Dupuytren’s writings is his Treatise on Artificial Anus, in which he applied the principles laid down by John Hunter. In his operations he was remarkable for his skill and dexterity, and for his great readiness of resource. He died in Paris on the 8th of February 1835.
DUQUE DE ESTRADA, DIEGO (1589–?), Spanish memoir writer, soldier and adventurer, son of Juan Duque de Estrada, also a soldier of rank, was born at Toledo on the 15th of August 1589. Having been left an orphan when very young, he was educated by a cousin. While still young he was betrothed to his cousin’s daughter. One night he found an intruder in the house, a gentleman with whom he was acquainted, and in a fit of jealousy killed both him and the young lady. The prevailing code of honour was considered a sufficient justification for Duque de Estrada’s violence, but the law looked upon the act as a vulgar assassination, and he had to flee. After leading a vagabond life in the south of Spain, he was arrested at Ecija, was brought to Toledo, and was there put to the torture with extreme ferocity, in order to extort a general confession as to his life during the past months. He had the strength not to yield to pain, and was finally able to escape from prison, partly by the help of a nun in a religious house which faced the prison, and partly by the intervention of friends. He made his way to Naples, where he entered the service of the duke of Osuna (q.v.), at that time viceroy. Duque de Estrada saw a good deal of fighting both with the Turks and the Venetians; but he is mainly interesting because he was employed by the viceroy in the conspiracy against Venice. He was one of the disguised Spanish soldiers who were sent into the town to destroy the arsenal, and who were warned in time that the conspiracy had been betrayed, and therefore escaped. After the fall of his patron, Duque de Estrada resumed his vagabond life, served under Bethlen Gabor in Transylvania, and in the Thirty Years’ War. In 1633 he entered the order of San Juan de Dios, and died at some time after 1637 in Sardinia, where he is known to have taken part in the defence of the island against an attack by the French. He left a book of memoirs, entitled Comentarios de el desengañado de si Mismo prueba de todos estados, y eleccion del Mejor de ellos—“The Commentaries of one who knew his own little worth, the touchtstone of all the state of man, and the choice of the best.” They were written at different times, and part has been lost. The style is incorrect, and it would be unsafe to trust them in every detail, but they are amazingly vivid, and contain a wonderful picture of the moral and intellectual state of a large part of Spanish society at the time.
The memoirs have been reprinted by Don Pascual de Gayangos in the Memorial histórico español, vol. xii. (Madrid, 1860).
DUQUESNE, ABRAHAM, Marquis (1610–1688), French naval officer, was born at Dieppe in 1610. Born in a stirring seaport, the son of a distinguished naval officer, he naturally adopted the profession of a sailor. He spent his youth in the merchant service, and obtained his first distinction in naval warfare by the capture of the island of Lerins from the Spaniards in May 1637. About the same time his father was killed in an engagement with the Spaniards, and the news raised his hatred of the national enemy to the pitch of a personal and bitter animosity. For the next five years he sought every opportunity of inflicting defeat and humiliation on the Spanish navy, and he distinguished himself by his bravery in the engagement at Guetaria (1638), the expedition to Corunna (1639), and in battles at Tarragona (1641), Barcelona (1643), and the Cabo de Gata.
