NUCINGEN (Baron Frederic de), born, probably at Strasbourg, about 1767. At that place he was formerly clerk to M. d'Aldrigger, an Alsatian banker. Of better judgment than his employer, he did not believe in the success of the Emperor in 1815 and speculated very skilfully on the battle of Waterloo. Nucingen now carried on business alone, and on his own account, in Paris and elsewhere; he thus prepared by degrees the famous house of the rue Saint-Lazare, and laid the foundation of a fortune, which, under Louis Philippe, reached almost eighteen million francs. At this period he married one of the two daughters of a rich vermicelli-maker, Mademoiselle Delphine Goriot, by whom he had a daughter, Augusta, eventually the wife of Eugene de Rastignac. From the first years of the Restoration may be dated the real brilliancy of his career, the result of a combination with the Kellers, Ferdinand du Tillet, and Eugene de Rastignac in the successful manipulation of schemes in connection with the Wortschin mines, followed by opportune assignments and adroitly managed cases of bankruptcy. These various combinations ruined the Ragons, the Aiglemonts, the Aldriggers, and the Beaudenords.

After Esther's suicide, in May, 1830, Nuncingen abandoned "Cythera," as Chardin des Lupeaulx had done before, and became again a man of figures, and was overwhelmed with favors: insignia, the peerage, and the cross of grand officer of the Legion of Honor. Nucingen, being respected and esteemed, in spite of his blunt ways and his German accent, was a patron of Beaudenord, and a frequent guest of Cointet, the minister; he went everywhere, and, at the mansion of Mademoiselle des Touches, heard Marsay
