KATT, a Flemish woman, the nurse of Lydie de la Peyrade, whom she attended constantly in Paris on rue des Moineaux about 1829, and during her mistress' period of insanity on Rue Honore Chevalier in 1840. [Scenes from a Courtesan's Life. The Middle Classes.] KELLER (Francois), one of the influential and wealthy Parisian bankers, during a period extending perhaps from 1809 to 1839. As such, in November, 1809, under the Empire, he was one of the guests at a fine reception, given by Comte Malin de Gondreville, meeting there Isemberg, Montcornet, Mesdames de Lansac and de Vandemont, and a mixed company composed of members of the aristocracy and people illustrious under the Empire. At this time, moreover, Francois Keller was in the family of Malin de Gondreville, one of whose daughters he had married. This marriage, besides making him the brother-in-law of the Marechal de Carigliano, gave him assurance of the deputyship, which he obtained in 1816 and held until 1836. The district electors of Arcis-sur-Aube kept him in the legislature during that long period. Francois Keller had, by his marriage with Mademoiselle de Gondreville, one son, Charles, who died before his parents in the spring of 1839. As deputy, Francois Keller became one of the most noted orators of the Left Centre. He shone as a member of the opposition, especially from 1819 to 1825. Adroitly he drew about himself the robe of philanthropy. Politics never turned his attention from finance. Francois Keller, seconded by his brother and partner, Adolphe Keller, refused to aid the needy perfumer, Cesar Birotteau. Between 1821 and 1823 the creditors of Guillaume Grandet, the bankrupt, unanimously selected him and M. des Grassins of Saumur as adjusters. Despite his display of Puritanical virtues, the private career of Francois Keller was not spotless. In 1825 it was known that he had an illegitimate and costly liaison with Flavie Colleville. Rallying to the support of the new monarchy from 1830 to 1836, Francois Keller saw his Philippist zeal rewarded in 1839. He exchanged his commission at the Palais-Bourbon for a peerage, and received the title of count. [Domestic Peace. Cesar Birotteau. Eugenie Grandet. The Government Clerks.
