HALPERSOHN (Moses), a refugee Polish Jew, excellent physician, communist, very eccentric, avaricious, friend of Lelewel the insurrectionist. Time of Louis Philippe at Paris, he attended Vanda de Mergi, given up by several doctors, and also diagnosed her complicated disease. [The Seamy Side of History.] HALPERTIUS, assumed name of Jacques Collin. HANNEQUIN (Leopold), Parisian notary. The "Revue de l'Est," a paper published at Besancon, time of Louis Philippe, gave, in an autobiographical novel of its editor-in-chief, Albert Savarus, entitled "L'Ambitieux par Amour," the story of the boyhood of Leopold Hannequin, the author's inseparable friend. Savarus told of their joint travels, and of the quiet preparation made by his friend for a notaryship during the time known as the Restoration. During the monarchy of the barricades Hannequin remained the steadfast friend of Savarus, being one of the first to find his hiding-place. At that time the notary had an office in Paris. He married there to advantage, became head of a family, and deputy-mayor of a precinct, and obtained the decoration for a wound received at the cloister of Saint-Merri. He was welcomed and made use of in the Faubourg Saint-Germain, the Saint- Georges quarter and the Marais. At the Grandlieus' request he drew up the marriage settlement of their daughter Sabine with Calyste du Guenic--1837. Four years later he consulted with old Marshal Hulot, on rue du Montparnasse, regarding his will in behalf of Mlle. Fischer and Mme. Steinbock. About 1845, at the request of Heloise Brisetout, he drew up Sylvain Pons' will. [Albert Savarus. Beatrix. Cousin Betty.

[The Quest of the Absolute.] HAUDRY, doctor at Paris during the first part of the nineteenth century. An old man and an upholder of old treatments; having a practice mainly among the middle class.
