HASSELT, ANDRE HENRI CONSTANT VAN (1806-1874), Belgian poet, was born at Maastricht, in Limburg, on Jan. 5, 1806. He was educated in his native town, and at the University of Liege. In 1833 he left Maastricht, then blockaded by the Belgian forces, and made his way to Brussels, where he became a naturalized Belgian, and was attached to the Biblio theque de Bourgogne. In 1843 he entered the education depart ment, and eventually became an inspector of normal schools. His native language was Dutch, and as a French poet Andre van Hasselt had to overcome the difficulties of writing in a foreign language. His first volume of verse, Primeveres (1834), shows markedly the influence of Victor Hugo, which had been strength ened by a visit to Paris in 1830. His relations with Hugo became intimate in 1851-52, when the poet was an exile in Brussels. His chief work, the epic of the Quatre Incarnations du Christ, was published in 1867. In the same volume were printed his Etudes rythmiques, a series of metrical experiments designed to show that the French language could be adapted to every kind of musical rhythm. He died in Dec. A selection from his works (10 vols., 1876-77) was edited by Charles Hen and Louis Alvin. He wrote many books for children, chiefly under the pseudonym of Alfred Avelines; and studies on historical and lit erary subjects. The books written in collaboration with Charles Hen are signed Charles Andre. A bibliography of his writings is appended to the notice by Louis Alvin in the Biographie nat. de Belgique, vol. vii. A series of tributes to his memory are printed in the Poesies choisies 0900, edited by Georges Barral for the Collection des poetes f rancais de l'etranger. This book contains a biographical and critical study by Jules Guillaume, and some valuable notes on the poet's theories of rhythm.
