Franceis Xavier De Feller, a Belgian author, born in Brussels, Aug. 18, 1735, died in Ratis-bon, May 21, 1802. He was educated in the Jesuits' colleges at Luxemburg and Rheims, and after becoming a member of their order was employed as professor at Luxemburg and Liege. He went afterward to Tyrnau in Hungary, and after passing some time there, he travelled extensively in Hungary, Austria, Bohemia, Poland, and Italy. He was preacher in the college of Liege when the order of Jesuits was suppressed in Belgium in 1773, and afterward devoted himself to literature. Being compelled to leave Belgium at the occupation of that country by France in 1794, he spent two years at Paderborn, and subsequently retired to Ratisbon. Among his works are Observations philosophiquessur le systeme de New-ton (3d and enlarged ed., Liege, 1778), and Catechisme philosophique (4th ed., 1805; new ed., from the author's annotations, Lyons, 1819). He left many other writings, chiefly on religious subjects; but his principal work is his Biographie universelle, ou Dictionnaire his-toripue, etc, which passed through many editions, and after his death was revised and continued under the direction of M. Charles Weiss and the abbe Busson, and brought down to 1848 (9 vols. 8vo, Paris, 1847-56).
