Valentin Jameray Duval, a French scholar, born in Champagne in 1695, died in Vienna in September, 1775. He was of humble parentage, and was employed in his boyhood as a herdsman, but found time for study. He accumulated about 200 books and a few maps, and one day was found in the midst of them by Leopold of Lorraine, who placed him under the instruction of the Jesuits of Pont-a-Mousson. Here he made rapid progress, and Duke Leopold took him to Paris in 1718, subsequently appointing him librarian and professor of history at the noblemen's academy of Luneville. When Duke Francis Stephen, ceding Lorraine, became grand duke of Tuscany, he accompanied him as librarian to Florence. Here he resided for nearly ten years, until called to preside over the collection of coins and medals at Vienna, Francis Stephen having married Maria Theresa and become emperor of Germany. His complete works, chiefly on numismatics, with a memoir, were published at Basel (with the imprint of St. Petersburg) in 1784, in 2 vols. 8vo, and at Paris in 1785, in 3 vols. 18mo.
