Charles Jeunet Duval

from Wikipedia, the free encyclopedia

Charles François Jeunet Duval (born January 10, 1751 in Roye , † September 15, 1828 at Irlbach Castle ) was a French botanist .

Life

Duval was the son of a French officer and also pursued a military career himself. After killing an opponent in a duel, he had to flee France. From 1788 he was initially a fencing and language teacher at the court of Prince Thurn and Taxis in Regensburg , later professor of mathematics and natural history at the princely pagerie. In 1789 he became the German teacher of Count François Gabriel de Bray , who had also fled France. In 1806 he retired. From 1813 he lived with his friend and patron de Bray at Irlbach Castle near Straubing.

De Bray aroused Duval's interest in botany. In May 1790 he was alongside David Heinrich Hoppe and other founding members and from 1811 to 1832 President of the Regensburg Botanical Society. In his scientific work he dealt with flowering plants and cryptgams. He particularly researched the flora of the region around Regensburg. He published his results in the botanical pocket book for beginners of this science and the pharmacist's art, edited by Hoppe . His herbarium became the property of the Regensburg Botanical Society in 1836. In recognition of his research, Johann Gottlieb Wilhelm Voit named the moss species Bryum duvalii after him .

Duval died in Irlbach Castle in 1828 and was buried in the cemetery there. Count de Bray had an obelisk erected in his honor in the palace gardens.
