Jules Gosselet

Jules-Auguste Gosselet (19 April 1832 – 20 March 1916) was a French geologist born in Cambrai, France.

Following unsuccessful studies of pharmacy, and a stint as a mathematics teacher at the Lycée du Quesnoy, he pursued a career in natural history. In 1853 he became a preparateur of geology at the Sorbonne, later obtaining his doctorate with a thesis titled Mémoire sur les terrains primaires de la Belgique, des environs d'Avesnes et du Boulonnais (1860). Other significant writings include a geological treatise on the Ardennes, L'Ardenne (1888), and hydrogeological research on the aquifers of Nord, Leçons sur les nappes aquifères du Nord (1887). Also, he is credited with providing a thorough description of the geological beds in the limestone at Étrœungt (schistes et calcaire d’Etroeungt).

In the field of paleontology, he performed pioneer "zoometric" research of a species of brachiopod known as Spirifer verneuilli (Etudes sur les variations du Spirifer Verneuilli).

Since 1910, the Prix Gosselet is awarded every four years for accomplishments made in the field of applied geology. The mineral gosseletite, a phase of manganian andalusite, is named after him.
