Honours Joy Désor (b. 1990), for his tireless analytical work on mineral unknowns, which has led to the discovery and description of the new minerals ammoniotinsleyite, bojarite, oberwolfachite, oldsite, theuerdankite and hanauerite. Joy did the initial work that suggested that the new mineral described herein could be new. At Joy’s suggestion, the name désorite also honours his noteworthy ancestor Pierre Jean Édouard Désor (13 February 1811, Friedrichsdorf, Grand Duchy of Hesse – 23 February 1882 Nice), a Swiss geologist and professor at Neuchâtel Academy (now the University of Neuchâtel). He was a colleague of Louis Agassiz, among others. His studies on paleontology and glacial phenomena in Europe and North America are of particular note. He was a collaborator on the geological survey of the Lake Superior mineral district in the USA.
