Henri (or Henry) Calixte Miot (1841-1938) was linked by his family ties to the Diderot family, and hence to the famous encyclopedist Diderot. He was born on 3 June 1841 in Langres (France, Haute-Marne) in a family of lawyers. His major commitment in his career was about justice, and also the protection of animals. In particular he wrote a little book on the legal implementation of animal protection (domestic animals mistreated) (Miot, 1870b). Member of the Société protectrice des Animaux, he was convinced (just as Duméril) that the birds, the reptiles and the insects were useful to regulate the populations of the insect pests, and that we need to protect them (Miot, 1870a).
Settled in the surroundings of Dijon, he was in the magistracy as substitute for the Imperial Prosecutor in Semur-en-Auxois (France, Côte-d’Or), and later as investigating judge in Beaune. He was also a great collector. We know in particular that he was interested in philately  and in bibliophily. In natural sciences, he was interested in entomology, geology and malacology. His collection is housed in the geological collections of the University of Burgundy (UBG).
It consists of seven drawers exclusively dedicated to Unionid shells, with some Cyclas and Corbicula species (233 lots). The material originates from North America (United States and Canada), Africa and Middle-East (Gabon, Algeria, Egypt, Iraq) and Europa (Spain, France and Italy). The majority of the specimens is from France, and their provenance shows they originate from the Drouët collection. Henri Drouët (1829-1900) was an administrator and a famous conchologist specialized in the Unionidae family, living in Troyes before moving to Dijon. The two persons were in close connection but probably only at the end of Drouët’s life. He mentioned him for the first time in 1898 in Unionidés du Bassin de la Seine, and probably he did not have time to give him an eponym. Besides Drouët, some other collectors appears in the provenance data of his collection, such as Léon Provancher (1820-1892) and Mr. Pétot.
