Georges Henri Joseph Édouard Lemaître was a Belgian Catholic priest, theoretical physicist, and mathematician who made major contributions to cosmology and astrophysics. He was the first to argue that the recession of galaxies is evidence of an expanding universe and to connect the observational Hubble–Lemaître law with the solution to the Einstein field equations in the general theory of relativity for a homogenous and isotropic universe. That work led Lemaître to propose what he called the "hypothesis of the primeval atom", now regarded as the first formulation of the Big Bang theory of the origin of the universe.
Lettrism is a French avant-garde movement, established in Paris in the mid-1940s by Romanian immigrant Isidore Isou. In a body of work totaling hundreds of volumes, Isou and the Lettrists have applied their theories to all areas of art and culture, most notably in poetry, film, painting and political theory. The movement has its theoretical roots in Dada and Surrealism. Isou viewed his fellow countryman Tristan Tzara as the greatest creator and rightful leader of the Dada movement, and dismissed most of the others as plagiarists and falsifiers. Among the Surrealists, André Breton was a significant influence, but Isou was dissatisfied by what he saw as the stagnation and theoretical bankruptcy of the movement as it stood in the 1940s.
The Decapoda or decapods are an order of crustaceans within the class Malacostraca, and includes crabs, lobsters, crayfish, shrimp, and prawns. Most decapods are scavengers. The order is estimated to contain nearly 15,000 extant species in around 2,700 genera, with around 3,300 fossil species. Nearly half of these species are crabs, with the shrimp and Anomura including hermit crabs, porcelain crabs, squat lobsters making up the bulk of the remainder. The earliest fossils of the group date to the Devonian.
The Paguridae are a family of hermit crabs of the order Decapoda. The king crabs, Lithodidae, are now widely understood to be derived from deep within the Paguridae, with some authors placing their ancestors within the genus Pagurus.
Pagurus is a genus of hermit crabs in the family Paguridae. Like other hermit crabs, their abdomen is not calcified and they use snail shells as protection. These marine decapod crustaceans are omnivorous, but mostly prey on small animals and scavenge carrion. Trigonocheirus and Pagurixus used to be considered subgenera of Pagurus, but the former is nowadays included in Orthopagurus, while the latter has been separated as a distinct genus.
Axiidae is a family of crustaceans belonging to the infraorder Axiidea, within the order Decapoda.

The Parapaguridae are a family of marine hermit crabs from deep waters. Instead of carrying empty gastropod shells like other hermit crabs, they carry colonies of dozen or more sea anemones or zoanthids. Some genera, such as Bivalvopagurus and Tylaspis, do not inhabit shells. The following genera are included:
Munida is the largest genus of squat lobsters in the family Munididae, with over 240 species.
Eumunida is a genus of squat lobsters. The majority of its species are from the Pacific Ocean and are as follows:
Porcellanopagurus edwardsi is a species of hermit crab that lives in the waters around New Zealand and its subantarctic islands.
Porcellanopagurus is a genus of hermit crabs. The genus occurs in the Pacific and Indian Oceans.
Neoglyphea inopinata is a species of glypheoid lobster, a group thought long extinct before Neoglyphea was discovered. It is a lobster-like animal, up to around 15 centimetres (5.9 in) in length, although without claws. It is only known from 17 specimens, caught at two sites – one at the entrance to Manila Bay in the Philippines, and one in the Timor Sea, north of Australia. Due to the small number of specimens available, little is known about the species, but it appears to live up to five years, with a short larval phase. A second species, previously included in Neoglyphea, is now placed in a separate genus, Laurentaeglyphea.
Nicothoe tumulosa is a species of copepod parasitic on the gills of the glypheoid lobster Neoglyphea inopinata. It was described as a new species in 1976 by Roger F. Cressey. It can be differentiated from related species by the setal formula, and the trunk's covering of small bumps, which give the species its name.
Michèle de Saint Laurent was a French carcinologist. She spent most of her career at the Muséum national d'histoire naturelle in Paris, working on the systematics of decapod crustaceans; her major contributions were to hermit crabs and Thalassinidea, and she also co-described Neoglyphea, a living fossil discovered in 1975.
Jacques Forest was a French carcinologist.
Oncopagurus, is a genus of marine hermit crabs in the family Parapaguridae, which contains 25 species. Members of this genus live from 40 to 2,308 meters below the surface.
Paragiopagurus is a genus of hermit crabs in the family Parapaguridae, that contains 25 species. Members of this genus live at depths from 116 to 2,067 meters.
Armand Félix Marie Jobbé-Duval was a French painter and politician of Breton origin. He became known for his severely classical compositions, which included the ceiling decorations of many churches and public buildings. He was a committed Republican and secularist, and participated in the French revolutions of 1848 and 1870–71.
