Sébastien René Lenormand
Sébastien René Lenormand (2 April 1796, in Condé-sur-Noireau – 10 December 1871) was a French lawyer and botanist who specialized in the field of phycology. From 1817 he studied law in Paris, and following graduation (1820), practiced law in the town of Vire. In 1835 he quit the legal profession, moved to an estate called "Lénaudières", from where he focused his energies towards botany. As a botanist, he created an impressive herbarium, consisting mainly of algae species. Although he never left France, he collected a large number of botanical specimens from naturalists who travelled to all parts of the globe. The algae genus ''Lenormandia'' (family Rhodomelaceae) was named in his honor by Otto Wilhelm Sonder in 1845. Written works * ''Note sur l'emploi du sulfure de carbone pour la conservation des herbiers'' (1858) – On the usage of sulfur and carbon for preservation of herbaria. * ''Catalogue des plantes recueillies a Cayenne'' (1859, with Émile Deplanche) †...

Sulfur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Condé-sur-Noireau
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Émile Deplanche
Émile Deplanche (22 June 1824 in Argentan – 30 March 1874) was a French physician and naturalist. He studied medicine and zoology in Caen. In 1854 he served as a surgeon in the Crimean War, and later the same year, he travelled as a surgeon to Cayenne, Guyane. Here he distinguished himself as a physician, dealing with a yellow fever epidemic that had ravaged the colony (1855). While in Guyane, he collected numerous zoological and botanical specimens. After spending a period of recovery time in France, he embarked on a ship to Tahiti, where he collected malacological and ornithological specimens.JSTOR Global Plants biography.

Herbaria
A herbarium (plural: herbaria) is a collection of preserved plant specimens and associated data used for scientific study. The specimens may be whole plants or plant parts; these will usually be in dried form mounted on a sheet of paper (called '' exsiccatum'', plur. ''exsiccata'') but, depending upon the material, may also be stored in boxes or kept in alcohol or other preservative. The specimens in a herbarium are often used as reference material in describing plant taxa; some specimens may be types. The same term is often used in mycology to describe an equivalent collection of preserved fungi, otherwise known as a fungarium. A xylarium is a herbarium specialising in specimens of wood. The term hortorium (as in the Liberty Hyde Bailey Hortorium) has occasionally been applied to a herbarium specialising in preserving material of horticultural origin. History The making of herbaria is an ancient phenomenon, at least six centuries old, although the techniques have change ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
