	Nees Christian Gottfried Daniel Nees von Esenbeck (14 February 1776 – 16 March 1858) was a prolific German botanist, physician, zoologist, and natural philosopher. He was a contemporary of Goethe and was born within the lifetime of Linnaeus. He described approximately 7,000 plant species (almost as many as Linnaeus himself). His last official act as president of the German Academy of Natural Scientists Leopoldina was to admit Charles Darwin as a member. He was the author of numerous monographs on botany and zoology. His best-known works deal with fungi. Biography Nees von Esenbeck was born in Schloss Reichenberg near Reichelsheim (Odenwald). He showed an early interest in science and, after receiving his primary education in Darmstadt, he went on to the University of Jena, obtaining his degree in biology (natural history) and medicine in 1800. He practiced as a physician for Francis I (Erbach-Erbach), but he had developed a great interest in botany during his university studies, a ...

picture info	Celluloid Celluloids are a class of materials produced by mixing nitrocellulose and camphor, often with added dyes and other agents. Once much more common for its use as photographic film before the advent of safer methods, celluloid's common contemporary uses are table tennis balls, musical instruments, combs, office equipment, and guitar picks. History Nitrocellulose Nitrocellulose-based plastics slightly predate celluloid. Collodion, invented in 1848 and used as a wound dressing and an emulsion for photographic plates, is dried to a celluloid like film. Alexander Parkes The first celluloid as a bulk material for forming objects was made in 1855 in Birmingham, England, by Alexander Parkes, who was never able to see his invention reach full fruition, after his firm went bankrupt due to scale-up costs. Parkes patented his discovery as Parkesine in 1862 after realising a solid residue remained after evaporation of the solvent from photographic collodion. Parkes patented it as a clothi ...

picture info	Perfumer And Flavorist A perfumer is an expert on creating perfume compositions, sometimes referred to affectionately as a ''nose'' (French: ''nez'') due to their fine sense of smell and skill in producing olfactory compositions. The perfumer is effectively an artist who is trained in depth on the concepts of fragrance aesthetics and who is capable of conveying abstract concepts and moods with compositions. At the most rudimentary level, a perfumer must have a keen knowledge of a large variety of fragrance ingredients and their smells, and be able to distinguish each one alone or in combination with others. They must also know how each reveals itself over time. The job of the perfumer is very similar to that of flavourists, who compose smells and flavourants for commercial food products. Training Most past perfumers did not undergo professional training in the art, and many learned their craft as apprentices under another perfumer in their employment as technicians (in charge of blending formulas) or c ...
