Louis Joseph D'Albert D'Ailly
Louis Joseph d'Albert d'Ailly (1741–1792), seventh Duke of Chaulnes and son of Michel Ferdinand d'Albert d'Ailly, was a chemist and French aristocrat. Biography At the death of his father in 1769, Louis Joseph inherited the title of Duke of Picquigny. He studied science successfully and in 1764 was elected a Fellow of the Royal Society in London. He retired from military service at the age of twenty-four with the simple rank of colonel and instead undertook the study of natural sciences. In 1775, he proved that the poisonous air produced in the brewing process was carbon dioxide, and demonstrated a method of easily preparing acidic water with instruments with which water was shaken above vats where beer was fermenting. He showed a method of extracting and purifying salts from urine. In 1773, he found a way to crystallize alkalis by saturating carbon dioxide over a vat of beer. Chemists at the time recognised that asphyxiation from coal fumes is due to the formation of carbon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Valet
A valet or varlet is a male servant who serves as personal attendant to his employer. In the Middle Ages and Ancien Régime, valet de chambre was a role for junior courtiers and specialists such as artists in a royal court, but the term "valet" by itself most often refers to a normal servant responsible for the clothes and personal belongings of an employer, and making minor arrangements. In the United States, the term most often refers to a parking valet, and the role is often confused with a butler. Word origins In English, ''valet'' as "personal man-servant" is recorded since 1567, though use of the term in the French-speaking English medieval court is older, and the variant form ''varlet'' is cited from 1456 (OED). Both are French importations of ''valet'' or ''varlet'' (the "t" being silent in modern French), Old French variants of ''vaslet'' "man's servant", originally "squire, young man", assumed to be from Gallo-Romance Vulgar Latin *''vassellittus'' "young nobleman ...

18th-century French Chemists
The 18th century lasted from January 1, 1701 ( MDCCI) to December 31, 1800 ( MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the American, French, and Haitian Revolutions. During the century, slave trading and human trafficking expanded across the shores of the Atlantic, while declining in Russia, China, and Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in human society and the environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolution, with an emphasis on directly interconnected events.

Year 179 ( CLXXIX) was a common year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Veru (or, less frequently, year 932 ''Ab urbe condita''). The denomination 179 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Château De Vincennes
The Château de Vincennes () is a former fortress and royal residence next to the town of Vincennes, on the eastern edge of Paris, alongside the Bois de Vincennes. It was largely built between 1361 and 1369, and was a preferred residence, after the Palais de la Cité, of French Kings in the 14th to 16th century. It is particularly known for its "donjon" or keep, a fortified central tower, the tallest in Europe, built in the 14th century, and for the chapel, Sainte-Chapelle de Vincennes, begun in 1379 but not completed until 1552, which is an exceptional example of Flamboyant Gothic architecture. Because of its fortifications, the château was often used as a royal sanctuary in times of trouble, and later as a prison and military headquarters. The chapel was listed as an historic monument in 1853, and the keep was listed in 1913. Most of the building is now open to the public.

Beaumarchais
Pierre-Augustin Caron de Beaumarchais (; 24 January 1732 – 18 May 1799) was a French polymath. At various times in his life, he was a watchmaker, inventor, playwright, musician, diplomat, spy, publisher, horticulturist, arms dealer, satirist, financier and revolutionary (both French and American). Born a Parisian watchmaker's son, Beaumarchais rose in French society and became influential in the court of Louis XV as an inventor and music teacher. He made a number of important business and social contacts, played various roles as a diplomat and spy, and had earned a considerable fortune before a series of costly court battles jeopardized his reputation. An early French supporter of American independence, Beaumarchais lobbied the French government on behalf of the American rebels during the American War of Independence. Beaumarchais oversaw covert aid from the French and Spanish governments to supply arms and financial assistance to the rebels in the years before France's forma ...

Academy Of Sciences
An academy of sciences is a type of learned society or academy (as special scientific institution) dedicated to sciences that may or may not be state funded. Some state funded academies are tuned into national or royal (in case of the United Kingdom i.e. Royal Society of London for Improving Natural Knowledge) as a form of honor. The other type of academies are '' Academy of Arts'' or combination of both (e.g., American Academy of Arts and Sciences). ''Academy of Letters'' is another related expression, encompassing literature. In non-English-speaking countries, the range of academic fields of the members of a national Academy of Science often includes scholarly disciplines which would not normally be classed as "science" in English. Many languages use a broad term for systematized learning which includes both natural sciences and social sciences and fields such as literary studies, linguistics, history, or art history. (Often these terms are calques from Latin ''scientia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hieroglyphs
A hieroglyph (Greek for "sacred carvings") was a character of the ancient Egyptian writing system. Logographic scripts that are pictographic in form in a way reminiscent of ancient Egyptian are also sometimes called "hieroglyphs". In Neoplatonism, especially during the Renaissance, a "hieroglyph" was an artistic representation of an esoteric idea, which Neoplatonists believed actual Egyptian hieroglyphs to be. The word ''hieroglyphics'' refers to a hieroglyphic script. The Egyptians invented the pictorial script, which refers to any writing system that employs images as symbols for various semantic entities, rather than the abstract signs used by alphabets. The appearance of these distinctive figures in 3000 BCE marked the beginning of Egyptian civilization. Though based on images, Egyptian script was more than a sophisticated form of picture-writing. Each picture/ glyph served one of three functions: (1) to represent the image of a thing or action, (2) to stand for a sound or ...

Ammonia
Ammonia is an inorganic compound of nitrogen and hydrogen with the formula . A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell. Biologically, it is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to 45% of the world's food and fertilizers. Around 70% of ammonia is used to make fertilisers in various forms and composition, such as urea and Diammonium phosphate. Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water. Although common in nature—both terrestrially and in the outer planets of the Solar System—and in wide use, ammonia is both caust ...
