My partner is Haiquan Zheng. We are working on Alexandre Brongniart.

Article additions for Alexandre Brongniart
In 1797, he became a professor of natural history at the Central School of the Four Nations, and became the professor of minerology in 1822 at the Museum of Natural History in Paris. He was appointed in 1800 by Napoleon's minister of the interior Lucien Bonaparte director of the revitalized porcelain manufactory at Sèvres, holding this role until death. The young man took to the position a combination of his training as a scientist— especially as a mining engineer relevant to the chemistry of ceramics— his managerial talents and financial acumen and his cultivated understanding of neoclassical esthetic.[1] He remained in charge of Sèvres, through regime changes, for 47 years.

Work

In 1800, Brongniart published "Essai d’une classification naturelle des reptiles" which he compared the anatomy of reptiles in order to classify them into different groups. The four classifications were chelonians, saurians, ophidians, and batrachians. Batrachians is the only group that is no longer recognized as reptiles as they are amphibians. Brongniart worked with Cuvier to determine how old fossils were. Their paper “Essai sur la geographie mineralogique des environs de Paris” identified nine formations that had been formed over a very long period of time. The formations, starting with the oldest, were called the Chalk, Argile Plastique, Calcaire grossier, Calcaire silicieux, Formation gypseuse, Sabels et Gres marins, Gres sans coquilliers, Terrain d’eau douce, and Limon d’aterrissement. Brongniart found that some of the strata had marine mollusk fossils, and some had fresh water mollusk fossils. He used the alternation of these marine and fresh water layers to disproved the theory that strata was deposited by a shrinking ocean. Another significant thing Brongniart did in stratigraphy was using the fossil content in the strata he examined in Paris to identify strata in other locations instead of depth or lithology, as rocks can’t be expected to have the exact same characteristics or depth if deposited under different conditions. Brongniart published the first full length study of trilobites in which he classified a variety from Europe and North America and tried to group them based on age. This work contributed to later work on Paleozoic stratigraphy. Erm7vc (talk) 02:13, 21 March 2020 (UTC)

Family

His wife was Cecile Coquebert de Montbret (1782–1862), the daughter of the French consul to England, Charles-Etienne Coquebert de Montbret. They had three children together. Their son, Adolphe-Théodore Brongniart, became a major figure in the study of paleobotany. Their daughter Hermine (1803–1890) married Jean Baptiste Dumas, and their other daughter Mathilde (1808–1882) married Jean Victoir Audouin. Erm7vc (talk) 02:32, 21 March 2020 (UTC)

Essai d’une classification naturelle des reptiles (emphasized importance of comparing anatomy in order to properly classify things. Four groupings for reptiles are chelonians, saurians, ophidians, and batrachians. Batrachians are no longer considered reptiles, they are amphibians)

Worked with Cuvier to date fossils. Essai sur la geographie mineralogique des environs de Paris. Nine formations with ‘Chalk’ being the oldest. After that was Argile Plastique (a clay without any fossils), then Calcaire grossier (a series of limestone layers) which had mostly marine mollusk fossils. Then next layer was Calcaire silicieux (another layer with no fossils), followed by Formation gypseuse (the layer where cuvier was got a bunch of vertebrate fossils and some freshwater shells. There was a distinct lack of marine shells). The next layer indicated a return of the ocean as marine fossils reappeared in the Sabels et Gres marins layer. After Gres sans coquilliers (a sandstone layer with no fossils), freshwater shell emerged again in Terrain d’eau douce (indicating a change in conditions again. This was the highest regularly stratified deposit.). They last layer identified was a superficial one, filled with extinct species that were very modern when compared with the other layers, called Limon d’aterrissement. Brongniart’s work proved that the layers above the chalk has taken a long time to form and so it extended the geological time that has elapsed since the chalk ends. His discovery that the strata alternates between salt and fresh water disproved the theory that strata was deposited by a shrinking ocean. Cuvier used the water thing to say changing water level caused plant extinctions. Brongniart also used fossils for the correlation of strata in different areas more precisely than the existing lithology. He stressed the use of fossils over lithology or position for dating due to the problem of geological facies.

First to classify tertiary formations. Life: studied at ecole des mines and ecole de medecin. Assisted uncle who taought chemistry, served in medical forces. Came back and became mining engineer. Then professor of natural history. Became chief mining engineer then chair of minerology at natural history museum. Revived factory by introducing new colors.

Biographical encyclopedia of scientists: also stopped production of soft-paste ware in addition to making a wide range of new colors.

Facts first approach: Uncle Antoine-Louis Brongniart (1742–1804), a professor at the Jardin des plantes. Served as pharamasist in Pyrenees 1793–1794. Became mine inspector when he got back. Alexandre married Cecile Coquebert de Montbret (1782–1862), the daughter of the French consul to England. Their son Adolphe (1801–1876) became a major figure in the study of paleobotany. Daughter Hermine (1803–1890) married the distinguished chemist Jean Baptiste Dumas (1800–1884). Another daughter Mathilde (1808–1882) married the zoologist Jean Victor Audouin (1797–1841). Alexandre Brongniart is buried in the famous Père-Lachaise cemetery, designed by his father.

1. What does the article do well? Is there anything from your review that impressed you? Any turn of phrase that described the subject in a clear way? Great notes here! You've got a lot to work with in terms of your additions. Why is there a french phrase? Is that a book title? Remember to cite that correctly. 2. What changes would you suggest the author apply to the article? Why would those changes be an improvement? Your notes are great, just flesh them out so they're more narrative, of course. And cite after each statement. 3. What's the most important thing the author could do to improve the article? Flesh it out! Work from your sandbox from now on. Copy your work over, if you like.
