He was the son of the geologist Alexandre Brongniart and grandson of the architect, Alexandre-Théodore Brongniart. Brongniart's pioneering work on the relationships between extinct and existing plants has earned him the title of father of paleobotany. His major work on plant fossils was his Histoire des végétaux fossiles (1828&ndash;37). He wrote his dissertation on the Buckthorn family (Rhamnaceae), an extant family of flowering plants, and worked at the Muséum national d'Histoire naturelle in Paris until his death. In 1851, he was elected a foreign member of the Royal Swedish Academy of Sciences. This botanist is denoted by the author abbreviation '''  Brongn. ''' when citing a botanical name.

Eichler and Adolf Engler, which was not superseded until the development of DNA research. In addition to his scientific and professorial labours, Brongniart held various important official posts in connection with the department of education, and interested himself greatly in agricultural and horticultural matters. With Jean Victoire Audouin and Jean-Baptiste Dumas, his future brothers-in-law, Brongniart founded the Annales des Sciences Naturelles, a peer-reviewed journal, in 1824.

Title: Alexandre Brongniart
Content:  He was born in Paris, the son of the architect Alexandre-Théodore Brongniart and father of the botanist Adolphe-Théodore Brongniart. In 1797, he became an instructor of natural history at the Central School of the Four Nations, and became the professor of mineralogy 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. He remained in charge of Sèvres, through regime changes, for 47 years. Brongniart introduced a new classification of reptiles and wrote several treatises on mineralogy and the ceramic arts. He also made an extensive study of trilobites and made pioneering contributions to stratigraphy by developing fossil markers for dating strata. He was elected a member of the American Philosophical Society in 1819 and a foreign member of the Royal Swedish Academy of Sciences in 1823.
