Adolphe Théodore Brongniart (January 14, 1801 _ February 18, 1876) was a Frenchbotanist. 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 (1828–37). In 1827 he published the first account of the development of pollen.
Brongniart founded the Annales des Sciences Naturelles in 1824 with Jean Victoire Audouin and Jean_Baptiste Dumas. He also founded the Société Botanique de France in 1854, and was its first president.
ADOLPHETHEODOREBRONGNIART (1801-1876), French botanist, son of the geologist Alexandre Brongniart, was born in Paris on the 14th of January 1801.
Brongniart was an indefatigable investigator and a prolific writer, so that he left behind him, as the fruit of his labours, a large number of books and memoirs.
Brongniart, no doubt, was overwhelmed with the continually increasing magnitude of the task that he had undertaken.
AdolpheBrongniart is considered to be the founder of French paleobotany (the study of fossil plants), but his influence and that of his family extends far beyond the borders of France.
Brongniart used comparative anatomy of fossil and living plants to better understand the classification of the fossils and was clearly a pioneer in the area of using thin sections to study the internal structure of fossil plants.
AdolpheBrongniart was the first to publish a classification of all known fossil plants and pioneered the use of comparative anatomy in the study of plant fossils.
