He played a crucial role in advancing the field of natural history, particularly in the areas of anatomy and zoology. Daubenton's work focused on the classification and study of animal species, and he was instrumental in establishing the concept of comparative anatomy. His expertise and dedication to scientific inquiry earned him a reputation as a respected figure in the intellectual circles of his time.

Bernard de Jussieu was a French naturalist known for his contributions to botany. He began his career as a medical practitioner but found his true calling in botany. He made significant advancements in the classification of plants, including arranging the plants in the royal garden of the Grand Trianon based on his classification system. Jussieu was a member of the French Academy of Sciences and was recognized for his work by being elected a foreign member of the Royal Swedish Academy of Sciences. His botanical author abbreviation is B.Juss.

Félix-Archimède Pouchet was a French naturalist known for his controversial views on spontaneous generation of life. He served as the director of the Rouen Jardin des Plantes and later became a professor at the University of Rouen School of Medicine. Pouchet authored the influential work "Hétérogénie" in 1859, challenging Louis Pasteur's germ theory. He also wrote a comprehensive encyclopedia on the sciences, where he criticized Pasteur's theories. Pouchet's contributions to the study of cytology and his membership in the American Philosophical Society further highlight his impact in the scientific community.

Jean-Étienne Guettard was a renowned French naturalist and mineralogist known for his significant contributions to the fields of botany, geology, and mineralogy. He pioneered the concept of geological maps by correlating the distribution of plants with soils and subsoils, leading to groundbreaking discoveries about the Earth's structure. Guettard's work on mineral distribution, rock formations, fossils, and the effects of erosion on mountains established him as a respected figure in the scientific community. His achievements were recognized through prestigious memberships and influential publications that furthered the understanding of Earth sciences.

Antoine de Jussieu was a French naturalist, botanist, and physician. He studied at the University of Montpellier and traveled extensively through Spain, Portugal, and southern France.
