Throughout his career, Jacob made significant contributions to the field of genetics, leaving a lasting impact on scientific knowledge.

Roger Guillemin was a pioneering French-American neuroscientist known for his groundbreaking research on neurohormones. His work earned him numerous prestigious awards, including the National Medal of Science in 1976 and the Nobel Prize for Medicine in 1977, which he shared with Andrew Schally and Rosalyn Sussman Yalow. Guillemin's contributions significantly advanced the understanding of hormone signaling and its impact on various physiological processes, leaving a lasting impact on the field of neuroscience and endocrinology.

Alain Bombard was a renowned French biologist, physician, and politician. He gained fame for his daring solo voyage across the Atlantic Ocean in a small boat without provisions, testing his theory that a human could survive such a journey. This bold experiment was driven by his desire to save lives of those lost at sea. In addition to his adventurous spirit, Bombard also served as a Member of the European Parliament for France, representing the Socialist Party from 1981 to 1994.

Jacques Lucien Monod was a renowned French biochemist known for his groundbreaking work in molecular biology. Alongside François Jacob and André Lwoff, he received the Nobel Prize in Physiology or Medicine in 1965 for their discoveries on genetic control of enzyme and virus synthesis. Monod's research on the E. coli lac operon provided key insights into gene regulation mechanisms, particularly regarding the role of repressor proteins and messenger RNA molecules. His contributions laid the foundation for our understanding of transcriptional regulation and established him as a pioneer in the field of molecular biology.

René Antoine Ferchault de Réaumur was a prominent French entomologist and writer known for his significant contributions to the fields of entomology and natural history. He is particularly renowned for his work in the study of insects, where he made groundbreaking discoveries and advancements. De Réaumur's most enduring legacy is the introduction of the Réaumur temperature scale, which provided a standardized method for measuring temperature. His work has had a lasting impact on the scientific community and continues to be influential in the study of insects and temperature measurement.

Bernard Germain de Lacépède was a French naturalist and freemason known for his significant contributions to Comte de Buffon's Histoire Naturelle. He held various prestigious positions within the scientific community, such as being a professor of ichthyology at the Muséum National d'Histoire Naturelle in Paris. Lacépède authored numerous works on natural history, focusing particularly on fish and reptiles. His dedication to scientific research and collaboration with other prominent naturalists solidified his reputation as a respected figure in the field of natural sciences.

Jean Edmond Cyrus Rostand was a prominent French biologist, historian of science, and philosopher. He made significant contributions to the field of biology, particularly in areas such as amphibian embryology, parthenogenesis, and teratogeny. Rostand was also known for his work as a science writer, covering topics in popular science, history of science, and philosophy. He actively opposed pseudoscience, the misuse of science for warfare, racism, and advocated for human equality and freedom. His interest in ethics and morality in biology was reflected in his writings and activism.

Jules A. Hoffmann is a prominent French biologist known for his groundbreaking research in the field of innate immunity using insects as model organisms. He holds a faculty position at the University of Strasbourg and serves as a research director at the National Center of Scientific Research (CNRS) in Strasbourg, France. Hoffmann's work on the Toll gene in fruit flies, alongside Bruno Lemaitre, led to the discovery of Toll-like receptors in mammals, shedding light on how the immune system responds to pathogens and triggering an immune response.

Félix Dujardin was a renowned French biologist known for his significant contributions to the study of protozoans and other invertebrates. Throughout his career, he conducted extensive research that greatly advanced the understanding of these organisms, particularly in the fields of biology and zoology.
