Born in Riom, France, in 1559. He joined the Society of Jesus in 1580 and became a leading scholar of the Jesuit order. Sirmond served as librarian to the French royal library and later to the Vatican. He edited and published critical editions of early Church Fathers’ writings. His scholarship laid foundations for modern patristic studies and historical research.

Born in 1710 in Strachan, Scotland, Reid studied at the University of Aberdeen. As a professor at King’s College, Glasgow, he challenged David Hume’s skepticism. Reid founded the Scottish Common Sense School of philosophy, emphasizing natural beliefs. He authored 'An Inquiry into the Human Mind on the Principles of Common Sense' in 1764. His work influenced philosophical and psychological thought on both sides of the Atlantic.

Born in 1809, Oliver Wendell Holmes Sr. rose to prominence as a Harvard professor and physician, advocating for handwashing to prevent puerperal fever. A member of the Fireside Poets, he penned essays, poems, and novels such as "The Autocrat of the Breakfast Table." Holmes's witty social commentary and lyrical verse made him a beloved literary figure. He also wrote on medical jurisprudence and championed public health reforms. His multifaceted career bridged science and letters, leaving a lasting impact on both disciplines.

Born in 1832, Rudolf Lipschitz made seminal contributions to mathematics, including the concept of Lipschitz continuity, which underpins modern analysis. He worked on bilinear forms, differential equations, and the theory of elasticity. As a professor at the University of Bonn, he influenced generations of mathematicians. His research on the motion of rigid bodies advanced classical mechanics. Lipschitz's work laid groundwork for functional analysis and impacted fields from physics to engineering. He remained active in teaching and scholarship until his death in 1903.

Born in 1835, John Hughlings Jackson revolutionized the understanding of neurological disorders through his study of epilepsy. He introduced the concept of Jacksonian seizures, tracing symptoms to specific brain regions. Jackson's hierarchical model of the nervous system influenced theories of cortical function and neuropsychology. As a physician at the National Hospital for Neurology and Neurosurgery, he trained many future neurologists. His meticulous clinical observations and writings shaped neurology as a distinct medical discipline. Jackson died in 1911, leaving a profound scientific legacy.

Born in 1856, Emil Kraepelin established the first systematic classification of mental disorders, distinguishing dementia praecox (later schizophrenia) from manic-depressive illness. He pioneered empirical methods and emphasized careful clinical observation. Kraepelin founded psychiatric research laboratories at Leipzig and Munich, mentoring students like Alois Alzheimer. His textbooks became foundational works in psychiatry and influenced the development of the DSM. Kraepelin's integration of biology and psychology reshaped mental health treatment and research before his death in 1926.

Born in 1869 in Cleveland, Ohio, Cushing studied medicine at Harvard and Johns Hopkins before embarking on a surgical career. He introduced innovative techniques for brain tumor removal and developed methods to measure intracranial pressure. His landmark monograph on pituitary disorders led to the identification of Cushing's disease. Cushing served as a professor at Harvard Medical School and influenced generations of surgeons through his teaching. He published extensively and catalogued thousands of brain specimens, creating a valuable research archive. His contributions established neurosurgery as a distinct and respected medical specialty.

Born in 1876 in Angola, New York, Carrier graduated from Cornell University with a degree in engineering. In 1902, he designed the first electrical air conditioning unit to control humidity in a printing plant. He patented the system in 1906 and founded the Carrier Engineering Corporation in 1915. Carrier’s technology revolutionized climate control in factories, offices, and homes, enabling year-round comfort and productivity. His work also laid the foundation for modern HVAC industries worldwide. Carrier remained active in his company until his death in 1950, and his name continues to be synonymous with air conditioning.

Born in Quebec in 1906, Parent was ordained as a Roman Catholic priest in 1933. He earned doctorates in theology and philosophy and joined the faculty of Université Laval, rising to dean and rector. In 1961, he chaired the Royal Commission on Education in Quebec, issuing the influential Parent Report in 1963. The report recommended major reforms, including secularization and modernization of Quebec's school system. His work laid the foundation for the Quiet Revolution's education changes, and he continued lecturing until his death in 1970.

Born in Los Angeles in 1927, Abell received his Ph.D. from UCLA, where he would later teach. He compiled the Abell Catalog of Rich Clusters of Galaxies based on the Palomar Observatory Sky Survey. As a professor, he taught astronomy for decades, authoring influential textbooks and papers on stellar and planetary astronomy. A passionate science popularizer, he co-authored books and guides to make astronomy accessible to the public. A founding fellow of the Committee for the Scientific Investigation of Claims of the Paranormal, he promoted skepticism and critical thinking. His contributions to astronomy and skepticism left a lasting impact when he died in 1983.

Niels Kaj Jerne was a distinguished scientist who transformed the field of immunology with his theoretical contributions. Born in 1911 in Denmark, he later worked in England and focused on the underlying principles of how the immune system recognizes and responds to pathogens. In 1984, Jerne was co-awarded the Nobel Prize in Physiology or Medicine for his network theory of the immune system. His work provided a foundational framework for modern immunological research and vaccine development. Jerne published numerous influential papers and mentored future leaders in the field. He passed away in 1994, leaving behind a legacy of intellectual rigor and scientific excellence.

Born in 1906, Olga Taussky-Todd made significant advances in matrix theory and number theory during a career that spanned Europe and the United States. She studied under prominent mathematicians in Vienna and was associated with the Vienna Circle, engaging with leading philosophical and scientific debates. After emigrating to America, she collaborated closely with her husband, mathematician John Todd, and held professorships at institutions like Caltech. Taussky-Todd published numerous influential papers and was celebrated for her mentorship of young mathematicians. Her work laid the groundwork for modern computational approaches in linear algebra. She passed away in 1995, leaving a lasting legacy in the mathematical community.
