Anthony Wood devoted his life to documenting the history of Oxford and its colleges, producing works such as 'Athenae Oxonienses'. His meticulous research preserved biographies of scholars, clergy, and prominent figures of his time. Wood's writings offered insight into 17th-century English intellectual life and remain valuable resources for historians. Despite controversies over his methodology and political views, his dedication to archival work set standards for English antiquarianism. He continued his research until his death in 1695.

Born in 1706, Émilie du Châtelet became a leading figure in the French Enlightenment with her groundbreaking work in mathematics and physics. She translated and provided extensive commentary on Isaac Newton's Principia Mathematica, making its insights accessible to the European scientific community. Her original writings on the nature of fire and energy prefigured principles of thermodynamics. She maintained a lifelong intellectual partnership with Voltaire, collaborating on both experimental and philosophical projects. Tragically, she died in 1749 following complications from childbirth, but her legacy endures as a pioneer for women in science and a key contributor to modern physics.

Born in Penzance in 1778, Sir Humphry Davy rose to prominence with his experiments in electrochemistry and element isolation. In 1807, he became the first to isolate potassium and sodium by passing electric currents through their molten salts. His invention of the Davy lamp in 1815 greatly improved safety for coal miners by reducing the risk of explosive gases. A gifted lecturer, he was elected President of the Royal Society and was knighted for his contributions to science. Davy mentored young Michael Faraday, shaping the next generation of experimentalists, and his work laid foundational principles for modern chemistry.

Born in 1797 in Albany, New York, Joseph Henry pioneered studies in electromagnetism, independently discovering the principle of electromagnetic induction. His work on electromagnetic relays laid the groundwork for the development of the electric telegraph. In 1846, he was appointed the first Secretary of the Smithsonian Institution, shaping its mission to increase and diffuse knowledge. Henry’s research and leadership extended to his professorship at Princeton University, where he influenced future generations of scientists. The SI unit of inductance, the henry, was named in his honor, cementing his legacy in the history of physics.

Alexander Emanuel Agassiz was a Swiss-American scientist who made significant contributions to the study of fish and marine ecosystems. Born in Neuchâtel and son of the famed biologist Louis Agassiz, he carried on his father's scientific legacy at Harvard's Museum of Comparative Zoology. Agassiz organized and led numerous marine expeditions in the Gulf Stream, collecting thousands of specimens and advancing the field of ichthyology. He also applied his engineering skills to design the first large marine railway in America to service ships on dry land. As a professor and museum director, he published extensively on marine biology and helped establish the discipline in the United States.

Sophus Lie was a pioneering Norwegian mathematician who founded the theory of continuous symmetry, known today as Lie groups and Lie algebras. He studied at the University of Christiania and later served as a professor at the University of Leipzig. His work provided the mathematical framework for understanding symmetries in geometry and physics. Lie's theories laid the groundwork for modern theoretical physics, including quantum mechanics and relativity. His influential publications and lectures shaped the development of algebra and geometry in the late nineteenth century.

Pierre Paul Émile Roux was a French physician and immunologist who collaborated closely with Louis Pasteur. He co-founded the Pasteur Institute in 1888 and served as its first director of research. Roux developed one of the first effective diphtheria antitoxins, saving countless lives. His work in bacteriology and vaccine research laid key foundations for modern immunology. Roux also trained a generation of scientists and expanded the Institute into a world-renowned center for infectious disease research.

Mary Cartwright was a trailblazing English mathematician who collaborated with J. E. Littlewood to lay the groundwork for modern chaos theory through her study of non-linear differential equations. During World War II, she applied her mathematical expertise to radar research at the Royal Aircraft Establishment. In 1960, she became the first female president of the London Mathematical Society and was honored with a Dame Commander of the Order of the British Empire. Her research has had a lasting impact on fields ranging from physics to engineering, cementing her reputation as a pioneer in dynamical systems.

Russell C. Newhouse was an American pilot and engineer whose work supported advancements in aeronautical design and flight safety. Throughout his career, he collaborated on technical innovations that improved aircraft performance and reliability. His dual expertise bridged the gap between engineering theory and practical aviation applications. Though much of his work remained behind the scenes, his influence was felt across military and civilian flight operations.

Willard Frank Libby revolutionized the field of archaeology and geology by inventing radiocarbon dating, a technique that accurately determines the age of organic materials. For this groundbreaking work, he received the Nobel Prize in Chemistry in 1960. As a professor at the University of Chicago, Libby also made significant contributions to nuclear chemistry and environmental science. His legacy endures in the countless scientific disciplines that rely on radiocarbon dating for research.

Kenneth Onwuka Dike was the first African Vice-Chancellor of the University of Ibadan and a founding figure of the Nigerian Historical Society. His scholarship emphasized indigenous sources and perspectives, challenging colonial narratives of African history. Dike’s works, including 'Trade and Politics in the Niger Delta', laid the foundation for modern African studies and inspired generations of scholars across the continent.

Kenneth E. Iverson was a Canadian computer scientist best known for developing the APL programming language. He worked at IBM as an IBM Fellow, where he refined APL's unique concise notation and array processing capabilities. In 1979, Iverson was awarded the ACM Turing Award for his contributions to programming language design. He also co-developed the J programming language, extending ideas from APL into new paradigms. His work has had a lasting impact on array programming, influencing modern languages and data analysis tools. Iverson's innovative notation and approach to problem-solving continue to inspire computer scientists worldwide.
