Abu Bakr Muhammad ibn Zakariya al-Razi (865–925), known as Rhazes, was a Persian polymath celebrated for his pioneering contributions to medicine, chemistry, and philosophy. He authored the comprehensive medical encyclopedia 'Al-Hawi', which influenced medical practice for centuries. Rhazes is credited with early descriptions of smallpox and measles, earning him recognition as a founder of pediatrics and infectious disease study. His alchemical works advanced laboratory techniques and the classification of substances. A prolific writer, he produced over 200 treatises, blending empirical observation with philosophical inquiry. His rational approach inspired both Islamic and European scholars throughout the Middle Ages and Renaissance.

Friedrich Martens was a leading scholar of international law in the late 19th century. He authored the influential 'Principles of International Law of Civilized Nations' and drafted key legal texts. Martens represented Russia at the Hague Peace Conferences, where his ideas informed the Martens Clause. As a diplomat, he negotiated treaties that guided the conduct of nations in conflict. His legacy endures in the foundations of today’s international legal framework.

Giuseppe Peano defined the axioms that underpin the natural numbers and formal arithmetic. His work in symbolic logic laid groundwork for future developments in mathematical theory and computation. Peano also introduced the space-filling curve that challenged conceptions of dimensionality. He authored the 'Formulario Mathematico,' an influential compendium of mathematical formulas. Peano’s teaching at the University of Turin inspired a generation of European mathematicians.

James Henry Breasted organized major archaeological expeditions in Egypt and the Near East. He wrote the landmark 'Ancient Records of Egypt,' making pharaonic history accessible. In 1919, Breasted established the University of Chicago’s Oriental Institute to advance interdisciplinary research. His scholarship bridged ancient civilizations with contemporary academic study. Breasted’s work laid foundations for modern archaeological methodology and education.

Bosch was instrumental in developing the Haber-Bosch process for ammonia synthesis, revolutionizing fertilizer production. As an executive at BASF, he implemented high-pressure chemical processes on an industrial scale. He shared the 1931 Nobel Prize in Chemistry for his contributions to chemical engineering. His innovations significantly boosted global agricultural output and food supply. Bosch also advanced research infrastructure and mentored a generation of scientists. His work laid the foundation for modern industrial chemistry.

McCormick graduated from MIT with one of the first women’s degrees in biology. She used her considerable inheritance to support Margaret Sanger’s birth control advocacy. Her financial backing was vital for the clinical trials that led to the first oral contraceptive. Beyond contraceptive research, she funded women’s rights and educational initiatives. Her philanthropy helped transform reproductive health and autonomy for women worldwide. She remains a pioneering figure in both science and social activism.

Lillie conducted pioneering biological research on marine invertebrates during the 1910-1913 expedition. He collected and cataloged Antarctic plankton and sea-ice organisms, expanding scientific knowledge of polar ecosystems. His fieldwork provided critical data on species adaptation to extreme environments. After returning, he continued research at the Marine Biological Association laboratory in Plymouth. He published influential findings that deepened understanding of marine biology. Lillie exemplified the dual roles of scientist and explorer during the Heroic Age of Antarctic exploration.

Born in Budapest in 1895, Alföldi developed an early interest in classical antiquity. He studied and taught at institutions across Europe, including chairs at Basel and Princeton. Alföldi's meticulous analysis of Roman coinage reshaped understanding of imperial propaganda and chronology. His publications on Augustus and the Julio-Claudian dynasty remain influential in ancient history studies. He combined archaeological fieldwork with numismatic evidence to illuminate social and political aspects of the Roman Empire. Alföldi mentored generations of historians and archaeologists, bridging continental scholarship traditions. He passed away in 1981, leaving a legacy of scholarship that continues to guide researchers today.

Norman F. Ramsey Jr. was an American physicist who invented the separated oscillatory fields technique. This breakthrough enabled precise measurements of atomic and molecular structures and led to atomic clocks. He shared the 1989 Nobel Prize in Physics for this innovation in molecular beam spectroscopy. Ramsey taught at Harvard University, mentoring generations of physicists. His work laid foundations for advances in timekeeping, quantum measurement, and fundamental physics research. He remained active in scientific advisory roles until his death in 2011.

Gordon Bashford was an English engineer noted for his pioneering work at the Rover and British Motor Corporation. He co-designed the first Range Rover, blending off-road capability with comfort and style. Earlier, he contributed to the development of the Morris Mini Traveller and Austin Seven. Bashford's designs helped shape post-war British automotive engineering excellence. His innovations influenced generations of 4x4 vehicles and compact cars. He is remembered as a key figure behind iconic British car models of the 20th century.

Born in 1918, Jelle Zijlstra studied economics and became a respected academic before entering politics. He served as Minister of Finance and later as Governor of the Netherlands Bank, influencing post-war economic policy. In 1966, he headed a caretaker government as Prime Minister, guiding the country through a period of social and economic change. Zijlstra was known for his fiscal expertise and steady leadership. After leaving office, he continued to serve in the Senate and advised on international financial matters. He died in 2001, remembered as a key figure in modern Dutch politics and economics.

Born in 1922, Roelof Kruisinga trained as a physician and psychiatrist before entering politics with the Christian Historical Union. He was appointed Minister of Health and Environment in 1971 and became Minister of Defence in 1973 under Prime Minister Joop den Uyl. Kruisinga oversaw key reforms in healthcare policy and modernization of the Dutch armed forces. After leaving ministerial office, he served as a member of the Council of State, advising on public policy. He was respected for his analytical approach and commitment to public service. Kruisinga died in 2012, leaving a record of significant contributions to Dutch medicine and politics.
