Born in 1528, Domingo Báñez entered the Dominican Order and became a professor at the University of Salamanca, the leading center of theological study in Spain. He rigorously defended the teachings of Saint Thomas Aquinas against alternative scholastic viewpoints during the Renaissance. Báñez's writings on divine grace, predestination, and human free will sparked significant controversy and influenced Church policy. He authored detailed treatises that contributed to the Thomistic revival, cementing his reputation as a masterful logician. His work extended beyond academia into pastoral care and ecclesiastical affairs. Báñez's influence persisted in Catholic theology, affecting debates well into the modern era.

Born in 1636 in Middelburg, Hermann Witsius studied theology at the universities of Utrecht and Leiden before becoming a professor at Franeker. He later held the chair of theology at Utrecht University, where he taught until his death. Witsius sought to bridge differences within the Dutch Reformed Church by promoting unity without compromising core doctrines. His most influential work, 'The Economy of the Covenants,' integrated biblical covenants into systematic theology and shaped covenantal thinking in Protestantism. He engaged in ecumenical dialogue with Anglican scholars, reflecting his moderate and conciliatory approach. Witsius's scholarly contributions left a lasting mark on Reformed theological tradition.

Guillaume Le Gentil was born in 1725 to a noble family in France. He developed a passion for astronomy and earned his doctorate from the University of Dijon. In 1761, he set sail to observe the transit of Venus, but was thwarted by war and monsoon rains. Undeterred, he waited eight years for the next transit in 1769, enduring a prolonged stay in India that left him stranded for over a decade. Upon his return to France, he discovered that he had been declared dead and his estate seized. His meticulous observations of planetary transits and his perseverance in the face of adversity left a lasting mark on the study of astronomy.

Ernst von Fleischl-Marxow was born in 1846 in Vienna, Austria. He conducted groundbreaking experiments on sensory nerves and the electrical properties of tissues. His work on animal electricity and nerve conduction advanced the understanding of neurophysiology. Serving as a professor at the University of Vienna, he mentored many future scientists. Later in life, he suffered from severe pain and became one of the first notable cases of morphine addiction. Despite his struggles, his scientific publications left a lasting legacy in medical science. He died in 1891, remembered for his methodological rigor and innovations in physiological research.

Herman Adolfovich Trautschold was born in 1817 and studied natural sciences in Germany before moving to Russia. He became a professor at the Mining Institute in Saint Petersburg, where he conducted pioneering research on Paleozoic and Mesozoic fossils. His detailed monographs on ammonites and brachiopods helped to refine the geological time scale. Trautschold's field expeditions across the Ural and Caucasus regions yielded a rich collection of specimens. He published influential catalogs that became standard references for European paleontology. Beyond his research, he was a respected teacher who trained a generation of Russian geologists. He died in 1902, leaving a substantial body of work that continues to inform paleontological studies.

Born in 1857, Charles P. Lukis studied medicine in the United Kingdom before joining the Indian Medical Service. In 1913, he established the Indian Journal of Medical Research, which became a leading forum for medical studies in British India. He later rose to serve as Director-General of the Indian Medical Service, overseeing public health and medical research across the subcontinent. Lukis championed improvements in tropical medicine and hygiene and played a key role in advancing healthcare infrastructure in India. His contributions laid the foundation for modern medical research institutions in the region.

Born in 1847 in Rome, Marchiafava became a professor of pathology at the University of Rome. He collaborated with Angelo Celli to advance knowledge of malaria, including the description of the parasite in red blood cells. Marchiafava first identified the brain disorder now known as Marchiafava-Bignami disease. His research extended to various neurological and infectious diseases, contributing to modern clinical pathology. Marchiafava's work laid the groundwork for advances in tropical medicine and neuropathology in the early 20th century.

Born in 1874 in Basel, Rüdin studied under Emil Kraepelin and focused on the hereditary aspects of mental illness. He directed the Genetic Department at the Psychiatric Hospital of Munich, conducting influential twin and family studies. Rüdin co-founded the German Society for Racial Hygiene and his theories later informed Nazi eugenic policies. Despite his scientific contributions to psychiatric genetics, his legacy is marred by his support for racial hygiene. Rüdin's research remains a subject of study and controversy in the history of psychiatry and genetics.

Born in Kobe, Mieko Kamiya studied medicine at Kyoto University and became a pioneering figure in Japanese psychiatry. Influenced by existential philosophy, she wrote extensively on the concept of ikigai (life purpose), notably in her classic 'On the Meaning of Life'. Kamiya advocated for humane mental health care, contributed to child psychiatry, and authored essays and diaries that offer profound psychological and cultural insights.

Born in 1893 in Budapest, Szent-Györgyi earned his medical degree and conducted extensive research into cellular oxidation. He discovered and isolated ascorbic acid (vitamin C), demonstrating its role in preventing scurvy. In 1937 he was awarded the Nobel Prize in Physiology or Medicine for these groundbreaking findings. During World War II, he aided the Hungarian resistance before emigrating to the United States. He held research positions at Harvard and the National Institutes of Health, where he explored the biochemistry of the citric acid cycle. Szent-Györgyi's work laid the foundation for modern cell biology, and he remained an active scientist until his death in 1986.

Lajos Für (1930-2013) was a Hungarian historian, academic, and politician who served as Minister of Defence from 1990 to 1994 during Hungary's transition to democracy. A professor of modern European and Hungarian history, he authored numerous scholarly works and taught at several universities. Für co-founded the Hungarian Democratic Forum, playing a pivotal role in the country's post-Communist political landscape. As defence minister, he guided the reform and integration of the Hungarian armed forces to meet NATO standards. After leaving politics, he returned to academia, continuing his research and writing. Für was admired for bridging scholarship and public service, influencing both historical scholarship and national policy. His contributions remain significant in Hungary's contemporary history.

John Postgate was born in 1922 and became a leading figure in microbiology. He served as a professor at University of Bath, researching the role of microbes in nutrient cycles. Postgate authored influential textbooks, including Microbes and Man, used in universities worldwide. His work on nitrogen-fixing bacteria advanced understanding of soil health and agriculture. He was elected Fellow of the Royal Society for his contributions to science. Postgate mentored generations of microbiologists and campaigned for public science education. He remained active in research and writing until his death in 2014.
