Born on 5 June 1646 in Venice, Elena Cornaro Piscopia was a prodigious scholar from a noble family. She studied languages, theology, and philosophy, and excelled in mathematics from a young age. In 1678, she became the first woman in Europe to earn a Doctor of Philosophy degree from the University of Padua. Her academic achievements challenged gender norms and inspired future generations of women scholars. Cornaro published works on philosophy, mathematics, and classical literature, though few survive. She died in 1684, leaving a pioneering legacy in higher education and women's intellectual history.

Pierre Jean George Cabanis (1757–1808) was a pioneering French physiologist and philosopher. He argued that mental processes have a physical basis in the nervous system and sought to unify medicine, biology, and ethics. His influential work Rapports du physique et du moral de l’homme explored the interplay between the body and the mind. Cabanis held various government positions during the French Revolution and contributed to the reorganization of medical education. His ideas anticipated developments in neuroscience and laid the groundwork for modern physiological psychology.

Johan Gadolin (1760–1852) was a Finnish chemist, physicist, and mineralogist who made fundamental contributions to analytical chemistry. In 1794 he identified a new rare earth oxide in a mineral from Ytterby, later named yttrium in his honor. As a professor at the University of Åbo, Gadolin advanced studies in mineral analysis and helped establish Finland’s scientific community. He published pioneering research on the composition of clays and ores, influencing later geochemists. His work laid the foundation for the separation of rare earth elements and their use in modern technologies.

Christian Lobeck (1781–1860) was a leading German philologist and academic particularly renowned for his work in ancient Greek language and religious practices. As a professor at the University of Bonn, he published influential works such as Aglaophamus, which examined Greek cult ceremonies and theology. His rigorous analysis of Greek grammar and lexicon advanced the study of classical texts and influenced generations of scholars. Lobeck’s commitment to textual criticism helped establish modern philology as a discipline. He also made significant contributions to Homeric scholarship and the understanding of Greek linguistic development.

John Couch Adams (1819–1892) was an English mathematician and astronomer celebrated for predicting the existence and position of Neptune through mathematical calculations. Working independently of Urbain Le Verrier, Adams analyzed irregularities in Uranus’s orbit to infer a new planet’s gravitational effects. His work led British astronomers to search for and ultimately observe Neptune in 1846. A fellow of the Royal Society, Adams also served as Lowndean Professor of Astronomy at Cambridge and contributed to theoretical celestial mechanics. He published influential research on lunar theory and elliptic functions that advanced mathematical physics.

Allvar Gullstrand (1862–1930) was a Swedish ophthalmologist and optician who received the Nobel Prize in Physiology or Medicine in 1911. He was recognized for his outstanding research on the optical structure of the eye and for improvements in ophthalmic instruments. Gullstrand developed mathematical models describing the eye’s lens system and clarified the role of astigmatism in vision defects. His inventions included advanced slit lamp apparatus and techniques for measuring refractive errors. He served as a professor at the University of Uppsala, mentoring future generations of ophthalmologists. Gullstrand’s contributions laid the foundation for modern clinical ophthalmology and optical engineering.

Isaac Heinemann was born in 1876 in Germany and became one of the foremost scholars of Jewish studies in the 20th century. After completing his education in Europe, he emigrated to Palestine, where he joined the Hebrew University of Jerusalem faculty as a professor of rabbinic literature and theology. His extensive research on Hellenistic Judaism and medieval Jewish philosophy produced influential publications that remain references in the field. Heinemann mentored generations of students, helping to establish Jewish studies as a respected academic discipline. He passed away in 1957, leaving a lasting impact on biblical scholarship and Jewish intellectual life.

Born in 1883 in Cambridge, John Maynard Keynes studied at Eton and King’s College, Cambridge, before becoming one of the most influential economists of the 20th century. His seminal work, The General Theory of Employment, Interest and Money, challenged classical economics by advocating active government intervention to manage economic cycles. Keynes’s ideas informed the New Deal policies in the United States and post-war economic planning in Europe. He also played a key role in the 1944 Bretton Woods Conference, helping to establish the International Monetary Fund and World Bank. Keynes’s legacy endures in the principles of Keynesian economics, which continue to guide fiscal policy worldwide.

Born in 1899 in Cincinnati, Otis Barton studied engineering before joining the New York Zoological Society. Alongside biologist William Beebe, he designed the bathysphere, the first deep-sea submersible for humans. They achieved record-breaking descents off the coast of Bermuda, observing marine life in its natural habitat. Barton's innovations laid the foundation for modern ocean exploration and submersible technology. He authored books and consulted on films chronicling his undersea adventures, bringing the deep sea to the public. His pioneering spirit inspired future generations of oceanographers and explorers. Barton passed away in 1992, leaving a legacy of discovery and innovation.

Born in 1900 in Budapest, Gabor studied engineering and physics before fleeing to England in the 1930s. In 1947, while working at British Thomson-Houston, he invented holography for recording three-dimensional images. His breakthrough laid the groundwork for applications in imaging, telecommunications, and data storage. He received the Nobel Prize in Physics in 1971 for his pioneering work in holography. Throughout his career, Gabor held numerous patents in electron optics and communication theory. He was elected a Fellow of the Royal Society and influenced generations of optical scientists. Gabor died in 1979, but his invention continues to impact technology and the arts.

Born in 1912, Dean Amadon developed an early passion for raptors and bird studies. He served for decades as a curator and researcher at the American Museum of Natural History in New York. Amadon authored seminal works on eagles, hawks, and falcons, advancing ornithological knowledge. His field research and taxonomic revisions earned him international recognition among scientists. He collaborated on numerous scientific papers and helped establish conservation strategies for raptors. Amadon mentored generations of ornithologists and contributed to professional societies. He passed away in 2003, leaving a lasting legacy in the study and conservation of birds of prey.

Beatrice de Cardi was born in London and studied Persian languages and archaeology at University College London. From the 1940s onwards, she led archaeological surveys in the Persian Gulf, Oman, and Baluchistan, uncovering evidence of ancient trade routes and settlements. She served as secretary and later president of the Council for British Archaeology, advocating for archaeological conservation worldwide. De Cardi also worked with UNESCO on archaeological projects across the Middle East and South Asia. Throughout her career, she published extensively on maritime archaeology and cultural heritage. She remained active in fieldwork well into her later years and passed away in 2016 at the age of 102.
