Nicolas-Claude Fabri de Peiresc was a French scholar renowned for his work in astronomy and history. He established one of the first scientific correspondence networks in Europe, exchanging ideas with leading figures such as Galileo Galilei and Johannes Kepler. In 1610, he made one of the earliest telescopic observations of the Orion Nebula. As an antiquarian, he collected manuscripts, coins, and inscriptions, significantly advancing the study of classical antiquity. He served as a counselor to Marie de' Medici and led archaeological expeditions in Provence. His interdisciplinary scholarship laid the foundations for modern research institutions.

Pieter Burman the Younger was a leading Dutch scholar born in Amsterdam in 1714. He succeeded his uncle as professor of Greek and Latin literature at the University of Leiden. He published authoritative editions of works by Virgil, Horace, and other classical authors, emphasizing textual criticism and scholarly accuracy. As university librarian, he expanded the institution's manuscript collections and research resources. His meticulous philological research helped shape the standards of classical scholarship in the 18th century. Burman's work remains influential in the study of ancient texts.

Willy Ley was a German-American historian of science and author, renowned for his accessible books on rocketry and spaceflight. After fleeing Nazi Germany in 1935, he settled in the United States and became a leading advocate for space exploration through popular science writing. Ley collaborated with rocket pioneers like Wernher von Braun and wrote seminal works such as Rocketry and Space Travel. His clear explanations and visionary outlook inspired public interest in the possibilities of space travel. He also contributed to zoology studies, reflecting his eclectic scholarly interests. Ley's writings bridged the gap between technical research and general audiences, cementing his legacy as a pioneer of modern space journalism.

Minor White was a seminal American photographer who played a major role in elevating photography as an art form. His introspective black-and-white images, often exploring themes of nature and spirituality, earned him critical acclaim. As a co-founder of Aperture magazine, he influenced generations of photographers through editorial guidance and essays. White also taught at the California School of Fine Arts and Massachusetts Institute of Technology, mentoring many prominent artists. His practice of 'equivalence'—using photographs to evoke personal emotions—became a cornerstone of photographic theory. Throughout his career, he organized numerous exhibitions and workshops, leaving a lasting impact on the photography community.

Born in Winden am See in 1919, Gerhard Ringel studied mathematics at the University of Vienna. He is best known for solving the Heawood Map-Coloring Conjecture through the Ringel–Youngs theorem. His work on combinatorial topology and graph embeddings advanced the field of discrete mathematics. Ringel held professorships at the University of Hamburg and mentored a generation of mathematicians. He authored influential papers on map coloring and surface embeddings that continue to shape research. He received recognition from international mathematical societies for his groundbreaking research. Ringel's legacy endures in the many theorems and problems bearing his name.

Gu Chaohao (1926–2012) was a prominent Chinese mathematician and academician of the Chinese Academy of Sciences. He specialized in partial differential equations and made significant contributions to the mathematical foundations of fluid mechanics. Over his career, he published influential papers that advanced both theoretical and applied mathematics. Gu was dedicated to education, mentoring many students and helping to establish strong mathematics programs at leading Chinese universities. He held leadership roles in academic institutions and mathematical societies, guiding research directions and fostering collaboration. His work helped raise the international profile of Chinese mathematics and inspired subsequent generations of scholars.

Mick Aston (1946–2013) was an English archaeologist celebrated for his expertise in landscape archaeology and his charismatic presence on the long-running television show 'Time Team.' A professor at the University of Bristol, he conducted extensive research on Roman Britain and medieval settlement patterns. Aston’s distinctive sweaters and engaging explanations made archaeology accessible to a wide audience. He co-founded several archaeological trusts and championed community-based excavation projects across the UK. His academic publications influenced field survey methods and the study of past landscapes. Beyond television, Aston lectured internationally and inspired both amateur and professional archaeologists. His passing was widely mourned by colleagues, students, and fans of 'Time Team,' leaving a lasting legacy in public archaeology.

Sir James Martin (1933–2013) was a computer scientist and author whose contributions helped shape software engineering and information systems. Educated in Yorkshire and later working at IBM and NASA, he developed the Structured Systems Analysis and Design Method (SSADM), adopted by governments and industries worldwide. Martin authored over 80 books on computing, including influential titles like 'The Wired Society' and 'Applied Data Communications'. He founded the consultancy James Martin Associates, advising Fortune 500 companies on data processing and strategic IT planning. Knighted in 2000, he also championed advances in artificial intelligence and data modeling. His clear writing and practical methodologies made complex concepts accessible to both managers and developers. Martin’s legacy endures in the frameworks and standards still used in modern software development.
