Karl Möbius was a pioneering German zoologist and ecologist known for introducing the concept of biocenosis, the study of biological communities. His research on oyster banks in the North Sea led him to examine interactions between species and their environments. Möbius served as director of the Museum für Naturkunde in Hamburg and published influential works on marine ecology. His holistic approach to studying ecosystems influenced the development of ecological science. Möbius's legacy endures in ecological theory and environmental studies.

James Murray was a Scottish lexicographer whose leadership established the Oxford English Dictionary as the preeminent English-language reference. After emigrating to England, he was appointed the dictionary's first editor in 1879. Murray organized a vast network of volunteer readers to collect citations and oversaw the compilation of definitions and etymologies. His meticulous approach and editorial vision guided the OED's initial volumes published in the late 19th century. Murray's work set new standards for lexicography and scholarly collaboration in the humanities.

Alfred Adler broke away from Sigmund Freud's circle to establish his own school of individual psychology. He introduced the idea that feelings of inferiority drive human behavior and development. Adler emphasized the importance of social interest and community feeling in mental health. He founded the Society for Individual Psychology in 1912 and lectured widely across Europe. His theories influenced education, psychotherapy, and the human potential movement. Adler's work laid groundwork for modern counseling and family therapy practices. He died in Scotland in 1937 while fleeing the rise of Nazism.

G. H. Hardy made seminal advances in pure mathematics, especially in number theory and analysis. He co-authored the Hardy-Weinberg equilibrium, a foundational concept in population genetics. Hardy's collaboration with Srinivasa Ramanujan yielded groundbreaking results on partitions and modular forms. In 1940 he published A Mathematician's Apology, a classic reflection on the aesthetics of mathematics. He held professorships at Cambridge and Oxford, mentoring numerous prominent mathematicians. Hardy advocated for the intrinsic beauty of pure research over practical applications. He retired in 1942 and left an enduring legacy in both mathematics and genetic theory.

Harry Nyquist was a Swedish-American engineer born in 1889. Working at Bell Telephone Laboratories, he formulated the Nyquist stability criterion essential to control theory. His work on signal transmission laid groundwork for the Nyquist–Shannon sampling theorem in communications. Nyquist's research established limits on data transmission rates over telephone lines. He authored seminal papers that shaped both telecommunications and feedback system design. His insights continue to influence digital signal processing and modern electronics. He died in 1976, recognized as a pioneering thinker in engineering and information theory.

Joseph Algernon Pearce was a Canadian astrophysicist born in 1893. He conducted pioneering research on stellar photometry and spectroscopy. As a senior researcher at the Dominion Astrophysical Observatory, he refined techniques for measuring stellar brightness. His publications contributed to more accurate catalogs of star magnitudes. He taught and mentored students, promoting the growth of Canadian astronomy. A member of the Royal Astronomical Society of Canada, he advocated for public engagement in astronomy. Pearce's work laid groundwork for future studies of stellar evolution. He passed away in 1988, leaving a legacy in observational astrophysics.

Ulf von Euler was a Swedish physiologist born in 1905. He received the Nobel Prize in Physiology or Medicine in 1970 for his work on neurotransmission. Von Euler identified noradrenaline as a neurotransmitter in the peripheral nervous system. His research elucidated the mechanisms of chemical signaling between nerve cells. He held academic positions at the Karolinska Institute and the University of Uppsala. Von Euler authored numerous influential papers on cardiovascular physiology. He mentored generations of researchers in pharmacology and neuroscience. He passed away in 1983, leaving a foundational legacy in modern neurophysiology.

Oleg Antonov was a Soviet engineer born in 1906. He founded the Antonov Design Bureau in 1946, which became renowned for transport aircraft. Antonov's first major success was the An-2 biplane, known for its rugged versatility. He went on to design record-setting cargo planes like the An-124 Ruslan and An-225 Mriya. His innovations advanced aerodynamics and structural design in aviation. Antonov also emphasized simplicity and reliability, making his aircraft popular worldwide. He led his bureau until his death in 1984, overseeing dozens of groundbreaking projects. His name lives on through Antonov State Company, a legacy in aerospace engineering.

An Wang immigrated to the U.S. in 1945 to pursue graduate studies at Harvard University. He earned his Ph.D. in physics in 1948, specializing in magnetic core memory. In 1951 he co-founded Wang Laboratories, initially focusing on calculating devices. Under his leadership, the company developed word processing systems that became industry standards in the 1970s and 1980s. Wang Laboratories grew into a Fortune 500 company, employing thousands worldwide. Wang's inventions in computer memory and display technologies sparked significant improvements in early computing. He remained CEO until 1983 and served on multiple academic advisory boards. His contributions helped shape the evolution of office computing and data processing.

Konstantin Feoktistov graduated from Moscow Aviation Institute and became a leading spacecraft designer. In 1964 he was selected for the Soviet space program and flew on Voskhod 1, the first mission to carry three crew members. During the flight, he conducted experiments in weightlessness and tested life-support systems. After his spaceflight, he served as a designer at OKB-1 under Sergei Korolev, working on Soviet lunar and space station projects. He later earned a doctorate for his research in space engineering. Feoktistov published numerous papers on spacecraft design and engineering. His contributions advanced the Soviet Union's capabilities in human space exploration.

Alfred Worden graduated from the United States Military Academy and served as a fighter pilot in the U.S. Air Force. Selected by NASA in 1966, he was the Command Module Pilot on Apollo 15, the fourth crewed mission to land on the Moon. During the mission, Worden conducted extensive photographic surveys and scientific experiments from lunar orbit. After retiring from NASA and the Air Force in 1975, he worked in aerospace consulting and lectured on space exploration. Worden passed away in 2020, celebrated for his contributions to one of NASA's most scientifically productive lunar missions.

Eric Foner is the DeWitt Clinton Professor of History at Columbia University, celebrated for his groundbreaking scholarship on 19th-century America. His 1988 work 'Reconstruction: America's Unfinished Revolution' earned the Pulitzer and Bancroft Prizes. Foner's extensive research has reshaped understanding of slavery, citizenship, and civil rights, influencing both academia and public discourse. He has authored or edited over 20 books and served as president of the American Historical Association. Foner’s clear writing and authoritative perspective have made him a leading voice on American history.
