Born in 845, Sugawara no Michizane excelled in Chinese literature and poetry, earning high regard at the imperial court. He held key government positions, including Minister of the Right, where he advocated for cultural and administrative reforms. His political rivals orchestrated his exile to Dazaifu in Kyushu, where he continued writing poetry and diaries. After his death in 903, calamities in Kyoto were attributed to his angry spirit, leading to his deification as Tenjin, the god of scholarship. Shrines dedicated to Tenjin dot Japan, and his legacy endures in the annual Tenjin festivals and scholar pilgrims who pray for academic success.

Andrew Melville (1545–1622) was a leading figure in the Scottish Reformation and a noted humanist scholar. Educated in France, he brought continental learning to Scotland and challenged traditional academic structures. As Principal of the University of Glasgow, he introduced new curricula and strengthened the faculty. Melville was a fierce advocate of Presbyterianism and clashed with monarchs over church governance. His works on theology and Latin poetry were widely read across Europe. He spent years in exile for defending ecclesiastical independence, yet continued to write and teach. Melville's legacy endures in Scottish education and Reformed theology.

Born in 1744 in Bazentin, France, Lamarck served briefly as a soldier before turning to science. He became a professor of zoology at the National Museum of Natural History in Paris and coined the term 'biology'. In 1809 he published 'Philosophie Zoologique', proposing that organisms adapt to their environments and pass on traits to offspring. Although his mechanism of evolution was later superseded, his work laid important groundwork for the theory of evolution. Lamarck also contributed to invertebrate taxonomy and helped popularize natural history in France.

Born in 1779 in Offenburg, Germany, Oken studied medicine and developed a passion for natural history. He published influential works on plant classification and the interrelation of living organisms. Oken founded the journal 'Isis', which became a major forum for German naturalists. He proposed that all animals derive from microscopic vesicles, anticipating aspects of cell theory. His holistic view of nature and contributions to ornithology influenced biological thought in the 19th century.

Born in 1818 on Nantucket Island, Mitchell developed a passion for astronomy under her father's tutelage. In 1847 she discovered a comet that became known as 'Miss Mitchell's Comet', earning her a gold medal from the King of Denmark. She joined Vassar College in 1865 as its first astronomy professor, where she mentored many women in the sciences. Mitchell co-founded the American Association for the Advancement of Science and advocated for women's education. Her achievements opened doors for future generations of female scientists.

Born in Patras, Logothetopoulos studied medicine at the University of Athens and specialized in neurosurgery in Germany. He returned to Greece as a respected physician and professor, publishing research on surgical techniques. During the German occupation of Greece in World War II, he was appointed Prime Minister of the collaborationist government from 1941 to 1943. His tenure was marked by complex political pressures and controversy over his role in occupied Greece. After the war, he was tried for treason but ultimately acquitted and returned to medical practice and teaching. He contributed significantly to the development of neurosurgery in Greece before his death in 1961.

Otto Toeplitz was a professor at the University of Breslau and later at the University of Bonn, where he established a leading Mathematical Seminar. He introduced Toeplitz matrices and operators in functional analysis, with lasting impact on fields such as signal processing and probability theory. A pioneer in mathematical education, he co-authored the influential text 'Algebraische Analysis' and mentored future luminaries like Erich Hecke. As a Jewish academic under the Nazi regime, he was dismissed from his position in 1935 and emigrated to Palestine. He continued teaching at the Hebrew University of Jerusalem until his death in 1940. His contributions remain central to modern analysis and operator theory.

George de Hevesy was a Hungarian chemist who became a naturalized German citizen. He introduced the use of radioactive isotopes to trace chemical processes and studied radiochemistry and biochemistry. In 1943, he received the Nobel Prize in Chemistry for his work on isotopic tracers. He held academic positions in Germany, Denmark, and Sweden and contributed to the Manhattan Project. His techniques revolutionized research in chemistry, biology, and medicine. De Hevesy’s legacy endures in modern isotope methodology and diagnostic imaging.

Walter Gerlach was a German physicist and academic renowned for his role in the Stern–Gerlach experiment of 1922 that demonstrated the quantization of atomic magnetic moments. He served as a professor at several German universities and directed research institutes in Munich and Heidelberg. Gerlach made significant contributions to experimental physics, including work on electron optics and vacuum technology. During World War II, he participated in Germany’s nuclear research programs. After the war, he continued teaching and published on precision measurement techniques. His work helped establish foundational principles in quantum mechanics.

Helen Sawyer Hogg was a pioneering American-Canadian astronomer renowned for her extensive studies of variable stars and their role in understanding stellar evolution. She earned her Ph.D. from the University of Toronto and later became the director of the David Dunlap Observatory. Throughout her career, she published more than 80 research papers and catalogued thousands of variable stars. A passionate educator and communicator, she hosted a weekly astronomy radio program and wrote a syndicated newspaper column. In recognition of her contributions, she was appointed a Companion of the Order of Canada and received honorary doctorates from multiple universities. Her advocacy opened doors for women in the field and left a lasting legacy in observational astronomy.

Raul Renter (1920–1992) was an economist who published research on economic planning and development in Soviet-era Estonia. Alongside his academic work, he was a master-level chess player, winning multiple national tournaments. He contributed articles to economic journals and participated in policy discussions during the post-war period. Renter's dual achievements in scholarship and competitive chess made him a respected figure in Estonia. His legacy endures through his research publications and his impact on the Estonian chess community.

James M. Tanner (1920–2010) was a leading figure in paediatric endocrinology whose work defined modern understanding of child growth. He introduced the Tanner scale, a widely used metric for assessing physical development during puberty. Tanner's research on growth hormone and nutritional factors informed treatment of growth disorders worldwide. He served as professor at the University of Cambridge and led international collaborations in child health research. His contributions have had lasting impact on pediatric medicine and developmental biology.
