Robert de Sorbon (1201–1274) was a French theologian and royal chaplain to King Louis IX. He established the Collège de Sorbonne in 1257 as a residence for poor theology students. Under his guidance, the Sorbonne became a premier center of theological study in Europe. He authored several important theological works, including commentaries on Peter Lombard's Sentences. His commitment to education contributed to the growth and reputation of the University of Paris. Today, the Sorbonne name remains synonymous with academic excellence across Europe.

Salimbene di Adam (1221–1290) was an Italian Franciscan friar and prolific writer. He traveled extensively across Italy, Germany, and France as part of his religious duties. His personal chronicles, the 'Chronica', record events ranging from local disputes to papal politics. Salimbene's narratives are noted for their vivid anecdotes, sharp observations, and candid opinions. His works remain key sources for historians studying 13th-century Europe. Through his writings, Salimbene offers a unique firsthand perspective on the social and religious life of his time.

Claude Gaspard Bachet de Méziriac (1581–1638) was a French mathematician renowned for his contributions to number theory. He collected and translated ancient Greek mathematical works, including those of Diophantus. His book 'Problèmes plaisants et délectables' popularized mathematical puzzles across Europe. Bachet’s work on Diophantine equations influenced later mathematicians, including Fermat. Apart from mathematics, he composed Latin and French poetry reflecting humanist interests. His scholarship bridged the Renaissance and early modern periods in European mathematics.

Nicolaes Tulp (1593–1674) was a prominent Dutch anatomist and civic leader in Amsterdam. He served as the city’s mayor multiple times, overseeing public health and administration. Tulp gained fame for his detailed anatomical demonstrations and published works on medicine. In 1632, he appeared in Rembrandt’s 'The Anatomy Lesson of Dr. Nicolaes Tulp', immortalizing his legacy. His publications on anatomy became essential references for medical students and scholars. Tulp’s blend of scientific expertise and political influence exemplified the Dutch Golden Age.

Ferdinand Verbiest (1623–1688) was a Flemish Jesuit missionary renowned for his scientific achievements in China. Invited by Emperor Kangxi, he supervised the imperial observatory and reformed the Chinese calendar. Verbiest designed and built precision astronomical instruments, improving celestial observations. His work on thermometers and hydraulic models demonstrated advanced engineering skills. As a cultural ambassador, he translated European scientific texts into Chinese and vice versa. Verbiest’s fusion of science and faith exemplifies the Jesuit mission of knowledge exchange between continents.

Johann Andreas Segner (1704–1777) was a German scholar who made significant contributions to mathematics and physics. He served as a professor at the University of Jena and later at the University of Göttingen. Segner’s studies in hydrostatics led to the invention of the Segner wheel, an early reactive turbine. He published widely on mechanics, optics, and medical science, showcasing his interdisciplinary interests. His work influenced later developments in fluid dynamics and engineering. Segner’s legacy lives on through his students and the continued study of his pioneering inventions.

Born in 1796, Joseph Bonomi the Younger was the son of a prominent Italian sculptor and trained under his father's tutelage. He joined the second expedition of the Franco-Tuscan archaeological mission to Egypt, where he made pioneering architectural drawings. Bonomi's work documented monuments and tombs at Thebes, contributing to the early understanding of Egyptian architecture. Upon returning to London, he became a sought-after sculptor and exhibited at the Royal Academy, blending archaeological insight with artistry. His published memoirs and sketches provided critical resources for both scholars and artists until his death in 1878.

Born in 1837, Francis Wayland Parker revolutionized American education by emphasizing experiential learning over rote memorization. He served as principal of Quincy Grammar School in Massachusetts, where he implemented his innovative teaching practices. Parker's methods encouraged student curiosity, discussion, and critical thinking, laying the foundation for modern progressive education. He later directed the Cook County Normal School in Chicago, training teachers in his philosophies. His publications and leadership influenced generations of educators before his death in 1902.

Born in 1850 in Germany, Hermann von Ihering emigrated to Brazil and dedicated his life to studying its diverse wildlife. He served as director of the Museu Paulista in São Paulo, where he organized extensive zoological collections. Ihering conducted field research throughout Brazil, describing numerous new species of mollusks and insects. He published influential papers that advanced understanding of Neotropical ecosystems. Ihering's efforts helped establish Brazil as a center for zoological research before his death in 1930.

Born in 1852, Hermann Emil Fischer studied under August Wilhelm von Hofmann and later led the Chemical Institute at the University of Berlin. He developed the Fischer esterification method and elucidated the structures of glucose and other sugars. Fischer's work on purines and nucleosides earned him the 1902 Nobel Prize in Chemistry. He also introduced the Fischer projection, a critical tool for representing stereochemistry in organic molecules. His pioneering research transformed the field of biochemistry before his death in 1919.

Born in Idvor, Serbia, in 1858, Mihajlo Pupin emigrated to the United States as a teenager and overcame poverty to pursue his education. He studied and taught at Columbia University, where he conducted groundbreaking research in electrical engineering. Pupin patented the Pupin coil in 1899, a device that extended the range of telephone transmissions, transforming global communications. His investigations into X-ray imaging led to improvements in medical diagnostics. He served as president of the American Institute of Electrical Engineers and was elected to the National Academy of Sciences. His memoir, "From Immigrant to Inventor," won the Pulitzer Prize for Biography in 1924. Pupin advocated for science education and Yugoslav-American relations until his death in 1935.

Born in Frankfurt am Main in 1873, Karl Schwarzschild studied physics and astronomy at the University of Erlangen and Munich. He completed his doctorate under Arnold Sommerfeld, working on spectroscopic studies. While serving on the Russian front in World War I, Schwarzschild found the exact solution to Einstein's field equations in 1915. The Schwarzschild metric describes the gravitational field outside a spherical mass, defining the concept of the event horizon. His contributions extended to stellar photometry and differential equations in theoretical physics. Weak health due to an autoimmune disease led to his death in 1916. His work remains fundamental to modern astrophysics and black hole research.
