Tiberius Hemsterhuis was born in Amsterdam in 1685 and became a leading figure in classical philology. He specialized in ancient Greek, publishing influential grammars and commentaries on classical authors. His lectures at Leiden University attracted students from across Europe and advanced the study of Greek language. Hemsterhuis's meticulous textual analysis set new standards for classical scholarship. He remained a respected critic and editor until his death in 1766.

Born in 1823, Friedrich von Esmarch studied medicine at the Universities of Göttingen and Berlin. He served as professor of surgery at the University of Kiel and later at the University of Berlin. Esmarch introduced the eponymous Esmarch bandage to control bleeding and develop first aid techniques. He wrote influential surgical textbooks that became standard references across Europe. In 1881, he founded the first voluntary ambulance service in Germany. His methods greatly improved battlefield medical care and civilian emergency response. Esmarch's contributions laid the foundation for modern first responder and trauma care systems. He died in 1908, remembered as a pioneer in surgical education and emergency medicine.

Born in 1829 into the scholarly Schlagintweit family, Adolf embarked on exploratory missions at a young age. He, along with his brothers, conducted botanical and geological surveys in the Alps before venturing to India. Between 1854 and 1856, he traveled extensively in the Himalayas and Karakoram, collecting thousands of plant specimens. His detailed reports and illustrations introduced many new species to European science. Schlagintweit's research expanded knowledge of Asian flora and contributed to the mapping of remote regions. During an expedition in Kashgar, he was tragically executed in 1857 under unclear circumstances. Despite his untimely death, his collections continue to be studied by botanists worldwide. His work remains a testament to the spirit of 19th-century scientific exploration.

Born in 1839 in Maine, John Knowles Paine was the first American-born composer to gain international recognition. He studied in Germany under the tutelage of renowned composers before returning to Boston. In 1862, Paine became the first professor of music at Harvard University, establishing the institution's music program. His compositions include a symphony, organ works, and choral music that blended European forms with American themes. Paine served as the organist at Boston's Hollis Street Church, earning acclaim for his performances. He played a key role in founding the Boston Symphony Orchestra in 1881. His teaching influenced generations of American musicians and elevated the status of music education in the U.S. Paine died in 1906, leaving a legacy as a pioneer of American classical music.

Vladimir Andreevich Steklov (1864–1926) was a Russian mathematician and physicist who made significant contributions to mathematical physics and analysis. He formulated the Steklov eigenvalue problem and advanced the theory of integral equations and boundary value problems. His work laid the groundwork for later developments in potential theory. Steklov's research influenced both pure and applied mathematics, and his name remains associated with several fundamental concepts. His publications and lectures inspired a generation of mathematicians in early 20th-century Russia.

S. P. L. Sørensen (1868–1939) was a Danish chemist who laid the foundations for modern biochemistry. While working at the Carlsberg Laboratory, he developed the pH scale as a quantitative measure of acidity and alkalinity. His precise analytical methods revolutionized protein and enzyme research. Sørensen served as a professor at the University of Copenhagen, mentoring the next generation of chemists. His introduction of pH remains a cornerstone of chemical and biological sciences more than a century later.

Joseph Strauss (1870–1938) was an American structural engineer and bridge designer. As chief engineer of the Golden Gate Bridge, he oversaw its design and construction, leading to the completion of the landmark suspension bridge in 1937. Strauss patented innovative bridge-building techniques and advocated for worker safety by introducing safety nets that saved lives during construction. His career included projects across the United States, demonstrating expertise in long-span bridge design. A graduate of the University of Cincinnati, he combined practical problem solving with visionary engineering. Strauss's work on the Golden Gate Bridge cemented his reputation as one of America's foremost engineers.

John B. Watson (1879–1958) was an American psychologist who pioneered the behaviorist approach in psychology. His 1913 publication "Psychology as the Behaviorist Views It" rejected introspection in favor of observable behavior. Watson conducted experiments on conditioning and learning, demonstrating that behavior could be shaped by environmental stimuli. He led the psychology department at Johns Hopkins University before moving to the advertising industry, where he applied behavioral principles to marketing strategies. Watson's work laid the foundation for later behaviorists and influenced fields ranging from education to psychotherapy. His emphasis on scientific methods transformed psychology into an empirical discipline.

Lloyd Loar was a visionary American sound engineer whose designs revolutionized stringed instruments in the early 20th century. As a designer for the Gibson Mandolin-Guitar Manufacturing Company, he introduced f-holes and arched tops to mandolins and guitars, dramatically enhancing their tonal quality. Loar’s signature L-5 guitar remains a benchmark in electric and acoustic instrument design. His research into acoustics and instrument construction laid the foundation for modern luthiery. After leaving Gibson, he continued experimenting with acoustical principles and held several patents related to sound reproduction. His innovations continue to influence instrument makers and musicians worldwide.

Born in Delhi in 1920, Said relocated to Karachi after the partition of India and earned his medical degree, becoming a leading authority in Unani medicine. He founded the Hamdard Foundation to promote traditional healthcare, education, and social welfare across Pakistan. Serving as a senator and briefly as the 20th Governor of Sindh in 1993–1994, he was also known for his advocacy of peace and interfaith dialogue. Said authored numerous books on medicine, literature, and Sufism, reflecting his diverse intellectual interests. His philanthropic initiatives included hospitals, universities, and charitable clinics serving millions. He was assassinated in 1998, leaving behind a legacy of scholarship, service, and national development.

Har Gobind Khorana was born in 1922 in Raipur, British India, and later became a naturalized American citizen. His groundbreaking research on nucleic acids led to the deciphering of the genetic code and the first synthesis of oligonucleotides. In 1968, he shared the Nobel Prize with Robert W. Holley and Marshall W. Nirenberg. Khorana's work laid the foundation for modern genetic engineering and biotechnology. He held professorships at the University of Wisconsin–Madison and the Massachusetts Institute of Technology. Throughout his career, he authored hundreds of papers and mentored many leading scientists.

Born in 1936, Veselica served as a professor of economics and became a prominent critic of the Yugoslav government. During the Croatian Spring in 1971 he advocated for greater autonomy and was arrested and imprisoned for his dissent. His writings and speeches made him a symbol of the fight for Croatian human rights. After his release, he co-founded the Croatian Democratic Party and played a key role in Croatia's movement toward independence. He returned to academia, mentoring a new generation of scholars before his death in 2017.
