Born in 1513 in England, and educated at Oxford University and the University of Salamanca. Mastered Spanish, Arabic, and Hebrew during his studies abroad. Served as English ambassador to Spain, Venice, and other European courts. Translated classical works and penned treatises on political theory and history. Advocated for educational reform and linguistic scholarship in England. Played a key role in Tudor diplomacy, negotiating alliances and agreements. His writings enriched English Renaissance humanism and cross-cultural understanding. Died in 1577, remembered for bridging intellectual and diplomatic spheres.

Étienne Louis Geoffroy, born in 1725, was a French pharmacist with a deep passion for natural history. He published one of the first systematic catalogues of European insects, laying groundwork for modern entomology. Geoffroy's work included detailed descriptions and classifications that influenced later taxonomists such as Linnaeus. He served as a municipal apothecary in Paris, balancing his medical practice with scientific research. His publications, notably 'Histoire abrégée des Insectes', became reference works for scholars across Europe. Geoffroy's contributions bridged medicine and biology, establishing him as a leading figure in the Enlightenment's scientific community.

George Stephenson was an English engineer born in 1781 who revolutionized transportation with his work on steam locomotives. He built the first successful steam-powered railway locomotive, 'Locomotion No. 1', and later developed the famous 'Rocket' for the Rainhill Trials of 1829. Stephenson's designs set the standard for locomotive engineering and enabled the rapid expansion of rail networks. He also contributed to the construction of early railway lines, including the Stockton and Darlington Railway and the Liverpool and Manchester Railway. His advocacy for safety features, such as the steam whistle and improved braking systems, enhanced operational reliability. Stephenson's innovations laid the foundation for modern railway transport and earned him international recognition before his death in 1848.

Albert Gallatin was born in Geneva in 1761 and emigrated to the United States in 1780. He became the longest-serving U.S. Secretary of the Treasury (1801–1814), guiding American finances under Presidents Jefferson and Madison. Gallatin reduced national debt, advocated for infrastructure improvements like roads and canals, and supported the Lewis and Clark expedition. A polymath, he conducted ethnological and linguistic studies of Native American tribes, publishing influential works on their languages and cultures. Gallatin later served as U.S. Minister to Great Britain, promoting diplomatic relations after the War of 1812. His dual legacy as a fiscal visionary and pioneering social scientist marks him as a key figure in early American history.

Sakuma Shōzan (1811–1864) was a Japanese scholar of Confucianism and visionary political thinker during the Bakumatsu period. He embraced Western science and technology, introducing modern military techniques and naval studies to Japan. Promoting the motto 'Eastern ethics, Western science', he influenced key figures who led the Meiji Restoration. He served as an advisor to regional lords, advocating for national unity and reform. His assassination in 1864 by anti-foreign samurai made him a martyr for Japan's modernization, leaving a lasting intellectual legacy.

William Jackson Hooker (1785–1865) was an influential English botanist and academic who transformed Kew Gardens into a world-leading center for botanical research. He conducted extensive plant explorations across Europe, Asia, and America, cataloguing thousands of species. As professor of botany at Glasgow and later director at Kew, he published seminal works such as 'Flora Scotica' and 'Exotic Flora'. His efforts helped standardize plant classification and inspired future generations of botanists, including his son Sir Joseph Dalton Hooker. Hooker's contributions laid important foundations for modern plant taxonomy and horticulture.

Adolf Erik Nordenskiöld (1832–1901) was a Finnish-Swedish botanist, geologist, mineralogist, and Arctic explorer. He is best known for leading the Vega expedition (1878–1879), the first voyage to circumnavigate Eurasia via the Northeast Passage. Nordenskiöld conducted groundbreaking scientific research on Arctic geology and flora, collecting vital data and specimens. His scholarly publications advanced understanding of mineralogy and polar science. Honored by scientific societies across Europe, his achievements bridged exploration and academia, inspiring future polar research and navigation.

John Philip Holland (1840–1914) was an Irish-American engineer and inventor who pioneered modern submarine technology. He designed and built the prototype HMS Holland 1 and later the USS Holland (SS-1), commissioned by the U.S. Navy in 1900. Holland's vessels featured internal combustion engines for surface running and electric motors for submerged travel, setting standards for future submarines. His work overcame early technical challenges and proved the military viability of undersea warfare. Holland's innovations laid the groundwork for naval engineering and shaped the future of submarine fleets worldwide.

Friedrich Schottky made foundational contributions to the theory of complex functions and Riemann surfaces. He introduced the concept of Schottky groups, which are central to modern algebraic geometry. His work on theta functions and abelian varieties advanced the understanding of multi-dimensional complex tori. Schottky held academic positions at several German universities, mentoring future generations of mathematicians. His research laid groundwork for later developments in string theory and mathematical physics. Schottky’s insights continue to influence contemporary studies in geometry and analysis.

Jacques Pellegrin was a renowned French zoologist born in 1873. He specialized in ichthyology and herpetology, describing hundreds of new species during his tenure at the Muséum National d’Histoire Naturelle in Paris. Pellegrin’s meticulous classification methods and detailed publications became foundational references in zoology. He collaborated with leading naturalists of his time and contributed to the expansion of museum collections across Europe. His legacy endures in the scientific names of many aquatic species he first documented.

James B. Sumner was born in 1887 in Canton, Massachusetts, and revolutionized biochemistry by demonstrating that enzymes are proteins. In 1926, he successfully crystallized urease, a breakthrough that earned him half of the Nobel Prize in Chemistry in 1946. His work laid the groundwork for modern enzymology and advanced the understanding of protein structure. Sumner spent much of his career at Cornell University, mentoring students and publishing influential research. His discoveries remain fundamental to biochemistry and molecular biology.

Esther Forbes was born in 1891 in Worcester, Massachusetts, and became an esteemed historian and writer. Her meticulously researched 'Paul Revere and the World He Lived In' won the Pulitzer Prize for History in 1944. That same year, her novel 'Johnny Tremain' earned the Newbery Medal, becoming a classic of children’s literature. Forbes brought early American history to life with engaging narrative and scholarly precision. Her dual talent for academic research and storytelling left an enduring mark on historical writing.
