Johann Bernoulli was a member of the famous Bernoulli family of mathematicians, born in Basel in 1667. He studied theology but quickly shifted his focus to mathematics under the mentorship of Jacob Bernoulli. Johann became a leading figure in the early development of differential and integral calculus. He published influential works on series, probability, and curves, and his correspondence with other scientists spread new mathematical ideas across Europe. Bernoulli held a professorship at the University of Groningen and later at the University of Basel. His disputes and collaborations with his brother Jacob and with Leibniz were central to mathematical debates of the time. Johann’s clear teaching style and numerous textbooks inspired generations of mathematicians. He died in 1748, leaving behind a lasting legacy in mathematical analysis.

William Hyde Wollaston was born in 1766 in East Dereham, England, and became a pioneering scientist. He studied medicine in Cambridge but devoted his career to chemistry and physics. In 1803, Wollaston discovered the metals palladium and rhodium, expanding the periodic table. He developed a method for refining platinum and designed the first camera lucida, aiding artists and scientists in accurate drawing. Wollaston’s work in spectroscopy provided early evidence for dark lines in the solar spectrum, a foundation for later astronomical spectroscopy. He also conducted research on the composition of meteorites and sunlight’s refrangibility. His scientific achievements earned him Fellowship of the Royal Society and the prestigious Copley Medal. He died in 1828, remembered as an innovative experimentalist whose work shaped modern chemistry.

Born in 1835 in Denmark, Hjalmar Kiærskou studied at the University of Copenhagen and later became a professor at the Royal Veterinary and Agricultural University. He specialized in phanerogamic botany, producing detailed monographs on genera such as Rubus. As director of the Copenhagen Botanical Garden, he expanded research collections and mentored future botanists. His meticulous classification work advanced the understanding of plant taxonomy in the late 19th century. Kiærskou's legacy endures through species names and foundational publications that remain references for botanists today. He passed away in 1900, remembered for his scholarly rigor and dedication to the natural sciences.

Born in 1844 in Grahamstown, South Africa, James Henry Greathead moved to England to study at the Royal College of Science. He refined Peter Barlow's tunneling shield design and developed the cylindrical Greathead Shield, enabling safer underground work. His innovation was instrumental in building the City & South London Railway, the world's first deep-level electric tube line. Greathead served as engineer on several major metropolitan projects, revolutionizing urban tunneling techniques. His contributions laid the groundwork for modern subway and underground construction around the globe. He died in 1896, leaving a legacy as a pioneer of civil engineering.

Alexander Fleming was a Scottish biologist and pharmacologist born in 1881. In 1928, he made the groundbreaking discovery of penicillin, the world's first antibiotic. His work revolutionized medicine by introducing effective treatments for bacterial infections. Fleming shared the 1945 Nobel Prize in Physiology or Medicine for this discovery. He also made important contributions to immunology and bacteriology through extensive research. His legacy lives on in modern medicine and the countless lives saved by antibiotics.

Constance Georgina Adams was a South African botanist born in 1883. She specialized in cataloging and classifying indigenous plant species. Adams conducted extensive fieldwork across diverse South African ecosystems. Her meticulous collections enriched botanical gardens and herbariums. She published important papers on regional flora taxonomy and conservation. Adams' work laid the foundation for future botanical research in South Africa.

Scott Nearing was an influential American economist and educator born in 1883. He taught at the University of Pennsylvania and New York University before leaving academia. Nearing authored widely used textbooks on economic theory and became a leading pacifist activist. He was a prominent figure in the social reform movements of the early 20th century. Later in life, he and his wife practiced homesteading in Vermont and Maine. Nearing's writings on economics, civil liberties, and simple living continue to inspire activists.

Born in Manchester, England, Cecil Howard Green pursued a career in geophysics before emigrating to the United States. In 1951, he co-founded Texas Instruments, pioneering advances in semiconductor technology and consumer electronics. Under his leadership, the company introduced the first silicon transistor and expanded into calculator and instrumentation markets. Green was also a dedicated philanthropist, supporting education and research through foundations and university endowments. He held degrees from MIT and Rice University and received numerous honors for his scientific and business achievements. Green's legacy endures in both the academic world and high-tech industry.

Maria Ludwika Bernhard studied classical archaeology and specialized in ancient Mediterranean civilizations. During World War II, she joined the Polish resistance, using her expertise to document and safeguard artworks and artifacts threatened by occupation forces. Bernhard participated in clandestine operations to smuggle cultural treasures to safer locations. After the war, she resumed her academic career, teaching at the University of Poznań and publishing research on classical art. She advocated for the preservation of Poland's archaeological sites and mentored future scholars. Her dual legacy as a scientist and patriot earned her recognition both in academia and national history.

Richard Hofstadter was born in 1916 in Buffalo, New York. He earned his Ph.D. at Columbia University and became a professor at the University of California, Berkeley. Hofstadter wrote landmark books such as "The American Political Tradition" and "Anti-Intellectualism in American Life," winning two Pulitzer Prizes. His work examined the complexities of American political thought, populism, and social movements. Hofstadter's clear prose and analytical depth made him a leading figure in mid-20th-century historical scholarship. He also held the presidency of the American Historical Association, influencing the direction of the field. Hofstadter died in 1970, leaving a profound impact on the study of American history and political ideas.

He taught East Asian studies at the University of California, Irvine and became a respected political scientist. His book 'Blowback: The Costs and Consequences of American Empire' introduced the concept of unintended consequences of foreign interventions. Johnson's writing critically examined globalization, military strategy, and economic policy. He influenced debates on imperialism and reshaped public understanding of U.S. global power. His work remained influential until his death in 2010.

Mukhu Aliyev (born 1940) is a Russian philologist who transitioned into politics and became the second President of Dagestan. He began his career as a university lecturer and researcher in linguistics, publishing on regional languages and folklore.
