Born in Zurich in 1672, Scheuchzer studied medicine and natural history at his hometown university. He collected and classified fossils across the Alps, advancing understanding of Earth’s ancient life. His 'Herbarium Diluvianum' cataloged fossils he saw as evidence of the biblical Flood, sparking scientific debate. Elected to the Royal Society, he published influential works on Swiss flora, fauna, and geology. Scheuchzer held a professorship in Zurich, mentoring future scientists. He died in 1733, leaving a lasting legacy as one of the first systematic paleontologists.

Leopold Gmelin was a German chemist and professor recognized for his contributions to inorganic chemistry. His multi-volume 'Handbook of Chemistry' systematically cataloged chemical compounds and reactions. Gmelin's work established standards in chemical nomenclature and analytical methods. He held professorships at the universities of Tübingen and Heidelberg, mentoring future scientists. Gmelin also researched uric acid metabolism and metal amine complexes. His legacy endures in the eponymous Gmelin database, a key resource for chemists.

John Tyndall was an Irish-English physicist who made pioneering studies of atmospheric absorption of infrared radiation. His work on the greenhouse effect laid groundwork for modern climate science. Tyndall conducted landmark experiments on diamagnetism and the properties of sound. He was also an accomplished mountaineer, achieving first ascents in the Alps. Tyndall served as a professor at the Royal Institution in London, lecturing to popular audiences. His clear writing and public demonstrations helped popularize science in the Victorian era.

Prafulla Chandra Ray (1861–1944) was an Indian chemist, academic, and entrepreneur. He established the first modern chemical research laboratory in India at Presidency College, Calcutta. Ray made significant contributions to pharmaceutical science by founding Bengal Chemicals & Pharmaceuticals, India’s first drug manufacturing company. His work helped lay the foundation for chemical education and industry in India. An ardent social reformer, he also advocated for national self-reliance in science and education. Ray's legacy endures in India’s scientific institutions and continued pharmaceutical advancements.

Irving Babbitt (1865–1933) was an American academic and literary critic best known for founding the New Humanism school of thought in the early 20th century. He taught at Harvard University, where his rigorous analysis of literature emphasized moral and ethical dimensions in texts. Babbitt's critiques focused on Romanticism and materialism, advocating a return to classical humanist values. His major works include 'Literature and the Higher Life' and 'Democratic Education'. Through his writing and teaching, Babbitt influenced debates on culture, ethics, and the purpose of education in modern society. His intellectual legacy continues to inform discussions on humanistic criticism and liberal education.

Marianne Weber (1870–1954) was a German sociologist, political activist, and advocate for women’s suffrage. She earned a doctorate in law, a rarity for women of her era, and published influential studies on family law and women’s legal status. Weber collaborated closely with her husband, sociologist Max Weber, editing his writings and promoting his work after his death. Her own scholarship, including 'The Woman in the Nineteenth Century', addressed gender roles, marriage, and social reform. As a suffragist, she campaigned for women’s voting rights in Germany and co-founded organizations to support female professionals. Marianne Weber's work laid important groundwork for modern feminist thought and sociological research on gender.

Pingali Venkayya (1876–1963) was an Indian geologist, scholar, and independence activist who designed the flag that became the national emblem of India. He presented his tricolor concept to Mahatma Gandhi in 1921, incorporating saffron, white, and green bands with the spinning wheel (charkha) symbol. His design came to represent courage, purity, and progress, and was officially adopted by the Constituent Assembly in 1947. Besides his work on the flag, Venkayya contributed to geological surveys and agricultural research under British rule. He also lectured extensively to promote scientific education in rural India. Venkayya's enduring legacy is India’s flag, which continues to unite a diverse nation under its vibrant colors.

Oskar Anderson (1887–1960) was a mathematician and statistician who made significant contributions to correlation theory and time series analysis. Born in the Russian Empire, he later worked in Germany and Bulgaria, influencing statistical research in Europe. Anderson introduced innovative methods for analyzing economic and meteorological data using stochastic processes. He taught at the University of Munich and held positions at various scientific institutes. His publications remain fundamental references in the study of statistical theory and applications. Anderson's work helped shape modern quantitative methods across multiple disciplines.

Viktor Zhirmunsky (1891–1971) was a pioneering Russian linguist and historian. He specialized in the historical development of Slavic and Germanic languages and the study of literary traditions. He held academic positions at the University of Leningrad and the Soviet Academy of Sciences. Zhirmunsky introduced comparative methods to literary analysis and historical linguistics in Soviet scholarship. His research on medieval literature and folklore shaped modern understanding of Slavic cultural history. He is remembered as a foundational figure in 20th-century linguistic and literary studies.

Bertha Lutz (1894–1976) was a Brazilian zoologist and one of the foremost leaders of the feminist movement in Brazil. She studied at renowned institutions abroad, contributing important research in herpetology. In 1919 she co-founded the Brazilian Federation for the Advancement of Women and campaigned tirelessly for women's voting rights, achieved in 1932. Lutz served as a delegate to international women's conferences and represented Brazil at the League of Nations. Her dual legacy in science and activism made her a pioneering figure in both fields.

Born in 1902, Mina Rees earned her Ph.D. in mathematics from Bryn Mawr College. She joined the City University of New York and rose to become dean of its Graduate School. Rees was instrumental in securing federal support for scientific research and the development of early computing programs. She served as president of the American Association for the Advancement of Science, advocating for women in STEM. Her leadership helped shape modern graduate education and national research policy. She is remembered for her contributions to mathematics and science administration.
