Étienne Louis Geoffroy was born in Paris and trained as a pharmacist under his father. He developed a deep interest in insects and published "Histoire abrégée des Insectes" in 1762, one of the earliest systematic works on entomology. Geoffroy's meticulous descriptions and illustrations helped standardize the classification of European insects. He served as an apothecary to King Louis XV and lectured on natural history. His work influenced Carolus Linnaeus and other contemporary naturalists. Geoffroy's collections and writings laid the groundwork for modern entomological studies. He continued to practice pharmacy and study insects until his death in 1810.

Christian Gmelin was born into the renowned Gmelin family of scientists in Tübingen. He studied chemistry and pharmacy at the University of Tübingen, later becoming a professor there. Gmelin conducted significant research on the composition of mineral springs and the properties of organic acids. He published detailed analyses of natural waters and contributed to early studies of lactic and citric acids. His work helped advance the understanding of chemical composition in geological and biological contexts. Gmelin also mentored a generation of German chemists during his academic career. He remained active in teaching and research until his death in 1860.

Arthur Nikisch was born in Sopron, Hungary in 1855 and studied music at the Vienna Conservatory. He rose to prominence as the conductor of the Leipzig Gewandhaus Orchestra and later led the Berlin Philharmonic. Nikisch was celebrated for his expressive baton technique and deep musical insight, shaping the performance style of late Romantic repertoire. He also taught conducting at the Leipzig Conservatory, mentoring a generation of future maestros. His international tours with ensembles introduced live orchestral music to global audiences. Nikisch's influence endured through his recordings and his students' contributions to 20th-century conducting.

Arthur Harden was born in 1865 in Manchester and studied at the University of Manchester and Leipzig University. His pioneering research on yeast fermentation elucidated the role of coenzymes in alcoholic fermentation. In 1929, he shared the Nobel Prize in Chemistry with Hans von Euler-Chelpin for their investigations into the fermentation of sugars and enzymes. Harden held professorships at the University of Liverpool and the Royal Institution in London, mentoring many future scientists. He published extensively on enzymology, laying the foundations for modern biochemistry. Harden served as Secretary and President of the Biochemical Society, shaping the field's professional community. He died in 1940, leaving a lasting impact on metabolic biochemistry.

Ralph Vaughan Williams was born in 1872 in Down Ampney, Gloucestershire, England, into a musical family. He studied at the Royal College of Music under Hubert Parry and Charles Villiers Stanford. His compositions, including 'The Lark Ascending' and the 'Fantasia on a Theme by Thomas Tallis,' drew inspiration from English folk songs and modal harmony. Vaughan Williams served as a professor of music at the University of Oxford, influencing generations of British composers. He also collected and edited folk song anthologies, preserving cultural heritage. His nine symphonies charted the evolution of his style, from lyrical romanticism to modernist exploration. Vaughan Williams died in 1958, leaving a lasting legacy in British and global music.

Anthony F. DePalma (1904–2005) was a pioneering orthopedic surgeon and respected professor at the University of Rochester. He authored influential textbooks on joint replacement and spinal surgery, shaping modern orthopedic practice. DePalma’s research on prosthetic design helped improve patient outcomes and mobility. A dedicated mentor, he trained generations of surgeons and led key professional societies. His contributions to surgical technique and medical education left a lasting impact on the field.

Malcolm Renfrew was an American chemist who made significant contributions to the development of fluoropolymers and fluorine chemistry. As a professor at the University of Idaho, he helped refine the industrial synthesis processes for Teflon, influencing materials science and engineering. Renfrew published extensively on polymer chemistry and served as department chair, mentoring generations of students. His work earned him recognition from professional societies, including the American Chemical Society. Well into his later years, he remained an active scholar and lecturer, leaving a lasting legacy in polymer research.

Muhammad Shamsul Huq was a prominent Bangladeshi academic and statesman. He served as Bangladesh's Foreign Minister from 1986 to 1991, representing the country at the United Nations and strengthening diplomatic ties. A professor at the University of Dhaka, he published extensively on education policy and South Asian studies. Huq also held government roles in education, contributing to curriculum reform and adult literacy programs. His dual legacy as a scholar and diplomat earned him respect in both academia and governance.

Alice Chetwynd Ley was an English author and educator. She published both fiction and non-fiction works, demonstrating versatility across genres. Ley's writing was noted for its engaging storytelling and clear prose. As an educator, she developed literature and writing curricula for students and adult learners. Through lectures and publications, she championed the importance of literary education and inspired future writers.

John E. Hodge was an American chemist whose pioneering research in carbohydrate chemistry advanced understanding of sugar reactions and polymer formation. Working with the U.S. Department of Agriculture, he elucidated key mechanisms in the Maillard reaction fundamental to food science. Hodge published influential papers that shaped studies in organic and polymer chemistry. As a mentor, he advocated for minority scientists and fostered academic collaborations. His work earned recognition from the American Chemical Society and left a lasting impact on scientific research.

Denis Lazure was a Canadian psychiatrist and academic who pioneered community-based mental health services in Quebec.
