George Hickes (1642–1715) was an English divine and scholar renowned for his contributions to the study of early Germanic languages. After ordination as an Anglican minister, he held various parish posts before becoming Dean of Worcester Cathedral. His publication 'Institutiones Grammaticae Anglo-Saxonicae et Moeso-Gothicae' (1689) laid foundations for comparative philology. Hickes also produced important glossaries and manuscripts preserving Old English and Old Norse texts. A staunch non-juror after the Glorious Revolution, he refused to swear allegiance to William and Mary and was deprived of his offices. Despite political exile, he continued scholarly work, influencing later generations of linguists and antiquaries.

Born in 1761, Hübner dedicated his life to the study of Lepidoptera, publishing comprehensive illustrated works such as ‘Tentamen’ and ‘Sammlung Europäischer Schmetterlinge’. His meticulous descriptions and early adoption of binomial nomenclature advanced the scientific understanding of insect biodiversity. Hübner’s collections served as references for future entomologists and naturalists across Europe. He combined artistic illustration skills with scholarly research, making his publications both scientifically valuable and visually striking. Hübner died in 1826, but his taxonomic contributions continue to inform modern entomology.

Isaak August Dorner was born in Darmstadt in 1809 and emerged as a central voice in 19th-century theology. He held professorships at institutions including Tharandt and Berlin. Dorner's multi-volume "History of Protestant Theology" traced doctrinal evolution from early Christianity to modern thought. His works on Christology and ecclesiology earned him recognition across Europe. He engaged in debates on rationalism and revivalism, seeking a mediating theological approach. Dorner influenced students and colleagues with his scholarly rigor and ecumenical outlook. He died in 1884, leaving a lasting impact on Protestant scholarship.

Richard Lodge was born in London in 1855 and pursued studies at University College before entering academia. He became Professor of History at University College, London, and later held the Regius Professorship of Modern History at Oxford. Lodge's research focused on Tudor and Stuart England, as well as the political origins of the American colonies. His works, including "The American Colonies" and essays on constitutional evolution, were widely read. A fellow of the British Academy, he influenced the teaching of history through lectures and popular writings. Lodge's scholarship combined rigorous archival research with engaging narrative. He died in 1936, remembered for his contributions to understanding modern democratic foundations.

Frederick Gowland Hopkins was an English biochemist whose groundbreaking research led to the discovery of vitamins. His identification of accessory food factors revealed the essential role of micronutrients in human health. In recognition of his work, he was awarded the Nobel Prize in Physiology or Medicine in 1929 alongside Christiaan Eijkman. Hopkins served as Professor of Biochemistry at the University of Cambridge, where he mentored future generations of scientists. He also held leadership roles in the Royal Society, helping to advance scientific research policy in the UK. His publications on nutrition and metabolism remained influential for decades. Hopkins' legacy endures in the field of nutritional science and the continuing study of human dietary needs.

George Redmayne Murray was an English physician and biologist celebrated for developing the first effective thyroid hormone replacement therapy. In 1891, he successfully treated a patient with myxedema using sheep thyroid extract, marking a major breakthrough in endocrinology. Murray’s work established the concept of hormone replacement and earned him widespread acclaim in the medical community. He served as Director of the Thyroid Clinic at the Victoria Infirmary in Liverpool, where he refined dosing methods and patient care. Murray published extensively on thyroid disorders and trained many physicians in the emerging field of endocrine therapy. His innovations laid the groundwork for modern treatment of thyroid diseases. Murray’s contributions transformed the prognosis for patients with hypothyroidism worldwide.

Leon Wachholz was a prominent Polish scientist and medical examiner recognized for establishing forensic medicine as a scientific discipline in Poland. As a professor at Jagiellonian University, he authored foundational textbooks on forensic pathology and legal medicine. Wachholz developed innovative methods for crime scene analysis, autopsy procedures, and expert testimony. He helped create standardized practices that improved the accuracy of forensic investigations. Wachholz also trained generations of pathologists and legal experts, influencing medical jurisprudence across Europe. His research bridged the gap between scientific principles and legal requirements in criminal investigations. Wachholz's work laid the cornerstone for modern forensic science in Poland and beyond.

Reginald Punnett was a pioneering English geneticist and statistician who co-founded the field of genetic analysis. After studying under William Bateson, he introduced the Punnett square, a simple diagrammatic tool for predicting inheritance patterns. As Professor of Biology at Cambridge University, he helped launch the Journal of Genetics in 1910, providing a platform for early genetic research. Punnett’s work on Mendelian inheritance clarified the principles governing trait transmission in plants and animals. He collaborated with scientists worldwide to advance the understanding of heredity and population genetics. His textbooks and articles became essential references for geneticists throughout the 20th century. Punnett’s contributions laid the groundwork for modern genetics, influencing research in biology, agriculture, and medicine.

Mary R. Calvert was an American astronomer and author born in 1884. She made significant contributions to the cataloging of star positions and variable stars. Calvert's meticulous work provided valuable data for subsequent generations of astronomers. As an author, she published accessible books and articles that brought the wonders of the night sky to a broader audience. Her dual role bridged the gap between scientific research and public education in astronomy. Calvert's legacy endures in both professional observatory records and popular astronomy writings.

Johannes Heinrich Schultz was born in 1884 in Germany and became a leading figure in psychiatry and psychotherapy. He developed autogenic training, a self-relaxation technique that influenced modern stress-management therapies. Schultz's work integrated physiological and psychological approaches, emphasizing self-regulation of the mind and body. He authored several influential texts on psychotherapy, introducing his methods to an international audience. His techniques laid the groundwork for future developments in behavioral and cognitive therapies. Schultz's legacy is evident in contemporary stress-reduction programs and mind-body wellness practices.

Andrzej Gawroński, born in 1885, was a distinguished Polish linguist and professor. He specialized in comparative linguistics, exploring the relationships between Indo-European languages. Gawroński's scholarly work advanced understanding of historical language development and etymology. He held academic positions at leading universities, mentoring generations of language scholars. His publications remain reference points in Slavic and Indo-European philological studies. Gawroński's rigorous methods helped shape the field of modern linguistics in Poland and beyond.

John S. Paraskevopoulos was born in 1889 in Greece and later became a leading astronomer in South Africa. He served as director of the Union Observatory in Johannesburg, overseeing significant telescopic surveys. Paraskevopoulos made key observations of comets and variable stars in the southern skies. His leadership improved astronomical instruments and research methodologies at the observatory. He published numerous papers that expanded knowledge of celestial objects visible from the southern hemisphere. Paraskevopoulos's work laid foundations for modern astronomy in South Africa and beyond.
