He accurately predicted events such as the Great Fire of London and various military outcomes. His diaries and casebooks provide valuable accounts of 17th-century social and political life. Lilly continued to publish annual almanacs until his death in 1681, influencing generations of astrologers.

Anna Atkins was an English scientist and artist who fused her passion for botany with emerging photographic techniques. In 1843, she published 'Photographs of British Algae: Cyanotype Impressions', the first book to use actual photographic prints to illustrate scientific specimens. Working with the cyanotype process developed by John Herschel, Atkins produced detailed images of seaweed and algae that combined scientific accuracy with aesthetic beauty. Her work laid the groundwork for scientific photography and remains a landmark in the history of both photography and natural history. Atkins's legacy endures in botanical art and documentary photography.

Gérard Paul Deshayes was a pioneering French naturalist whose research in conchology and geology advanced the understanding of Earth's history. He conducted detailed examinations of fossil mollusks, establishing correlations between shell species and geological strata. Deshayes published seminal works including 'Traité Élémentaire de Conchyliologie' and 'Description des Animaux Sans Vertèbres', which became standard references in paleontology. His stratigraphic studies in France and abroad helped shape the nascent field of biostratigraphy. Deshayes's meticulous approach to classification and his paleontological insights left a lasting imprint on geology and evolutionary biology.

Adolf Bötticher was a German art historian and curator whose work focused on the documentation and preservation of architectural heritage. He conducted extensive surveys of castles, churches, and medieval structures across Germany and Eastern Europe. His publications, such as 'Die historische Bauforschung' and detailed travel reports, provided invaluable records of monuments that later suffered damage or destruction. Bötticher's systematic approach to art history and his advocacy for conservation influenced the development of cultural heritage management in the late 19th century. His meticulous illustrations and descriptions remain reference points for scholars and restoration experts.

Adolf Otto Reinhold Windaus was born in 1876 and became a leading figure in organic chemistry. He conducted groundbreaking work on the structure and function of sterols, elucidating the molecular basis of cholesterol. Windaus's research into the conversion of 7-dehydrocholesterol to vitamin D earned him the Nobel Prize in Chemistry in 1928. As a professor at the University of Göttingen, he mentored a generation of chemists and expanded the field of biochemical research. His discoveries had profound implications for nutrition and medicine, particularly in understanding bone health. Windaus continued his academic career through tumultuous historical periods in Germany, maintaining scientific excellence. He died on June 9, 1959, leaving a lasting legacy in chemistry.

Camille Guérin was born in 1872 in Poitiers, France, and trained as a veterinarian before turning to bacteriology. Collaborating with Albert Calmette at the Pasteur Institute, he co-developed the Bacillus Calmette–Guérin (BCG) vaccine, a breakthrough in tuberculosis prevention. His work involved refining the attenuation of Mycobacterium bovis and ensuring vaccine safety and efficacy. Guérin's contributions had a global impact, drastically reducing TB mortality rates worldwide. He published extensively on immunology and mentored future leaders in the field. Guérin remained active in research throughout his career, influencing vaccine development for other diseases. He passed away on June 9, 1961, leaving a legacy of innovation in infectious disease control.

George Wells Beadle (1903–1989) was a pioneering American geneticist whose work laid the foundation for molecular biology. Alongside Edward Tatum, he demonstrated that genes act by regulating specific enzymes, formulating the 'one gene, one enzyme' hypothesis. Their groundbreaking experiments with the bread mold Neurospora crassa earned them the Nobel Prize in Physiology or Medicine in 1958. Beadle later served as president of the University of Chicago, promoting scientific education and research. He also advised national science policy, influencing funding and direction of genetic studies. Beadle's legacy endures in modern genetics and biotechnology, where his insights continue to inform the understanding of gene function.

Jan Tinbergen was a pioneering Dutch economist who shared the first Nobel Prize in Economic Sciences in 1969. He is known for developing the first macroeconometric models to quantify economic policies. Born in The Hague in 1903, he studied physics and economics before launching his academic career. Tinbergen taught at the Netherlands School of Economics (now Erasmus University Rotterdam) for decades. His work laid the foundation for modern econometric analysis and welfare economics. He remained active in research and advised international organizations on economic planning.

Stanley Knowles was a prominent Canadian politician and labour studies professor who championed social welfare reforms. Born in Buffalo, New York in 1908, he moved to Canada and joined the Co-operative Commonwealth Federation. Knowles served as the Member of Parliament for Winnipeg North for 33 years as a member of the New Democratic Party. He played a key role in establishing Canada's Old Age Security pension and family allowance programs. Known for his eloquent speeches and dedication to working-class Canadians, he became a respected voice in Ottawa. After retiring from politics, he continued to teach and write on labour issues until his death in 1997.

Lois Mailou Jones was an influential African-American painter and educator whose career spanned over seven decades. Born in Boston in 1905, she studied at the School of the Museum of Fine Arts and traveled extensively in Europe and Haiti. Her early works were associated with the Harlem Renaissance, while later pieces incorporated African and Caribbean motifs. Jones taught at Howard University for four decades, mentoring generations of Black artists. Her vibrant use of color and innovative style made her a pioneering figure in American modernism. She exhibited internationally and received numerous awards before her death in 1998.

Jacob Lawrence was a celebrated American painter whose work captured the African-American experience. Born in Atlantic City in 1917 and raised in Harlem, he gained prominence with his Migration Series in 1940.
