He is remembered for restoring order after a period of tyranny and for fostering cultural and administrative developments in early 16th-century Joseon.

Petrus Apianus (1495–1557) was a German Renaissance mathematician, astronomer, and cartographer who published the influential 'Astronomicum Caesareum' with detailed star charts. He developed the Apian projection for maps and created popular almanacs that guided navigators and scholars. Appointed a court mathematician by Emperor Charles V, he lectured at the University of Ingolstadt and contributed to the spread of scientific knowledge. His work bridged medieval traditions and emerging astronomical science, influencing later instrument makers. Apianus's legacy endures in the history of cartography and the early modern study of the heavens.

A Fellow of the Royal Society, Hadley also improved telescope designs to enhance observational precision. His innovations paved the way for the development of the sextant, which became essential for maritime exploration during the Age of Sail.

Görner's impact on Leipzig's musical institutions and his role as an educator contributed to the city's rich cultural heritage.

Joseph Black was a pioneering French-Scottish physician and chemist in the 18th century. He is best known for formulating the concept of latent heat and specific heat, laying the groundwork for modern thermodynamics. In 1754, Black discovered carbon dioxide, which he called 'fixed air', revolutionizing the study of gases. His experiments on heat and gases influenced contemporaries like James Watt and Antoine Lavoisier. Black served as a professor of chemistry at the University of Edinburgh, where he inspired a generation of scientists. His work bridged the gap between chemistry and physics and cemented his reputation as one of the founders of modern physical chemistry.

Henry Clinton was an English general who led British military efforts during the American Revolutionary War. Born in 1730, he rose through the ranks of the British Army to become Commander-in-Chief in North America from 1778 to 1782.
