Jean-Baptiste L. Romé de l'Isle

(1736 - 1790)

French geologist and mineralogist

French geologist and mineralogist
A pioneering French geologist and mineralogist regarded as a founder of crystallography.
Jean-Baptiste L. Romé de l'Isle (1736–1790) was a pioneering French geologist and mineralogist who laid the foundations of modern crystallography. He authored the groundbreaking work 'Essai de cristallographie' which provided the first systematic classification of crystals based on their geometric forms. His meticulous studies of mineral symmetry and structure influenced the development of mineral chemistry. As a member of the French Academy of Sciences, he collaborated with his contemporaries, advancing geological surveys across Europe. His research established principles that are still used by geologists and crystallographers today.

Antonio de Ulloa

(1716 - 1795)

Spanish general, astronomer, and politician, 1st Colonial Governor of Louisiana

Spanish general astronomer and politician 1st Colonial Governor of Louisiana
Spanish naval officer, astronomer, and colonial governor noted for his scientific explorations and leadership in Louisiana.
Antonio de Ulloa (1716–1795) was a Spanish naval officer, mathematician, and natural philosopher who participated in the famed French Geodesic Mission to South America. He made significant contributions to astronomy and natural history by documenting new species and measuring meridian arcs near the equator. In 1766, he was appointed the first Spanish governor of Louisiana, where he navigated complex political challenges during the brief transfer of power. Ulloa’s diplomatic skills were tested when local colonists rebelled against his administration, ultimately leading to his recall to Spain. His writings on meteorology, mineralogy, and naval engineering influenced scientific thought across Europe.

Hasan Tahsini

(1811 - 1881)

Albanian astronomer, mathematician, and philosopher

Albanian astronomer mathematician and philosopher
Albanian astronomer, mathematician, and philosopher who pioneered modern scientific education in the Ottoman Empire.
Hasan Tahsini (1811–1881) was an Albanian polymath instrumental in introducing modern scientific instruction to the Ottoman world. Educated in Istanbul and Europe, he taught astronomy and mathematics at Darülfünun, the precursor to Istanbul University. Tahsini translated key European scientific works into Ottoman Turkish and authored treatises on astronomy, mechanics, and philosophy. His advocacy for empirical science and rational thought challenged traditional curricula and inspired a generation of Ottoman scholars. Despite opposition from conservative factions, his efforts laid the groundwork for modern scientific education in Turkey.

Pelageya Polubarinova-Kochina

(1899 - 1999)

Russian mathematician

Russian mathematician
Pioneering Russian mathematician renowned for her foundational work in fluid dynamics and applied mathematics.
Pelageya Polubarinova-Kochina specialized in hydrodynamics, elastic stability, and the theory of filtration. She earned her doctorate under the supervision of Nikolai Bogolyubov and became one of the first female professors of mathematics in the Soviet Union. Her 1952 monograph on filtration theory remains a classic reference in engineering and geophysics. Over her career, she authored numerous research papers on non-Newtonian fluids and elasticity theory. She was a member of the USSR Academy of Sciences and received multiple state honors. Polubarinova-Kochina's work paved the way for modern studies in mathematical physics and engineering applications.
