Nikolai Lobachevsky (1792–1856) was a pioneering Russian mathematician best known for developing non-Euclidean geometry. Born in Nizhny Novgorod, he studied at Kazan University, where he later served as professor and rector. In the 1820s and 1830s, Lobachevsky challenged Euclid’s parallel postulate by proposing a system where, through a curved space, lines could diverge, forming what is now called hyperbolic geometry. His work, published in papers like “On the Principles of Geometry” (1829–1830), faced initial resistance but revolutionized mathematics, influencing relativity theory and modern physics. Lobachevsky’s contributions extended to education, as he advocated for scientific advancement in Russia.
