1792–1856 (age 64)
Biography
Nikolai Ivanovich Lobachevsky was a groundbreaking Russian mathematician and one of the founders of non-Euclidean geometry. His revolutionary work challenged centuries of mathematical orthodoxy and established him as one of the most important mathematical minds of the 19th century, earning him international recognition and respect.
Lobachevsky's contributions to mathematics fundamentally altered the course of geometric theory and influenced subsequent developments in physics and philosophy. His legacy extends far beyond his lifetime, as his non-Euclidean geometry became essential to Einstein's theory of general relativity and continues to shape modern mathematics and theoretical physics.
