1873 – 1941
Tullio Levi-Civita (1873–1941) was an Italian mathematician whose work on absolute differential calculus and tensor analysis provided the mathematical foundation for Einstein's general theory of relativity. Collaborating with Gregorio Ricci-Curbastro, he developed the systematic framework for covariant and contravariant tensors that made curved-spacetime geometry tractable. He also contributed foundational work on the concept of parallel transport and the geometric structure underlying relativistic physics.
Co-developed absolute differential calculus (tensor calculus) with Ricci-Curbastro, published in the landmark 1900 paper
Introduced the Levi-Civita connection, formalizing parallel transport on Riemannian manifolds
Provided mathematical tools essential to Einstein's formulation of general relativity
Introduced the Levi-Civita symbol (epsilon tensor) used throughout physics and geometry
Made significant contributions to celestial mechanics, including analysis of the three-body problem
