Gregorio Ricci-Curbastro

Born 12 Jan 1853; died 6 Aug 1925 at age 72.Italian mathematician instrumental in the development of the absolute differential calculus (also called the Ricci calculus), now known as tensor analysis. Ricci-Curbastro's early work was in mathematical physics, particularly on the laws of electric circuits and differential equations. He changed area somewhat to undertake research in differential geometry and was the inventor of the absolute differential calculus between 1884 and 1894. Ricci-Curbastro's absolute differential calculus became the foundation of tensor analysis and was used by Einstein in his theory of general relativity. As a councillor for his home town of Lugo, he was involved in many projects relating to the supply of water and to swamp drainage.
