Beltrami, Eugenio
Italian mathematician who pioneered modern non-Euclidean geometry. His work ranged over almost the whole field of pure and applied mathematics, but especially theories of surfaces and space of constant curvature.
Beltrami was born in Cremona, Lombardy, and studied mathematics at Pavia. He held academic posts at Bologna, Pisa, Pavia, and Rome.
In 1862 he published his first paper, an analysis of the differential geometry of curves, to which he would return in his most important paper, 'Saggio di interpretazione della geometria non-euclidia' 1868. This advanced a theory of hyperbolic space that laid the analytical base for the development of non-Euclidean geometry.
Beltrami demonstrated that the concepts and formulae of Russian mathematician Nikolai Lobachevsky's geometry are realized for geodesics on surfaces of constant negative curvature. He showed also that there are rotation surfaces of this kind - he called them 'pseudospherical surfaces'. He also demonstrated the usefulness of employing differential parameters in surface theory, thereby beginning the use of invariant methods in differential geometry.
After 1872 Beltrami switched his attention to questions of applied mathematics, especially problems in elasticity and electromagnetism.

    Beltrami, Eugenio
    (b. Nov. 16, 1835, Cremona, Lombardy, Austrian Empire [now in Italy]d. Feb. 18, 1900, Rome, Italy), Italian mathematician known for his concepts of non-Euclidean geometry, especially his theories of surfaces of constant curvature. Following his studies at the University of Pavia (1853-56) and later in Milan, Beltrami was invited to join the faculty at the University of Bologna in 1862 as a visiting professor of algebra and analytic geometry; four years later he was appointed professor of rational mechanics. He also held professorships at universities in Pisa, Rome, and Pavia. Influenced by N.I. Lobachevsky, C.F. Gauss, and Bernhard Riemann, Beltrami's work on the differential geometry of curves and surfaces removed any doubts about the validity of non-Euclidean geometry, and his method was soon followed by the German mathematician Felix Klein. Beltrami's four-volume work, Opere Ma te ma tiche (1902-20), published posthumously, contains his comments on a broad range of physical and mathematical subjects, including thermodynamics, elasticity, magnetism, optics, and electricity. Beltrami was a member of the Accademia dei Lincei, serving as president in 1898; he was elected senator a year before his death.

    A Brief Look at The Life and Works of Eugenio Beltrami
    By Dr. Mark Hughes
    Eugenio Beltrami was an Italian mathematician who played an important role in improving our understanding of non-Euclidean geometry. Beltrami was born on November 16, 1835 in Cremona. He was a student at universities in Pavia and Milan. His first academic position was at the University of Bologna. During his career, he was also associated with universities in Pisa, Rome and Pavia. Among Beltrami's non-mathematical activities was his service as a senator in the kingdom of Italy during his last year of life. He died on June 4, 1899 in Rome. Beltrami's life as a mathematician can be divided into two main stages. His earlier and more important work was in the field of geometry. Later, his interests turned towards applied mathematics, including works on elasticity, Maxwell's theory of electromagnetism and other topics of mathematical physics. Beltrami's 1868 paper, "Saggio di interpretazione della geometria non-euclidea" is considered to be his most important work. In this paper, Beltrami provided an important key towards the understanding of Hyperbolic Geometry, namely a model developed within the framework of Euclidean Geometry.

    Jacques Maritain Center: Thomistic Institute From DSB 1:599-600 (Beltrami, Eugenio): ...In a paper of 1865 Beltrami had shown that on surfaces of constant curvature, and only on them, the line elements ds can be written in such a form that the geodesics, and only these, are represented by linear expressions in u and v . For positive curvature R this form is . . . The geodesics in this case behave, locally speaking, like the great circles on a sphere. It now occurred to Beltrami that, by changing R to iR and a to ia , the line element thus obtained . . ., which defines surfaces of constant curvature -R , offers a new type of geometry for its geodesics inside the region u v a . This geometry is exactly that of the so-called non-Euclidean geometry of Lobachevski, if geodesics on such a surface are identified with the "straight lines" of non-Euclidean geometry.
