List of Famous people with last name Beltrami

Eugenio Beltrami was an Italian mathematician notable for his work concerning differential geometry and mathematical physics. His work was noted especially for clarity of exposition. He was the first to prove consistency of non-Euclidean geometry by modeling it on a surface of constant curvature, the pseudosphere, and in the interior of an n-dimensional unit sphere, the so-called Beltrami–Klein model. He also developed singular value decomposition for matrices, which has been subsequently rediscovered several times. Beltrami's use of differential calculus for problems of mathematical physics indirectly influenced development of tensor calculus by Gregorio Ricci-Curbastro and Tullio Levi-Civita.

Giuseppe Beltrami was an Italian Cardinal of the Roman Catholic Church who served as Internuncio to the Netherlands from 1959 to 1967, and was elevated to the cardinalate in 1967.

Marco Beltrami is an American composer and conductor of film and television scores. A prolific musician, he has worked in a number of genres, including horror, action, science-fiction, Western, and superhero.

Giacomo Costantino Beltrami was an Italian jurist, author, and explorer, known for claiming to have discovered the headwaters of the Mississippi River in 1823 while on a trip through much of the United States. Beltrami County in Minnesota is named for him. He had an extensive network of notable figures for friends and acquaintances, including members of the powerful Medici family.
