Luigi Cremona
Antonio Luigi Gaudenzio Giuseppe Cremona ( born December 7, 1830 in Pavia, Lombardy, † June 10, 1903 in Rome) was an Italian mathematician, structural engineers and politicians last.
Cremona grew up and studied in Pavia. In the uprisings 1848/1849 he participated in as a sergeant in the defense of Venice against the Austrians. Because of their bravery they were given free passage and Cremona began his engineering studies in Pavia continued. He also studied mathematics at Francesco Brioschi and Felice Casorati. In 1852 he received his doctorate, but could not find a teaching job after initially because of its revolutionary past and gave private lessons with different families, but already published the way scientific work. In 1857, he was a high school teacher in Cremona in 1859 in Milan. In 1860 he was royal decree out shortly before the unification of Italy in Bologna professor and from 1866 in Milan at the Polytechnic Institute. Since 1873 he was at the University of Rome and head of the School of Engineering. In 1879 he went into politics and became a senator. After he was Minister of Education, he gave up the scientific work. Most recently, he was Vice President of the Italian Parliament. He died of a heart attack.
He developed the Cremonaplan ( Cremona - force diagram ), a graphic method to determine member forces of statically determinate trusses. Here he built on the work of James Clerk Maxwell. The Cremonaplan is still in the structural analysis a simple method of frame analysis and the truss theory. His work also includes geometric works on algebraic curves and surfaces. Here the Cremona transformations are named after him. He examined in several papers 1863-1865, for which he received the 1866 Steiner Prize. Cremona was an excellent teacher and was one of the founders of the Italian geometric school. One of his pupils was Giuseppe Veronese.
