Enrico Betti
Enrico Betti was an Italian mathematician, now remembered mostly for his 1871 paper on topology that led to the later naming after him of the Betti numbers. He worked also on the theory of equations, giving early expositions of Galois theory. He also discovered Bettis theorem, a result in the theory of elasticity.
Betti was born in Pistoia, Tuscany. He graduated from the University of Pisa in 1846 under Giuseppe Doveri160 . In Pisa, he was also a student of Ottaviano Fabrizio Mossotti and Carlo Matteucci. After a time teaching, he held an appointment there from 1857. In 1858 he toured Europe with Francesco Brioschi and Felice Casorati, meeting Bernhard Riemann. Later he worked in the area of theoretical physics opened up by Riemanns work. He was also closely involved in academic politics, and the politics of the new Italian state.
