Guido Castelnuovo

Guido Castelnuovo ( born August 14, 1865 in Venice, † April 27, 1952 in Rome ) was an Italian mathematician who worked mainly in the field of algebraic geometry.

The son of a well-known novelists studied mathematics at Giuseppe Veronese in Padua, where he graduated in 1886. In 1888 he went as assistant to Enrico D' Ovidio at the University of Turin, with its students Corrado Segre he corresponded already. In 1891 he became professor of geometry in Rome and thus a colleague of Luigi Cremona, who was mainly active as a politician but. In 1935, he retired. During the Second World War he was hiding as many Roman Jews forced and held courses also submerged Jewish students from. After the war he became president of the Accademia dei Lincei, to which he belonged as a corresponding and since 1918 as a regular member ( socio nazionale ) since 1901, and from which he had been excluded in 1938 as a Jew, and in 1949 a senator for life. In 1923 he was elected a member of the Leopoldina. Castel Nuovo main area of ​​work was the algebraic geometry. In his time in Turin he gave the theory of linear flocks of Brill and Max Noether (whose obituary he with Francesco Severi and Enriques he wrote in Mathematische Annalen Bd.93 1925 ) is a projective- geometric interpretation. Federigo Enriques With he was in the Italian school leader in the classification program algebraic surfaces.

He was also interested in probability theory, which he wrote in 1918 a two-volume work ( and a book published in 1937 with Herman in Paris French book ), and in questions of mathematics didactics. He also wrote in 1938 a book on the origins of the infinitesimal calculus.

In 1928 he gave a plenary lecture at the International Congress of Mathematicians in Bologna (La scuola italiana e la geometria algebrica ).

His daughter Emma Castelnuovo (* 1913) is a well known in Italy Math Teaching methods.
