biography

Ascoli was the son of the mathematician Giulio Ascoli . He went to school in Livorno and in 1903 began his studies in civil engineering and then mathematics at the University of Pisa , where Eugenio Bertini and Luigi Bianchi were his teachers. In 1907 he received his Laureate degree with a thesis on singularities of analytical functions. He was at the chair for a short time, but then had to earn money because of family problems and worked as an engineer in the electrical engineering industry. For health reasons, he switched to a career as a school teacher. In 1909 he became a mathematics teacher at the technical school in Spoleto , from 1911 to 1913 in Cagliari , then until 1915 in Caserta and 1915/16 in Florence. In 1913 his geometry textbook for technical schools was published. He then served as an officer in the artillery in World War I and was wounded by shrapnel. From 1919 he was again a teacher at technical schools, first in Parma and from 1920 in Turin at the technical institute and from 1924 at the newly founded Liceo Scientifico. In 1924 his analysis textbook for technical schools was published. In 1925 he married Mauriziana Sossi, with whom he had two children.

In Turin he began active mathematical research and from 1926 to 1930 published important articles on partial differential equations (Dirichlet problem, Laplace equation in hyperbolic spaces, singularities of harmonic functions). In 1930 he applied for a professorship at the University of Cagliari in a competition and came third. In 1932 he became professor of analysis in Pisa and in 1934 in Milan. In the mid-1930s, Ascoli published a monograph on elliptical and parabolic partial differential equations (Equazioni a derivate parziali dei tipi ellittico e parabolico). Due to the anti-Semitic laws passed by the Italian fascist government in 1938, he lost his chair and had to leave the university. He then lived in Turin and, after the Germans took power in Italy in 1943, in a village (Dusino San Michele) in the province of Asti in Piedmont. He gave private tuition and was supported by the Jewish community in Milan and by Mauro Picone in Rome, who encouraged him to continue research.

From 1945 he taught again at the University of Milan and from 1948 at the University of Turin, where he mainly trained school teachers in mathematics. His lectures on elementary mathematics from the higher point of view, which were also illustrated with examples from the history of mathematics, appeared in 1952 (Lezioni di Matematiche complementari). He also gave introductory courses in mathematical culture and lectures on higher analysis and function theory.

In 1947 he became a corresponding member of the Accademia dei Lincei , in 1952 of the Turin Academy of Sciences and in 1953 of the Milan Academy of Sciences (Istituto Lombardo). In 1950 he became president of the Turin section of Mathesis. In 1953 he became a member of the International Commission on Mathematical Instruction and in 1955 President of the Italian National Commission for Mathematical Education, which he remained until 1957.
