He was awarded the gold medal of the Accademia Nazionale delle Scienze detta dei XL in 1920, while he was working at the University of Palermo: the members of the judging commission were Luigi Bianchi, Guido Castelnuovo and Tullio Levi-Civita. In 1924, on the 8th of June, he was elected ordinary non resident member of the mathematics division of the Accademia Pontaniana. On the 30th of May 1931 he was elected corresponding member of the Società Nazionale di Scienze, Lettere e Arti in Napoli: later on, precisely on the 11th of February 1933 and on the 4th of June 1949 he was elected, respectively, ordinary member and ordinary non resident member of the same academy. He was elected corresponding member of the Accademia Nazionale dei Lincei on July 15, 1935, and then national member on February 4, 1947. However, he was never awarded the royal prize of this academy, because he became a very early a member of it, thus losing the right to win a prize.
Work
Research activity
His scientific production includes more than 114 works, being papers, monographs and textbooks, 17 of which have been collected in his "Opere Scelte".
Teaching activity
Among his "allievi" there are some of the most important Italian mathematicians and mathematical physicists; a partial list of them is below:
. An important work, summarizing Signorini's approach to continuum mechanics of finite strains.
. A volume collecting the most important works of Antonio Signorini with an introduction and a commentary of Giuseppe Grioli.
