Person: Gigli, Duilio
Duilio Gigli was an Italian mathematician who produced works on algebra, geometry and mathematical analysis.
Mathematical Profile (Excerpt):
 Torquato Gigli (18451936), born in Sansepolcro, studied chemical science at Pisa and lectured at the University as well as becoming head of the municipal chemical laboratory for many years.
 After his studies at a classical school in Pavia, Duilio Gigli studied mathematics at the Scuola normale superiore in Pisa, where he was taught by Luigi Bianchi.
 Following his doctorate Gigli spent another year undertaking further studies at Pisa; then he was appointed as an assistant at the University of Pisa.
 From 1910 Gigli taught at the Foscolo High School in Pavia, then at Portoferraio, Forlì, Sondrio and finally at Sassari in Sardinia before returning again to the Foscolo di Pavia (where he was also vicepresident).
 Regarding the concept of number, Gigli referred, among the many references, directly to the arithmetic of Giuseppe Peano, and tried to use his investigations into the fundamentals in his teaching.
 in 1930, under the editorship of Luigi Berzolari (18631949), Giulio Vivanti (18591949), and Duilio Gigli (1878 1933), appeared the first part of the first volume of 'Enciclopedia dette matematiche elementari'; the second part was published in 1932, both parts (each with its own author index) making a volume of nearly 1100 pages.
 While paying homage to Professor Gigli's thought effort, we will admit that conciseness is not always the prime quality of his explanations and demonstrations; this may be due to the point of view he wanted to take.
Born 8 January 1878, Sansepolcro, Alta Valle del Tevere, Italy. Died 10 May 1933, Pavia, Italy.
