Giacomo Candido

Giacomo Candido (1871 to 1941) was an Italian mathematician and historian of mathematics. He received his degree from the University of Pisa in 1897 and then taught mathematics in secondary schools, first at the Liceo of Galatina, then at Campobasso and from 1927 at Brindisi. He edited and contributed to the Periodico di Matematica per l'Insegnamento secondario and was one of the founders of the journal La Matematica elementare, written for teachers, engineers and students. He was an invited speaker at the International Congress of Mathematicians in Bologna in 1928 and in Zurich in 1932, and in 1934 he founded the Apulian branch of Mathesis, an Italian association of mathematics teachers. His name survives in Candido's identity, an algebraic identity about sums of squares and fourth powers that he devised in connection with Fibonacci numbers, and he is also remembered for his work on the history of mathematics.
