Education and career edit
In 1897 Candido received his Laurea (teaching degree) from the University of Pisa and started to teach mathematics: first, at the Liceo of Galatina, then at the Liceo of Campobasso and from 1927 at the Liceo of Brindisi.[1]
He was an editor and contributor for the Periodico di Matematica per l'Insegnamento secondario and was one of the founders of the journal La Matematica elementare (an intermediate-level journal for teachers, engineers and students).[2]
He was an Invited Speaker of the ICM in 1928 in Bologna[3] and in 1932 in Zürich. In 1934 he founded the Apulian branch of Mathesis, an Italian association of mathematics teachers.
He is also remembered for his work on the history of mathematics.
Candido's identity edit
Candido devised his eponymous identity to prove that
where Fn is the nth Fibonacci number.
The identity of Candido is that, for all real numbers x and y,[4][5]
It is easy to prove that the identity holds in any commutative ring.[4]
