Antonio Maria del Fiore also written as Fior, Fióre, Flòrido or Floridus, was a 15th- and 16th-century Italian mathematician connected with the school and institute of Bologna. He was involved in the disputes over authorship of the solution of the cubic equation.[1]
Biography
Del Fiore was a student of Scipione del Ferro, from whom he learned the formula for solving the particular cubic equation
and he began to boast that he was the only person capable of solving such equations.[2]
A few years later, Niccolò Tartaglia independently found the method used by del Ferro to solve these equations. Del Fiore challenged him to a public mathematical contest. Tartaglia defeated Del Fiore, solving in a short time the problems that Del Fiore had proposed, while Del Fiore was unable to solve any of the problems assigned to him by Tartaglia.
Later, Del Fiore took revenge by revealing to Gerolamo Cardano that the formula for solving cubic equations had been discovered by Scipione del Ferro and not by Tartaglia. This released Cardano from the promise he had made to Tartaglia not to reveal the formula.
With the help of Del Fiore and Lodovico Ferrari, Cardano expanded and generalized the formula, causing an indignant reaction from Tartaglia.
Ferrari challenged Tartaglia to a public contest in Milan. Favoured by the judges and by Tartaglia's speech impediment, since the contest was oral, Ferrari won the challenge and the rights to the formula.
Tartaglia withdrew and died in 1557, but Del Fiore himself, despite the contribution he had made to Cardano, was long forgotten.[2]
