On his deathbed del Ferro passed his formula on to his student, Antonio Fiore, who intended to use it as an ace up his sleeve in a contest against his rival Niccoló Tartaglia. But Tartaglia independently discovered the same method for solving the depressed cubic just in time and proceeded to wipe the floor with del Ferro's student.
The victorious Tartaglia had a fascinating life story apart from his victory in mathematical smack downs. His real name was Niccoló Fontana. A wound inflicted by a French soldier when he was young had left him with disfiguring scars and a stammer, leaving him stuck with the nickname Tartaglia, "the stammerer". His opponent in the battle in Milan church in 1548, Lodovico Ferrari, was fighting on behalf of yet another mathematician, Giralomo Cardano. Tartaglia had divulged his cubic method to Cardano, on the condition he swore a "most solemn oath, by the Sacred Gospels and his word as a gentleman," never to publish it. But when Cardano discovered that del Ferro had independently discovered the solution before Tartaglia he included it in his work, the Ars Magna (meaning "The great art"), published in 1545. Cardano gave both Tartaglia and del Ferro due credit, but Tartaglia was angry about his secret being revealed. The battle in Milan was the culmination of a terrible feud that had ensued as a result.
