Tartaglia was famed for his algebraic solution of cubic equations which was published in Cardan's Ars Magna .
Tartaglia's proper name was Niccolo Fontana although he is always known by his nickname. When the French sacked Brescia in 1512 the soldiers killed Tartaglia's father and left Tartaglia for dead with a sabre wound that cut his jaw and palate. The nickname Tartaglia means the 'stammerer' and, after this terrible wound, one can understand why he stammered.
Tartaglia was self taught in mathematics but, having an extraordinary ability, was able to earn his living teaching at Verona and Venice.
The first person known to have solved cubic equations algebraically was dal Ferro. On his deathbed dal Ferro passed on the secret to his (rather poor) student Fior. A competition to solve cubic equation was arranged between Fior and Tartaglia. Tartaglia, by winning the competition in 1535, is famed as the discoverer of a formula to solve cubic equations. Because negative numbers were not used there was more than one type of cubic equation and Tartaglia could solve all types, Fior only one type. Tartaglia confided his solution to Cardan on the condition that he would keep it secret. The method was, however, published by Cardan in Ars Magna in 1545.
Tartaglia wrote Nova Scientia (1537) on the application of mathematics to artillery fire. He described new ballistic methods and instruments, including the first firing tables.
Tartaglia also wrote a popular arithmetic text and was the first Italian translator and publisher of Euclid's Elements in 1543. He also published Latin editions of Archimedes's works.
