Tartaglia, Niccoló Fontana (1499–1557)
Italian mathematician who, with along with Girolamo Cardano,
discovered the algebraic solution of the cubic.
He was also a well-known inventor of mathematical recreations. He devised
many arithmetical problems, and contributed especially to measuring
and weighing problems and to river-crossing
problems. Although his real name was Niccoló Fontana, he is always referred
to as Tartaglia, "the stammerer."
