Lodovico Ferrari
A mathematical prodigy who, as a teenager, discovered the complete solution to the quartic equation, a problem that had stumped scholars for centuries.
1522–1565 (age 43)·Italian mathematician·Birthday: February 2
Biography
Born in Bologna, Lodovico Ferrari was plucked from obscurity as a servant boy by the mathematician Gerolamo Cardano, who recognized his raw talent. He became Cardano's student, secretary, and ultimately his collaborator in one of the most famous and contentious mathematical feuds of the Renaissance. Ferrari's singular triumph was devising a method to solve equations of the fourth degree, known as quartics. This breakthrough, published by Cardano in 1545, completed the work on cubic and quartic equations that had begun with Scipione del Ferro. His solution was a masterpiece of algebraic manipulation, involving a clever substitution that reduced the quartic to a solvable cubic. Ferrari's life was as volatile as his intellect; he engaged in public mathematical duels, taught mathematics, and amassed a fortune before retiring young. He died under mysterious circumstances in Bologna, leaving behind a legacy as the man who cracked a problem many considered insurmountable.
