Lodovico Ferrari

Lodovico Ferrari ( born February 2, 1522 Bologna, † October 5, 1565 ) was an Italian mathematician.

Ferrari was a professor of mathematics in Milan and Bologna.

Ferrari's family was originally from Milan. His grandfather Bartholomew had fled from Milan to Bologna. Ferraris parents died very young, and Ludovico Ferrari was recorded in 1536 at the age of 14 years as a penniless orphan Gerolamo Cardano of as a son in the household. Ferrari, who had received no schooling, was taught by Cardano self-described in Latin, Greek and mathematics. He was under the guidance of Cardano the solution of equations of the fourth degree. Cardano published in 1545, this solution together with its solution to cubic equations in his book Ars magna de Regulis Algebraicis.

Ferrari then led on behalf of Cardano a heated argument with the Reckoner Tartaglia, who had first found the solution for quadratic and cubic equations. The dispute led to the August 10, 1548 to a public discussion on the equations between the two rivals. Since Tartaglia was self Cardano's student Ferrari hopelessly outnumbered, he left Milan fled in the following night.

Ferrari retained in the subsequent period of public lectures on mathematics in Milan and went from 1548 to 1556 in the service of Cardinal Gonzaga of Mantua.

1564, he became professor of mathematics at Bologna, probably at the instigation of Cardano, of there who was a professor of medicine from 1563.

The asteroid ( 21331 ) Lodovicoferrari was named after him.
