Very poor, I was known as the "stutterer" because my face was mutlilated in a raid by French troops when I was 10 years old.
Though I was a mathematics teacher at schools in Verona, Venice, and Bresica, I first published a text on the mathematical theory of gunnery.
My publication Trattato Generale became a respected compilation of the practical and commercial mathematics known in my time.
I also produced the first Italian translation of Euclid and the first Latin translation of Archimedes.
As part of a public contest, I gained fame by being able to solve a special type of cubic...and reluctantly shared my technique with Cardano as part of an oath of secrecy.
That evil man! Cardano not only published my technique in his new text, but he also took credit for the idea himself!
My life ended in poverty, after I lost a final public contest (required to get a teaching position) trying to redeem myself and shame Cardano.
