Born in Turin, Sardinia-Piedmont, people still aregue over whether I was a French mathematician or an Italian mathematician.
I was one of eleven children, the only one to survive beyond infancy.
Before twenty years old, I was a mathematics professor at the Royal Artillary School in Turin, moved on to succeed Euler as a mathematics professor in Berlin, and ended my career as a mathematics professor in Paris.
I created a whole new field within algebra by my relation of the roots of am equation to the theory of permutations.
I prided myself on my ability to express things analytically, elegantly, and compactly (e.g. introducing the format of a determinant), and even proudly wrote a mathematics text that did not contain a single diagram.
