Evangelista Torricelli (October 15, 1608 - October 25, 1647) was an Italian physicist and mathematician.
After Galileo's death Torricelli was nominated grand-ducal mathematician and professor of mathematics in the Florentine academy.
Torricelli is also famous for the discovery of an infinitely long solid now called Gabriel's horn, whose surface area is infinite, but whose volume is finite.
