18059 Cavalieri           Discovered 1999 Dec. 15 by P. G. Comba at Prescott.
Bonaventura Cavalieri (1598-1647) was a friar and a professor at the University of Bologna. He developed the method of indivisibles, which enabled him to find integrals of polynomials and centers of gravity of many curvilinear figures. His work ultimately influenced Leibniz' discovery of the calculus.
