Girolamo Cardano

Died 21 Sep 1576 at age 74 (born 24 Sep 1501). Italian physician, mathematician and astrologer who was the first to give a clinical description of typhus fever. His book, Ars magna ("Great Art," 1545) was one of the great achievements in the history of algebra, in which he published the solutions to the cubic and quartic equations. His mechanical inventions included the combination lock, the compass gimbal consisting of three concentric rings, and the universal joint to transmit rotary motion at various angles (as used in present-day vehicles). He contributed to hydrodynamics and held that perpetual motion is impossible, except in celestial bodies. Cardano published two encyclopedias of natural science, introduced the Cardan grille, a cryptographic tool (1550), and was a life-long believer as an astrologer. He died by suicide.«
