Denis Papin

Born 22 Aug 1647; died c. 1712 .French-English physicist who invented the pressure cooker (1679). He assisted Dutch physicist Christiaan Huygens with air-pump experiments, and went to London in 1675 to work with the English physicist Robert Boyle. A few years later, Papin invented his steam digester (pressure cooker), a closed vessel with a tightly fitting lid that confined the steam at a higher pressure, considerably raising the boiling point of the water. A safety valve of his own invention prevented explosions. Observing that the enclosed steam in his cooker tended to raise the lid, Papin conceived of the use of steam to drive a piston in a cylinder, the basic design for early steam engines. He never built an engine of his own, but his idea was improved by others and led to the development of the steam engine, a major contribution to the Industrial Revolution.
