Denis Papin

Denis Papin was a French-born British physicist who invented the pressure cooker and suggested the first cylinder and piston steam engine. Though his design was not practical, it was improved by others and led to the development of the steam engine, a major contribution to the Industrial Revolution. Papin assisted the Dutch physicist Christiaan Huygens with his air-pump experiments and went to London in 1675 to work with the English physicist Robert Boyle.
