Georges Claude - Liquefaction of Air

Liquefaction of Air

In 1902 Claude devised what is now known as the Claude system for liquifying air. The system enabled the production of industrial quantities of liquid nitrogen, oxygen, and argon; Claude's approach competed successfully with the earlier system of Carl von Linde (1895). Claude and businessman Paul Delorme founded L'Air Liquide, S.A. (Air Liquide), which is presently a large multinational corporation headquartered in Paris, France.
