Georges Claude (24 September 1870 – 23 May 1960) was a French engineer and inventorHe is noted for his early work on the industrial liquefaction of air, for the invention and commercialization of neon lighting, and for a large experiment on generating energy by pumping cold seawater up from the depths. Considered by some to be "the Edison of France", he was an active collaborator with the German occupiers of France during the Second World War, for which he was imprisoned in 1945 and stripped of his honors.


 


In 1902 Claude devised what is now known as the Claude system for liquifying airThe 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.


 


Georges Claude studied at the École supérieure de physique et de chimie industrielles de la ville de Paris (ESPCI). He then held several positions. He was an electrical inspector in a cable factory and the laboratory manager in an electric works. He founded and edited a magazine, L'Étincelle Électrique (The Electric Spark); his important friendship with Jacques-Arsène d'Arsonval apparently dates from this time. About 1896, Claude learned of the explosion risk for bottled acetylene, which was used at the time for lighting. Acetylene is explosive when stored under pressure. Claude showed that acetylene dissolved well in acetone, equivalent to storing it under 25 atmospheres of pressure, which reduced the risk in handling the gas.


 


Inspired by Geissler tubes and by Daniel McFarlan Moore's invention of a nitrogen-based light (the "Moore tube"), Claude developed neon tube lighting to exploit the neon that was produced as a byproduct of his air liquefaction business. These were all "glow discharge" tubes that generate light when an electrical current is passed through the rarefied gas within the tube. 


 


Claude's first public demonstration of a large neon light was at the Paris Motor Show (Salon de l'Automobile et du Cycle), 3–18 December 1910. Claude's first patent filing for his technologies in France was on 7 March 1910. Claude himself wrote in 1913 that, in addition to a source of neon gas, there were two principal inventions that made neon lighting practicable. 


 


First were his methods for purifying the neon (or other inert gases such as argon). Claude developed techniques for purifying the inert gases within a completely sealed glass tube, which distinguished neon tube lighting from the Moore tubes; the latter had a device for replenishing the nitrogen or carbon dioxide gases within the tube. 


 


The second invention was ultimately crucial for the development of the Claude lighting business; it was a design for minimizing the degradation (by "sputtering") of the electrodes that transfer electrical current from the external power supply to the glowing gases within the sign.


 


The terms "neon light" and "neon sign" are now often applied to electrical lighting incorporating sealed glass tubes filled with argon, mercury vapor, or other gases instead of neon. In 1915 a U.S. patent was issued to Claude covering the design of the electrodes for neon lights.


 


In 1923, Georges Claude and his French company Claude Neon, introduced neon gas signs to the United States, by selling two to a Packard car dealership in Los AngelesEarle C. Anthony purchased the two signs reading "Packard" for $1,250 apiece. Neon lighting quickly became a popular fixture in outdoor advertising. Visible even in daylight, people would stop and stare at the first neon signs for hours, dubbed "liquid fire."


 


Claude's mentor and friend was Jacques-Arsène d'Arsonval, the inventor of the "Ocean Thermal Energy Conversion" (OTEC) concept. Claude was also the first person to build prototype plants of that technology. Claude built his plant in Cuba in 1930. The system produced 22 kilowatts of electricity with a low-pressure turbine.


 


Following the Allied liberation of France in 1944, Claude was taken into custody on 2 December 1944 because of his collaboration with the Axis PowersHe was removed from the French Academy of SciencesIn 1945 he was tried and convicted of propaganda work favoring collaboration, but was cleared of another charge that he helped design the V-1 flying bomb. He was condemned to life imprisonment, and was imprisoned. In 1950 he was released from prison, with acknowledgment of his research on ocean thermal energy conversion.
