‎---- EDITION ORIGINALE ---- BEL EXEMPLAIRE ---- ENVOI DE Raoul PICTET à Antoine LECLERC ainsi libellé : "A Monsieur Antoine LECLERC ; hommage et reconnaissance - signé Raoul PICTET 19 Août 1914" ---- "After studying physics and chemistry in Geneva and Paris, PICTET returned to his native city and devoted himself to experimentation in the physics of low temperatures with an eye to the fast-growing and lucrative refrigeration industry. A compression refrigeration system that he developed, with sulfur dioxide as its cooling medium, functioned at a much lower pressure than competing systems ; contact with water, however, often turned the refrigerant into corrosive sulfurous acid. This system, protected by a number of patents, was marketed with some success. It was PICTET's researches that led to a scientific achievement which at once made him internationally famous. In December 1877, when Louis Paul CAILLETET was about to report his liquefaction of oxygen to the Paris Academy of Sciences, PICTET cabled from Geneva that he had achieved the same feat...".
