Charles Tellier
Charles Tellier (29 June 1828 – 19 October 1913) was a French engineer, born in Amiens. He early made a study of motors and compressed air. In 1868, he began experiments in refrigeration, which resulted ultimately in the refrigerating plant, as used on ocean vessels, to preserve meats and other perishable food. In 1911, Tellier was awarded the Joest prize by the French Institute and, in 1912, he was made Chevalier of the Legion of Honour. He wrote "Histoire d'une invention moderne, le frigorifique" (1910). Tellier died impoverished in Paris. Dimethyl ether was the first refrigerant, in 1876, Charles  Tellier bought the ex-Elder-Dempster a 690 tons cargo ship "Eboe" and fitted a Methyl-ether refrigerating plant of his design. The ship was renamed "Le Frigorifique" and successfully imported a cargo of refrigerated meat from Argentina. However the machinery could be improved and in 1877 another refrigerated ship called "Paraguay" with a refrigerating plant improved by Ferdinand Carré was put into service on the South American run.
