Lot 305: ALS in French, signed "L. Pasteur," one page, 5.25 x 8.25, Ecole Normal Superieure letterhead, March 28, 1865. Letter to Charrier, in full (translated): "I apologize for not being able to visit with you. Please send to me the saccharoles that you have at present. They were able to modify [all] we had. I would be obliged if you would send the others, if you are able, without too much trouble, and with certificates of the origin of the wines." In fine condition, with light brushing to lower portion of the letter. As the director of scientific studies at Ecole Normale, Pasteur's study of fermentation led to the 1865 patent and invention of 'pasteurization,' a process which ridded unwanted microorganisms in beverages like beer, milk, and wine when the liquids were heated to a temperature between 60° and 100° C. In the very same year, Pasteur helped save the silk industry by developing a method to prevent microbes from infecting silkworm eggs.
