202. Louis Pasteur Autograph Letter

Signed on Rabies Experiments. ALS in French, signed “L. Pasteur,” one page, 4.5 x 3.5, January 28, 1885. Important letter about his research on a rabies vaccine, in part (translated): “I have received today, from the hands of Mr. Savadon, a dealer in Gray, a dog that has been attacked by a rabid dog. It will not leave my kennel where I will try to make him resistant to rabies despite the bite being probably at least four days old.” In very good to fine condition, with a fragile central vertical fold, reinforced with tape on the reverse.

After five years of extensive study of the rabies virus and the successful treatment of several infected dogs, Louis Pasteur faced his first human patient in July of 1885. Certain that the severely bitten nine-year-old Joseph Meister would not survive without treatment, he began the course of the 13 injections; after administering all 13, one each day, in progressively stronger doses, Meister regained strength and never developed rabies. After a second successful treatment on a bitten shepherd which began in October, word spread and people began to seek him out for the vaccinations. A remarkable letter by the scientist penned at the height of his rabies research. Starting Bid $200

201. Alfred Nobel Autograph Letter Signed on Patents. Swedish chemist, engineer, inventor, businessman, and philanthropist (1833–1896) known for inventing dynamite and for bequeathing his fortune for the establishment of the Nobel Prize. ALS in Swedish, signed “A. Nobel,” one page, 5.25 x 8, February 25, 1896. Handwritten letter to Oscar Linngstrom, commenting on patents by Swedish engineer Gustaf de Laval, who made important contributions to the design of steam turbines and centrifugal separation machinery for dairy. In part (translated): “It is very interesting that the matter so far has come up to my expectations. But the principle does not seem to be new, to judge by De Laval’s patent, we must first of all find out what has already been done. While this would involve expenses and loss of time it is still cheaper than to carry out something that has been done already. It is possible that only unsuccessful experiments have been made, but it is necessary to know about them and to judge their scope in the way of patents.” In fine condition. Intriguing content from the founder of the Nobel Prize, connecting him to a fellow Swedish inventor. Starting Bid $500
