	Ernest Duchesne - Wikipedia, the free encyclopedia
		Ernest Duchesne (May 30, 1874 – April 12, 1912) was a French physician who noted that certain moulds kill bacteria.
		Duchesne had made his breakthrough by observing how the Arab stable boys at the army hospital kept their saddles in a dark and damp room to encourage mould to grow on them.
		Duchesne served a one year internship at Val de Grâce before he was appointed a 2nd class Major of Medicine in the 2nd Regiment de Hussards de Senlis.

	Discovery, Chance and the Scientific Method
		Another event, although overlooked at the time, in the string of occurrences which led to the discovery of penicillin was a dissertation written in 1897 by the French medical student, Ernest Duchesne.
		In his dissertation, Duchesne reported the discovery, partial refinement, and successful testing on animals of a substance with antibiotic properties - that is a substance which inhibited bacterial growth.
		Duchesne died at an early age in 1912, never seeing the world's acceptance and use of his important discovery.

		French physician Ernest Duchesne noted in his 1896 thesis that certain Penicillium molds killed bacteria.
		Duchesne died within a few years, and his research was forgotten for a generation, until an accident intervened.
		Alexander Fleming had been culturing bacteria on agar plates, one of which was ruined by an accidental fungal contamination.

	Penicillin - Wikipedia, the free encyclopedia
		Penicillin was originally isolated from the Penicillium chrysogenum (formerly Penicillium notatum) mold.
		The antibiotic effect was originally discovered by French medical student Ernest Duchesne studying Penicillium glaucum in 1896, but his discovery was ignored by the Institut Pasteur.
		Another Institut Pasteur scientist, Costa Rican Clodomiro Picado Twight was the first to record the antibiotic effect of Penicillium in 1923.

		The antibiotic effect was originally discovered by a young French medical student Ernest Duchesne studying Penicillium glaucum in 1896 but his work was forgotten.
		It was later rediscovered in 1928 by Alexander Fleming who noticed that a halo of inhibition of bacterial growth in a culture of Staphylococcus around a contaminant blue-green mould.

		Antibiotics Ernest Duchesne discovered antibiotics in 1896 and then they were discovered again by Alexander Fleming in 1928.
		When Duchesne and Fleming used these antibiotics, they did so on a small scale and the results didn’t include drug resistant bacteria.
		How Scientists are trying to cure Drug-Resistant bacteria When Ernest Duchesne discovered antibiotics, the world didn’t have any such thing as a miracle drug capable of curing humanity of many diseases thought incurable.

		The doctor's name is Ernest Augustin Duchesne, and regrettably, his doctoral thesis, "Study of vital competition in the micro-organisms: antagonisms between the moulds and the microbes," has fallen on deaf ears.

		Du Pont, realizing that his family business needs to diversify away from its dependence on gunpowder (cyclic, and at times the cause of opprobrium directed toward it) suggests that his firm's chemical knowledge and financial backing could be used to develop an extract with medicinal properties, and invites Duchesne to America.

		Most dramatically, Ernest Duchesne had completed a doctoral dissertation in 1897 on the evolutionary competition among microorganisms, focusing on the interaction between E. coli and Penicillium glaucum.
		Duchesne reported how the mold had eliminated the bacteria in culture.
		He had also inoculated animals with both the mold and a lethal dose of typhoid bacilli, showing that the mold prevented the animals from contracting typhoid.

	Jack's "Bugs in the News" - What the Heck is Penicillin?
		Like many discoveries in science, the discovery of penicillin was actually a re-discovery, and partly due to the fact that chance usually favors the "prepared mind".
		The earliest record of a substance produced by a mold which could apparently kill bacteria was made in 1896 or so, by a French medical student named Ernest Duchesne.
		"Visiting your pages while looking for information on Ernest Duchesne and various scientific ideas that seem to arrive ahead of their time put me in mind of a nice anecdote my father-in-law, Jack Judah, tells of his early days in Oxford when he was a medical student.

		When penicillin became widely available during the second world war, it was a medical miracle, rapidly vanquishing the biggest wartime killer--infected wounds.
		Discovered initially by a French medical student, Ernest Duchesne, in 1896, and then rediscovered by Scottish physician Alexander Fleming in 1928, the product of the soil mold Penicillium crippled many types of disease-causing bacteria.
		But just four years after drug companies began mass-producing penicillin in 1943, microbes began appearing that could resist it.

		Fleming's work was recognized as the first scientific study of penicillin.

		In fact, technically speaking, Fleming may have rediscovered a substance that had been found before.
		In 1896, the French medical student Ernest Duchesne showed antibiotic properties of the mold Penicillium, but did not report a connection between the fungus and a substance that had antibacterial properties.
		Penicillium was unknown to the scientific community until Fleming discovered the phenomenon and the substance, and named it penicillin.
