    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Loughborough University Institutional Repository La Moisissure et la Bactérie: Deconstructing the Fable of the Discovery of Penicillin by Ernest Duchesne Gilbert Shama Department of Chemical Engineering. Loughborough University Loughborough Leicestershire, LE11 3TU, UK. +44 1509 222514 [email protected] Abstract: Ernest Duchesne (1874–1912) completed his thesis on microbial antagonism in 1897 in Lyon. His work lay unknown for fifty years, but on being brought to light led to his being credited with having discovered penicillin prior to Alexander Fleming. The claims surrounding Duchesne are examined here both from the strictly microbiological perspective, and also for what they reveal about how the process of discovery is frequently misconstrued. The combined weight of evidence presented here militates strongly against the possibility that the species of Penicillium that Duchesne worked with produced penicillin. Keywords: Ernest Duchesne, Penicillin, Alexander Fleming, Penicillium 1 Introduction Following the appearance of an article on penicillin in The Times of London in the summer of 1942,1 Almroth Wright, head of the inoculation department at St Mary’s Hospital in Paddington, wrote to the editor concerning a colleague of his—a certain Alexander Fleming. In his letter, Wright pointed out that the newspaper had “refrained from putting the laurel wreath around anybody’s brow for [penicillin’s] discovery” and that “on the principle of palmam qui meruit ferat (let him bear the palm who has earned it) it should be decreed to Professor Fleming.”2 A number of commentators over the seventy years or so that have elapsed since the publication of this letter have sought to remove—snatch even—the wreath from Alexander Fleming’s brow and award it elsewhere.

Biographical Memoir COPYRIGHT 1965 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. CHARLES THOM November 11,1872-May 24,1956 BY KENNETH B. RAPER ITH THE DEATH of Charles Thom on May 24, 1956, at his Whome in Port Jefferson, New York, the nation lost one of its most colorful and most productive microbiologists. For more than half a century he was a consistent contributor to micro- biological literature, and during the course of his career he contributed much to the basic science in this field and to the practical application of microorganisms in agriculture and industry. While he was best known for his monumental studies on two genera of molds, Aspergillus and Penicillium, he was at home in the dairy, the canning factory, and the cotton field as well. His interests in biology stemmed from his boy- hood on the farm and from his early contacts with outstanding biologists who instilled in him an unquenchable zeal for the study of living systems, large and small. The pattern of his scientific work was determined in substantial part by the vari- ous official positions which he held in the United States Depart- ment of Agriculture from 1904 to 1942, but sustained by an The writer was closely associated with Dr.

SALMON, D. V. M., Chief of Bureau. THE CAMEMBERT TYPE OF SOFT CHEESE IN THE UNITED STATES. BY H. W. CONN, CHARLES THOM, A. W. BOSWORTH, W. A. STOCKING, JR., AND T. W. ISSAJEFF. WASHINGTON: GOVERNMENT PRINTING OFFICE. 1905. LETTER OF TRANSMITTAL U. S. DEPARTMENT OF AGRICULTURE, BUREAU OF ANIMAL INDUSTRY, Washington, D. C, March 23,1905, SIR: I have the honor to transmit herewith a manuscript entitled "The Camembert type of soft cheese in the United States," and to recommend its publication as a bulletin. This paper represents the initiatory effort in a series of cooperative experiments which has been undertaken by the Dairy Division of this Bureau in conjunction with the Storrs (Conn.) Agricultural Experi- ment Station. The full scope and character of these experiments are explained in the introductory chapter on the next page. It is anticipated this work will result in much benefit "to a large class of our farmers and dairymen, who may thus find a new and highly remunerative outlet for their surplus milk supply. Respectfully, D. E. SALMON, Chief of Bureau. Hon. JAMES WILSON, . Secretary of Agriculture. 2 INTRODUCTION. The investigations in soft-cheese making were undertaken by the Storrs Agricultural Experiment Station with the hope that there might be developed a new industry especially adapted to New Eng- land conditions. The Camembert type of soft cheese seems espe- cially adapted to home manufacture. The process of manufacture has, however, been held as a trade secret and no source of information has been available for those who may have desired to make this type of cheese.

  • The Lipman Log Newsletter, 2017
    Department of Biochemistry and Microbiology photo by Penny Carlson 2 Department Chair, Max Ha ggblom We are pleased to present you this latest, and redesigned, issue of the Lipman Log, with highlights from the 2016-2017 academic year. This has been an eventful year, with new members to our faculty and staff, promotions, awards, theses defenses,… and renovations. Liping Zhao joined the department in January 2017 (from Shanghai Jiao Tong University) as the Eveleigh- Fenton Chair in Applied Microbiology. Professor Zhao is internationally recognized as one of the leading researchers in microbial ecology, in particular the study of the gut microbiome. His work focuses on elucidating the interactions between nutrition and gut microbiota in onset and progression of chronic diseases such as obesity and diabetes. Debashish Bhattacharya joined our department (from Ecology, Evolution and Natural Resources) in July. Professor Bhattacharya studies the origin of the photosynthetic organelle, the plas- tid, in diverse algae and aims to understand how organelles are integrated into host metabolism. Arek Kulczyk is a new Assistant Professor with a joint appointment at the Center for Integrative Proteomics Research. He integrates structural approaches, in particular single-particle cryo-electron microscopy and single-molecule methods to study DNA replication and repair in human mitochondria. We also welcomed two new teaching faculty members Drs. Sharron Crane (Biochemistry) and Ramaydalis Keddis (Microbiology). Our non-tenure track faculty fill critical roles in the teaching, research, and engagement missions of our department. The annual Microbiology Symposium continues to bring faculty and students from across Rutgers together to hear about the most recent advances in microbiology research.

I always stepped into the only suitable opening I could see on my horizon. Emerson described this kind of progression: "Each man has his own vocation … there is one direction in which all space is open to him. He has faculties silently inviting him thither to endless exertion. He is like a ship in a river; he runs against obstructions on every side but one, on that side every obstruction is taken away and he sweeps over a deepening channel into an infinite sea.” I always thought that somehow, I drifted into the work for which I was best adapted. I grew up on farm in a Welsh community of northern Pennsylvania where my paternal grandparents settled when they came from Wales in 1831. I received my primary education in the little country schoolhouse where we had good teachers most of the time.
