The Medical School had Cecil George Paine. This photo was two future Nobel Prize taken in the mid 1930s. The power of penicillin to kill bacteria was first observed in 1928 by Alexander Fleming, winners on its staff in the who published his results but was unable to purify the antibiotic for medical use. He provided a culture of his penicillin-producing isolate of Penicillium notatum to 1930s – Howard Florey Cecil George Paine , who had qualified as a doctor at St Mary’s Hospital Medical School in London where Fleming worked. In 1929, Paine moved to Sheffield as Assistant Pathologist and Hans Krebs. at the Royal Infirmary and Lecturer in Pathology at the University. He used a crude filtrate produced by Fleming’s mould to successfully treat eye infections in 1929–30. Shortly afterwards he left the Infirmary, abandoning his experiments with penicillin while concentrating on puerperal sepsis in his new post as Consultant Pathologist at Paine’s case notes, of 28 August 1930, Sheffield’s Jessop Hospital (1931–70). He did, however, mention his findings to Fleming which show his use of ‘pinicillin’ at the and to Howard Florey, then Professor of Pathology at the Sheffield Medical School. foot of the first page. Florey went on, with a team at Oxford, to purify penicillin; doubtless Paine’s work helped convince him of its medical potential. Howard Florey qualified as a doctor in Australia in 1921. Awarded a Rhodes Scholarship, he worked his passage as a ship’s surgeon to England. After a short period at Oxford, he became a lecturer in the Pathology Department at Cambridge in 1927. Five years later, he was appointed Joseph Hunter Professor of Pathology at Sheffield. Here he showed that curare controls tetanus spasms and worked on the bacteriolytic agent lysozyme, another of Fleming’s discoveries, but this work languished for want of a biochemist’s input. Ironically, he left Sheffield just before the supremely talented biochemist Hans Krebs arrived.

All the treated mice survived, while the untreated died within hours. Further experiments demonstrated the amazing therapeutic potential of penicillin. Fleming, Florey and Chain were awarded the Nobel Prize for Medicine/Physiology in 1945, and Florey received many other honours, including the Order of Merit and an honorary degree (DSc) from the University of Sheffield. He was ennobled in 1965. The contribution of Cecil George Paine to the use of penicillin was largely overlooked until 1986, when he was interviewed by Dr Milton Wainwright (Department of Molecular Biology and Biotechnology), and Dr Harold Swan (Medical School) found case notes relating to his work. Together, Wainwright and Swan reconstructed the story of how Paine used crude penicillin filtrates to successfully treat eye infections (ophthalmia neonatorum) in two babies.

Simple infections, earaches, menial operations, and diseases, like syphilis and pneumonia, would possibly all end fatally, shortening the life expectancy of the population, affecting everything from family-size and marriage to retirement plans and insurance policies. So how did this “wonder drug” come into existence and who is behind the development of penicillin? The majority of the population has heard the “Eureka!” story of Alexander Fleming and his famous petri dish with the unusual mold growth, Penicillium notatum. Very few realize that there are not only different variations of the Fleming discovery but that there are also other people who were vitally important to the development of penicillin as an effective drug.

  • Warburg Effect(S)—A Biographical Sketch of Otto Warburg and His Impacts on Tumor Metabolism Angela M
    Otto Cancer & Metabolism (2016) 4:5 DOI 10.1186/s40170-016-0145-9 REVIEW Open Access Warburg effect(s)—a biographical sketch of Otto Warburg and his impacts on tumor metabolism Angela M. Otto Abstract Virtually everyone working in cancer research is familiar with the “Warburg effect”, i.e., anaerobic glycolysis in the presence of oxygen in tumor cells. However, few people nowadays are aware of what lead Otto Warburg to the discovery of this observation and how his other scientific contributions are seminal to our present knowledge of metabolic and energetic processes in cells. Since science is a human endeavor, and a scientist is imbedded in a network of social and academic contacts, it is worth taking a glimpse into the biography of Otto Warburg to illustrate some of these influences and the historical landmarks in his life. His creative and innovative thinking and his experimental virtuosity set the framework for his scientific achievements, which were pioneering not only for cancer research. Here, I shall allude to the prestigious family background in imperial Germany; his relationships to Einstein, Meyerhof, Krebs, and other Nobel and notable scientists; his innovative technical developments and their applications in the advancement of biomedical sciences, including the manometer, tissue slicing, and cell cultivation. The latter were experimental prerequisites for the first metabolic measurements with tumor cells in the 1920s. In the 1930s–1940s, he improved spectrophotometry for chemical analysis and developed the optical tests for measuring activities of glycolytic enzymes. Warburg’s reputation brought him invitations to the USA and contacts with the Rockefeller Foundation; he received the Nobel Prize in 1931.

  • René Dubos, Tuberculosis, and the “Ecological Facets of Virulence”
    HPLS (2017) 39:15 DOI 10.1007/s40656-017-0142-5 ORIGINAL PAPER René Dubos, tuberculosis, and the “ecological facets of virulence” Mark Honigsbaum1 Received: 15 January 2017 / Accepted: 23 June 2017 / Published online: 4 July 2017 © The Author(s) 2017. This article is an open access publication Abstract Reflecting on his scientific career toward the end of his life, the French- educated medical researcher Rene´ Dubos presented his flowering as an ecological thinker as a story of linear progression—the inevitable product of the intellectual seeds planted in his youth. But how much store should we set by Dubos’s account of his ecological journey? Resisting retrospective biographical readings, this paper seeks to relate the development of Dubos’s ecological ideas to his experimental practices and his career as a laboratory researcher. In particular, I focus on Dubos’s studies of tuberculosis at the Rockefeller Institute in the period 1944–1956—studies which began with an inquiry into the tubercle bacillus and the physiochemical determinants of virulence, but which soon encompassed a wider investigation of the influence of environmental forces and host–parasite interactions on susceptibility and resistance to infection in animal models. At the same time, through a close reading of Dubos’s scientific papers and correspondence, I show how he both drew on and distinguished his ecological ideas from those of other medical researchers such as Theobald Smith, Frank Macfarlane Burnet, and Frank Fenner. However, whereas Burnet and Fenner tended to view ecological interactions at the level of populations, Dubos focused on the interface of hosts and parasites in the physio- logical environments of individuals.

The first thing to note about this new work by Eric Lax, whose earlier efforts have been a well-regarded biography of Woody Allen and an engaging account of cancer chemotherapy, is that its title prom- ises a great deal — and does so rather late in the day. There is little doubt that, after more than half a century of personal reflections and scholarship, the story of the emergence of penicillin as a life-saving medicine remains remarkable — not least for the obstacles overcome and for the personalities of the trio of Nobel laureates involved: Alexander Fleming, Howard Florey and Ernst Chain. But promise of a true story begs the question of what has been on offer since 1945. And was there a miracle? Well, nearly, at least in the sense that the small team assembled by Florey at the Sir William Dunn School of Norman Heatley (below left) oversaw the mass production of penicillin in 1940s America. Pathology in Oxford, UK, in the dark and difficult early honorary doctorate of medi- from farther afield, such as the Yale papers years of the Second World cine, the first non-medical of John Fulton, Florey’s close friend and War, hardly seemed like a person to be so honoured.
