Generally, the mass media in Britain, as elsewhere, treat the history of science as arcane knowledge. A few iconic tales do none the less come to permeate public consciousness. How do these come to be selected from the myriad of possible narratives?

One of the most enduring and well known of stories is the discovery of penicillin, which stretched from Alexander Fleming's observation in 1928 to the award of the Nobel prize to Fleming, Howard Florey and Ernst Chain in 1945 and the subsequent dominance of American companies in its manufacture. During the 1980s, when it appeared scandalous that monoclonal antibodies discovered in Cambridge, England, had not been patented by the British government, the parallel was often made with penicillin. An alternative use was made of the story when, in July 1995, a columnist in London's Evening Standard criticized massive expenditure on medical research and claimed that most drugs were discovered by accident. He sustained his thesis by merely putting in pointed parentheses the one word, ‘penicillin’. The same year, partisans found space in the correspondence columns of the New Scientist to return enthusiastically to the debate over the proper disposition of credit between Fleming and Florey. The BBC's Money Programme broadcast a piece on how best to support inventors today in October 1996; it included film of the Science Museum's coverage of Fleming.

The story of penicillin seems therefore bound, time and time again, to great issues in British culture: pride over technological prowess, resentment over the loss of opportunity, jealousy of American success, the National Health Service and the emergence of the modern pharmaceutical industry. The appeal of the story and meaning of its associations are matched by reverence for its material relics. In high profile auctions, the sale of samples prepared by Fleming raises thousands of pounds and is previewed in the newspages and on the radio. The original plate on which Fleming observed penicillin with its sterile ring surrounding the healing penicillin is one of the most familiar of historic relics (Figure 1).
