- Alexander Fleming's discovery of penicillin is often portrayed as a serendipitous event where a mold contaminated his Staphylococcus culture plate, leading to the observation of a 'ring of death' where bacteria were killed.
- Historical and scientific inconsistencies challenge the traditional narrative, including the unlikelihood of the mold growing on an already colonized plate and the two-month gap between the alleged discovery and the first recorded experiment.
- Ronald Hare proposed an alternative theory suggesting that the mold and staphylococci were inoculated simultaneously, and low lab temperatures allowed the mold to grow first, producing penicillin before the bacteria could proliferate.
- Robert Root-Bernstein's theory posits that Fleming was systematically searching for new lysozyme sources when he discovered penicillin, explaining the delay in recording the experiment and the misremembered details of the discovery.
- The source of the Penicillium mold is debated, with theories ranging from an open window to contamination from a nearby mycology lab run by C.J. La Touche.
- Root-Bernstein's theory reframes the discovery as part of an 'evolutionary process' in scientific research, emphasizing the combination of meticulous research and openness to unexpected findings.
- The story of penicillin's discovery highlights the importance of prepared minds in scientific breakthroughs and the often obscured, non-linear paths to major discoveries.
