The British biologist and pharmacologist Alexander Fleming gave this sample of the mould Penicillium notatum to a colleague at St Mary's Hospital, London, in 1935.
Seven years earlier, Fleming had discovered by chance that this species of mould produces a substance he called 'Penicillin' that was found to have powerful antibiotic properties.
