Penicillium Mould Created in 1935

“A sample of Penicillium mould presented by Alexander Fleming to Douglas Macleod, 1935.

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. This sample marks penicillin’s transition from an interesting phenomenon to a potential drug.”
