Sir Alexander Fleming FRS FRSE FRCS [2] (6 August 1881 – 11 March 1955) was a Scottish physician and microbiologist, best known for discovering the world's first broadly effective antibiotic substance, which he named penicillin.
Sample of penicillin mould presented by Alexander Fleming to Douglas Macleod in 1935. The discovery of penicillin was one of the most important scientific discoveries in the history of medicine. Ancient societies used moulds to treat infections and in the following centuries many people observed the inhibition of bacterial growth by moulds.
Fleming reported his findings to the British Journal of Experimental Pathology on 10 May 1929, and published them in the next month's issue, [42] [43] but the article failed to attract much attention. Fleming himself was quite unsure of the medical application of his work and was more concerned with its the application for bacterial isolation. [42]

In 1928, Sir Alexander Fleming postulated the existence of penicillin, a molecule produced by certain moulds that kills or stops the growth of certain kinds of bacteria. Fleming was working on a culture of disease-causing bacteria when he noticed the spores of a green mold, Penicillium rubens, [147] in one of his culture plates.

Hobby worked for Presbyterian Hospital and the Columbia Medical School from 1934 to 1943, where she joined a research team at Columbia College of Physicians and Surgeons that was researching potential human uses for penicillin. The drug was first discovered in 1928 by the Scottish physician and bacteriologist Alexander Fleming.
