Alexander fleming discovery of penicillin

How was penicillin developed?
Before antibiotics, a relatively minor infection could prove incurable or even deadly. Everything from paper cuts to childbirth had the potential to kill through bacterial infection.
The accidental discovery of a mouldy petri-dish in 1928 kickstarted a 20-year long journey to develop the world’s first mass produced drug that could clear a bacterial infection; penicillin. But why did it take so long?
The Accidental Discovery: Fleming’s Lab, St. Mary's Hospital, London. 1928 to 1929
In 1928 Dr Alexander Fleming returned from a holiday to find mould growing on a Petri dish of Staphylococcus bacteria. He noticed the mould seemed to be preventing the bacteria around it from growing. He soon identified that the mould produced a self-defence chemical that could kill bacteria. He named the substance penicillin.
Fleming published his findings and presented his discovery to the Medical Research Club. To his surprise, his peers showed little interest in his work.
Undeterred, he enlisted the help of several chemists, all leading experts in their fields, to help purify penicillin from the mould. None were successful. Professor Harold Raistrick, a Biochemist and expert in fungal substances enlisted by Fleming, declared "

In 1928 Alexander Fleming (1881–1955) discovered penicillin, though he did not realize the full significance of his discovery for at least another decade. He eventually received the Nobel Prize in Physiology or Medicine in 1945.
As far back as the 19th century, antagonism between certain bacteria and molds had been observed, and a name was given to this phenomenon—antibiosis—but little was made of these observations. A folk tradition using molds in medicine was similarly neglected. In 1928 Alexander Fleming discovered penicillin, made from the Penicillium notatum mold, but he did not receive the Nobel Prize in Physiology or Medicine for his discovery until 1945.
Fleming himself did not realize how important his discovery was; for a decade after, he focused instead on penicillin’s potential use as a topical antiseptic for wounds and surface infections and as a means of isolating certain bacteria in laboratory cultures. It was left to his fellow Nobelists, Howard Florey and Ernst Chain, to demonstrate in 1940 that penicillin could be used as a therapeutic agent to fight a large number of bacterial diseases.
The Road to St. Mary’s
Born in Lochfield, Ayrshire, Scotland, Fleming was the seventh of eight surviving children in a farm family. His father died when he was seven
