Which Was The First-ever Antibiotic?

The first-ever antibiotic is penicillin. It was discovered by Alexander Fleming in the year 1928. The discovery was considered by some as a “happy accident”, where a culture of Staphylococci had been accidentally left open and was contaminated by a green mould.

On the petri dish, Flemming had observed an area where there was no bacterial growth. He attributed the inhibition of bacterial growth to the green mould. A deeper analysis concluded a substance released by the mould was responsible for the effect on the bacteria. 

Though there were many other scientists who had stumbled upon this phenomenon, it was Alexander Fleming who was able to isolate the reason for this effect.
