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.
Absolute Genius with Dick and Dom is a British television series broadcast on CBBC and presented by Richard McCourt and Dominic Wood (Dick and Dom).In each episode the duo study the work of a genius (three geniuses in later series) and attempt to recreate one of their ideas, occasionally with some improvements using technology not available in the subject's lifetime.
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.

[146] Penicillin: Sir Alexander Fleming (1881–1955) [9]
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.

Engineers during World War Two test a model of a Halifax bomber in a wind tunnel, an invention that dates back to 1871.. The following is a list and timeline of innovations as well as inventions and discoveries that involved British people or the United Kingdom including predecessor states in the history of the formation of the United Kingdom.
This led him and Florey to revisit the work of Alexander Fleming, who had described penicillin nine years earlier. Chain and Florey went on to discover penicillin's therapeutic action and its chemical composition. Chain and Florey discovered how to isolate and concentrate the germ-killing agent in penicillin.
