Answer:

The Scottish physician Alexander Fleming was the first to suggest that a Penicillium mould must secrete an antibacterial substance, and the first to concentrate the active substance involved, which he named penicillin, the first modern antibiotic, in 1928.

Answer:

Penicillin was discovered in London in September of 1928. As the story goes, Dr. Alexander Fleming, the bacteriologist on duty at St. Mary’s Hospital, returned from a summer vacation in Scotland to find a messy lab bench and a good deal more.
