Alexander Fleming discovered penicillin in 1928. When Fleming left a dish of staphylococcus bacteria out for a couple of days accidentally, the dish had bacterial growth on one area while another area had a patch of mold growing.
It was discovered by Fleming, who was experimenting with bacteria. A mold accidentally entered the plate, which killed all of the bacteria. He later discovered and experiemented with it making 'Penicillen', a bacteria fighting injection. It later saved his life when he got a lung disease.
Penicillin is one of the earliest discoveredand widely used antibiotic agents, derived from the Penicillium mold. Antibiotics are natural substances that are released by bacteria and fungi into the their environment, as a means of inhibiting other organisms - it is chemical warfare on a microscopic scale.
Alexander Fleming was a doctor and bacteriologist who discovered penicillin (1929), receiving the Nobel Prize in 1945.
It was not until 1939 that Dr. Howard Florey, a future Nobel Laureate, and three colleagues at Oxford University began intensive research and were able to demonstrate penicillin's ability to kill infectious bacteria.
As the war with Germany continued to drain industrial and government resources, the British scientists could not produce the quantities of penicillin needed for clinical trials on humans and turned to the United States for help. They were quickly referred to the Peoria Lab where scientists were already working on fermentation methods to increase the growth rate of fungal cultures.
One July 9, 1941, Howard Florey and Norman Heatley, Oxford University Scientists came to the U.S. with a small but valuable package containing a small amount of penicillin to begin work.
In 1943, the required clinical trials were performed and penicillin was shown to be the most effective antibacterial agent to date. Penicillin production was quickly scaled up and available in quantity to treat Allied soldiers wounded on D-Day. As production was increased, the price dropped from nearly
priceless in 1940, to $20 per dose in July 1943, to $0.55 per dose by 1946.
Fleming accidentally discovered it while experimenting with mold and bacteria.
Penicillin antibiotics were discovered in 1928 by Alexander Fleming. Penicillin was used since then to fight staph and strep bacterium that were previously deadly.
