Alexander Fleming span>
Alexander Fleming was born on August 6 in 1881 in the county of Ayrshire in Scotland, in a large family farmer. When he was seven years old, his father died, and Alexander, along with his older brother began to handle all the affairs of the farm itself. In 1900, he joined the London Scottish Regiment with the intention to participate in the Boer War, but he did not, because the war was over.
Alexander Fleming graduated from medical school in 1906 and became a Fellow of the Royal College surgeons. In the story of Alexander Fleming, the discoverer came as two important substances — lysozyme and penicillin.
Both discoveries were made by him in 1920, and both — by accident. In the laboratory, where Fleming studied the bacteria, he accidentally sneezed. And after a few days, he noticed that there where to hit a drop of saliva, bacteria were killed. Thus was discovered lysozyme — an enzyme that destroys some of the harmful bacteria without damaging tissue.
The second discovery he made a few years later. He noted that in a petri dish with bacteria, staphylococcus grew mold, which destroyed the bacteria. From the material molds Fleming identified the substance that produces such destruction — penicillin. This opened the historically first antibiotic.
So sloppiness of Alexander Fleming, where he was known among his colleagues have served science. Fleming's work on penicillin release continued by other researchers (Howard Florey and Ernst Boris Chain), and the mass production of the antibiotic was established in the years of the Second World War.
For this discovery, Fleming, Florey and Chain were awarded the 1945 Nobel Prize in Physiology or Medicine.
scientist died March 11 in 1955 in London of a heart attack.
