He qualified with distinction in 1906 and began research at St. Mary's under Sir Almroth Wright, a pioneer in vaccine therapy. He gained M.B., B.S., (London), with Gold Medal in 1908, and became a lecturer at St. Mary's until 1914. He served throughout World War I as a captain in the Army Medical Corps.
He was elected Professor of the School in 1928 and Emeritus Professor of Bacteriology, University of London in 1948.
Early in his medical life, Fleming became interested in the natural bacterial action of the blood and in antiseptics. He was able to continue his studies throughout his military career and on demobilization he settled to work on antibacterial substances which would not be toxic to animal tissues. In 1921, he discovered in «tissues and secretions» an important bacteriolytic substance which he named Lysozyme. About this time, he devised sensitivity titration methods and assays in human blood and other body fluids, which he subsequently used for the titration of penicillin. In 1928, while working on influenza virus, he observed that mould had developed accidently on a staphylococcus culture plate and that the mould had created a bacteria-free circle around itself. He was inspired to further experiment and he found that a mould culture prevented growth of staphylococci, even when diluted 800 times. He named the active substance penicillin.

Mold spores are extremely tiny, about the size of dust particles. They exist just about everywhere -- you are most likely breathing in a few of them into your lungs right this second. It just so happens that a few penicillum mold spores got into Fleming's petri dish; who knows how or when.
Alexandra Fleming was a scientist who discovered the anti biotic penicillin. he actually discovered it by an accident. but it was used to cure the army in w.w2 as in world war 2.So he got famous by inventing something by accident!
Heterozygous (got it from my 9th grade biology textbook)
The inside of a typical cell is posotive in respect to the outside. I got this out of my biology book.
Alexander Fleming got married in Lochfield, Scotland.
Alexander Fleming got married in Lochfield, Scotland.
Alexander Fleming grew up in Scotland then moved to London and got his Doctor degree and her invented penicillin.
Around his early 20's
It wasn't really an invention; it was more of an accidental discovery. Alexander Fleming is credited with the discovery. On September 28, 1928, he noticed that a Petri dish that was accidentally left open got moldy, and there was an area around the mold where the culture in the dish would not grow. However, others had written about the antibacterial properties of Penicillium before Fleming.

john Fleming did not discover penicillin but sir Alexander Fleming did.sir alexander Fleming was a Scottish scientist . he usually put lids on the dishes,but one day he forgot some time later he noticed that some bacteria in these dishes had died. Fleming investigated this he found that the bacteria had been killed by a mould(a type of fungus)called penicillium,which must have got into the dishes that were left uncovered.
Alexander Fleming discovered penicillin, he left it in a petri dish for 2 weeks whilst he was on holiday when the got back there was a ring shape of mould, he then tested it on 8 mice and 4 were given penicillin they lived, four weren't and they died! To me this answer is good as it helped four mice survive, it also helped soldiers get better in world war 1!
