years he worked in a shipping company. When he was
about twenty years old,an uncle died and left him some money.
At his elder brother's advice, he took an entrance
examination for medical school. He passed brilliantly
and joined St. Mary's Hospital in London. There he met
Sir Almroth Wright and that meeting changed the
course of his life. When he graduated, he joined Wright's
laboratory staff instead of going into private practice as
he had intended.
During the First World War, he served in the Royal
Army Medical Corps and was shocked by what he saw
in France. Hundreds of wounded soldiers, with bacteria crawling in their wounds ,were brought to his hospital. But there was little he could do for them as the antiseptics in use then were not effective for deep wounds. He was horrified by the suffering and the numerous deaths, but Fleming was a determined man full of courage and he vowed to discover something that would kill these bacteria and save lives.
After the war he continued his research. For years he toiled on;then in September 1928 he made one of the greatest discoveries of all time. He had been growing colonies of bacteria in flat,open dishes. A few days later he saw that mould had settled in one of the dishes. However, he did not throw away the dish; instead he examined it and saw that no bacteria grow near the mould. “Had the mould killed the bacteria?” he asked himself.
