Alexander Fleming
Alexander Fleming came from a Scottish family of farmers. He was born in August, 1881, the youngest of eight children. He began to do to school when he was five. His lessons came easily to him, he had a good memory and very intelligent.
It was quite by chance that he came into contact with the man who was to affect his whole life. It was a famous bacteriologist. Fleming became interested in antibacterial medicaments.
After the army service, during which he was able to make studies of the problem of infection Fleming returned to laboratory work.
One day Fleming's assistant brought him a plate on which a colony of bacteria was growing. it was some mould.
Fleming looked at the plate again and saw that the microbes all round the mould were gone. He was a real researcher. For over fifteen years he was solving that problem. He understood the importance of what had happened and began to study it. He put some of the mould on other plates and grew more colonies of it. Then he discovered that this new product killed microbes. He named it Penicillin. Fleming was finding out more and more about penicillin. He found that the mould began to produce penicillin on the fifth day.
Fleming's dream was to find a new method for producing penicillin. At last his dream came true. A new product was tried on different bacteria. The researchers tried it on animals and had good results. Penicillin had not yet been used on man. Then one day in 1942 Fleming made his own first experiment. His friend was very ill After several injections his was saved.
Later on during World War II this medicine saved a great many lives. It was a great triumph. In 1945 he was given the Nobel Prize for medicine.
He died on the 11th of March 1955 in London and was buried in St.Paul's Cathedral.
