Alexander Fleming was bom on August 6th, 1881 on Darvel, Scotland. He was one of the eight children in the family. As a boy he showed a strong interest in nature.
Just before his 14th birthday he went to London to live with an older brother, Dr. Thomas Fleming. At 16 he went to work as a clerk for a shipping company.
When Fleming was twenty, an uncle died and left him a small sum of money. Determined to use the money wisely, he asked his brother’s advice. Dr. Flemning suggested that he take an examination for medical college. He took the exam, and he got the highest score. He then began to study at St. Mary’s Hospital in London.
When he completed his medical training, Fleming did not join his brother’s practice as he had earlier intended. He decided to spend the rest of his life as a biologist.
It was in the fall of 1928 that Fleming discovered penicillin, the chemical produced by a mold called Penicillum. But it was two years before anyone attempted to produce pure penicillin in quantity. This was achieved by two other scientists, Howard Florey and Ernst Chain, during World War Ⅱ , in time to save the lives of thousands of wounded soldiers.
In 1945, he, Florey and Chain received the Nobel Prize for medicine.
Alexander Fleming died at the age of 71, on March 11th, 1955.
