One day a poor Scottish farmer, whose name was Fleming, was trying to make a living for his family. Suddenly he heard a cry for help. It was coming from a boy nearby. He dropped his instruments and ran to the boy. The boystuck in a swamp and only half of him was seen already. He was struggling to free himself but he couldn't. He was in panic and screamed loudly. Farmer Fleming saved the boy from a slow death.
The next day a rich carriage came up to the Scotsman's place. An elegantly dressed man got out and introduced himself as the father of the boy who Fleming had saved. "I want to repay you," said the man.
"You saved тУ son's life'"
"No, I can't take payment for what I
did," the Scottish farmer replied. At that moment the farmer's own son
came to the door of the family house.
"Is that your son?" the man asked.
"Yes," the farmer replied proudly.
"I'll do the following then. Let me take him and give him a good education. If the boy is like his father he'll grow to a man you can be proud of."
And he did that. In time, Fleming's son graduated from St Mary's Hospital Medical School in London, and became known throughout the world as Sir Alexander Fleming, the discoverer of penicillin /,peni'silin/.
Years later that man's son was close to death from pneumonia. He was saved by penicillin. His name was Sir Winston Churchill.
