Alexander Fleming

His name was Fleming, and he was a poor Scottish farmer. One day, while
trying to eke out a living for his family, he heard a cry for help
coming from a nearby bog. He dropped his tools and ran to the bog.
There, mired to his waist in black muck, was a terrified boy, screaming
and struggling to free himself. Farmer Fleming saved the lad from what
could have been a slow
and terrifying death.
The next day, a fancy carriage pulled up to the Scotsman's sparse
surroundings. An elegantly dressed nobleman stepped out and introduced
himself as the father of the boy Farmer Fleming had saved.
"I want to repay you," said the nobleman. "You saved my son's life."
"No, I can't accept payment for what I did," the Scottish farmer
replied, waving off the offer. At that moment, the farmer's own son
came to the door of the family hovel.
"Is that your son?" the nobleman asked. "Yes," the farmer replied
proudly.
"I'll make you a deal. Let me take him and give him a good education.
If the lad is anything like his father, he'll grow to a man you can be
proud of."
And that he did. In time, Farmer Fleming's son graduated from St.
Mary's Hospital Medical School in London, and went on to become known
throughout the world as the noted Sir Alexander Fleming, the discoverer
of Penicillin.
Years afterward, the nobleman's son was stricken with pneumonia.
What saved him? Penicillin.
The name of the nobleman? Lord Randolph Churchill.
His son's name? Sir Winston Churchill.
