SAFETY PIN

 

 

 

SAFETY PIN 
     
One day in 1849 Walter Hunt wanted to pay a fifteen-dollar debt to a friend. So he decided to invent something new.  
From a piece of brass wire about eight inches long, coiled at the center and shielded at one end, he made the first safety pin. He took out a patent on his invention, sold the rights to it for four hundred dollars, paid his friend back and had three hundred eighty-five dollars to spare.  
Then he watched his latest brainstorm go on to become a million dollar money earner for someone else.
