The safety pin was the invention of WALTER HUNT. HUNT was a mechanic from New York, whose other inventions include a forerunner of the Winchester repeating rifle, a successful flax spinner, knife sharpener, streetcar bell, hard coal burning stove, artificial stone, road sweeping machinery, velocipedes, ice ploughs and mail making machinery.
In 1834, Walter Hunt built American's first sewing machine, which was also the first eye pointed needle sewing machine. He later lost interest in patenting his sewing machine, because he believed the invention would cause unemployment.
The safety pin was invented while Walter Hunt was twisting a piece of wire, trying to think of something that would help him pay off a fifteen dollar debt. On April 10, 1849, the safety pin was patented. Walter Hunt also thought little of his safety pin as an invention and soon sold the patent for four hundred dollars.
