Answer:

Walter Hunt

Walter Hunt invented the safety pin. He first got the idea for the safety pin while nervously twisting a piece of wire. He was trying to think of something he could do that would allow him to pay off a $15 debt. He patented his safety pin invention in April 1849. He didn’t think the invention would ever amount to much and soon sold the patent for $400. Source: TheInventor.org
