Apparently an inventor named Walter Hunt owed his friend fifteen dollars. He wanted to invent something to make a bit of money to pay his friend back. He invented things a lot but didn't usually make much money off of them. So he invented the safety pin, hoping to make enough to pay his friend. He made four hundred dollars off of his pins! He had plenty of money left over after paying his friend, and became famous for some thing we use daily!
Happy Safety Pin day!
