In 1938 a wallet manufacturer called the E.H. Ferree company had a genius idea: to show people just how well cards would fit in the wallet, by using a placeholder. The social security card they used was fake in almost all ways but one: The social security number on it was real. It belonged to the secretary of the company’s Vice President and Treasurer, a woman named Mrs. Hilda Schrader Whitcher. The wallet was sold all over the US in Woolworth stores. And soon after it hit the shelves, people started using that social security number as their own.
