“Every twin in America wanted to be part of the Doublemint advertising,” Paul added. All of the applicants were subsequently vetted, including the Knoerzer twins. The president of the chewing gum company at the time, Philip K. Wrigley, was very keen to ensure a wholesome image for his product.
“[Wrigley] wanted to know where the twins lived, did they have a good reputation, and that they didn’t dance on tables or get drunk,” Joan Knoerzer later recalled. For reasons that are unclear, however, the Knoerzer twins weren’t actually allowed to chew gum in any of the advertisements.
From 1959 to 1963, the original Doublemint Twins featured in a series of commercials. And they would also appear at events across the United States to promote the gum in person. “[We could] afford a beautiful apartment and travel and buy our mom a mink coat,” Jayne Knoerzer said.
