Doublemint is a variety of chewing gum made by the Wrigley Company.  According to early advertisements it is "double strength" peppermint flavored and was launched in the United States in 1914. Related brands are Juicy Fruit and Wrigley's Spearmint.

The first set of women to portray the Doublemint Twins were sisters Marie and Mildred Maier of Silverhill, Alabama.  

The first Doublemint Twins to appear on television came along in 1959.  The role belonged to 21-year-old twins, Jayne and Joan Knoerzer from Hammond, Indiana.

Jayne and Joan Knoerzer

Jayne and Joan were singers who had no real interest in acting though they signed a contract with Wrigley in the late 50s. Wrigley put their musical background to work and let them cut a 1/3 EP record called "Double Your Pleasure" written by Arthur Meyerhoff.  The song is the official Doublemint theme song!  Wrigley put the identical twins in ads showing them doing things like riding bikes, playing tennis and other fun activities together.  Strangely, the company wouldn't let them chew gum in the ads.  They spent every moment of their life promoting the gum and made great money doing so. They lived in a beautiful apartment and bought a mink coat for their mother. They lost the gig when Joan became pregnant in 1963 as they were no longer identical twins.  Not much is known about the twins today.  They both got married and Jayne now lives in Beverly Hills, California.

The Knoerzer's replacements were Chicago natives, Terrie and Jennie Frankel in late 60s.  Like their predecessors, they were great musicians who often performed for patients.  They signed on with Wrigley in 1963 at the age of 13. When they turned 18, they auditioned for the USO and resigned their role as the Doublemint Twins.  Over the next few years, they performed for the troops in Vietnam, Hawaii and various other locations. Both went on to have very successful careers in Hollywood. Terrie was a screenwriter, producer and composer who served on the boards of numerous prestigious institutes.  Jennie and Terrie got David Letterman his first gig writing for The Tonight Show and wrote Dr. Phil's first pilot.  They also wrote many successful movies over the years. Later in life, they became New York Time best-selling authors.  Jennie passed away in 2008 and Terrie currently resides in Sedona, Arizona. 

Terrie and Jennie Frankel

"Doublemint Twins" included June and Patricia Mackrell through the 1970s.  They had also been the Toni Twins for Toni Home Permanent which used the slogan "Which twin has the Toni?" though they spoke for many brand products. There's not much information on what the Mackrell Twins did later in life.  After they left the gig as the Doublemint Twins they faded into obscurity. 

Patricia and Priscilla Barnstable got their start as Doublemint Twins though what they were most famous for was modeling in Playboy magazine later in their career. Today, they are known for their massive Kentucky Derby Gala they throw almost every year! 

Patricia and Priscilla Barnstable

Identical twins Patricia and Priscilla Barnstable were so popular as the Doublemint Twins that they were later asked to pose for Playboy magazine.  Although they were wholesome and cute as chewing gum models, the Barnstable twins projected an entirely different image during their Playboy photo shoot.  

Dian and Denise Gallup became another set of Doublemint Twins through the years and  benefited from the prestige of being the spokepersons for the iconic gum brand.  They acted in small roles on shows like The A-Team, Hill Street Blues and Who's the Boss.

The Segal Doublemint Twins

Liz and Jean Segal were cast for the role in the 1980s.  Their role was short-lived, but they used it as a stepping-stone to act in their own TV show, "Double Trouble". Later on Liz acted in the movie Howard the Duck and enjoyed a successful career as a TV writer for the show, Sons of Anarchy which starred her sister, Katey and was created by her brother-in-law, Kurt Sutter.

Linda and Lisa Yokubinas

Linda and Lisa were the longest running Doublemint Twins therefore were some of the most recognizable twins.  From small beginnings in small-town Illinois, they were cast in 1985 to bring Doublemint into the new era.  This partnership was extremely benefical for the two as it ended up as a career for them.  They became stars over the next six-decades.  Over ten years they starred in six commercials for the iconic gum.  You might remember the one where they lost their hats next to a swimming pool.  Six commercials don't seem like a lot but they were earning up to $30,000 in residual checks for a period based just on reruns. Another perk of the gig was the travel.  What could be better than shooting commercials around the world with your best friend?

Ten years of playing twins created issues down the road for them.  When they no longer worked as the Doublemint Twins, casting directors typecast the as twins.  With no work, except together, the twins began to resent each other. They didn't speak for many years, but have since mended their fences. 

Brittany and Cynthia Daniel 

After the Yokubinas long reign came to an end, Brittany and Cynthia Daniel became the Doublemint Twins.  They were the first set of twins to be fraternal, not identical.  Their reign was shorter than their predecessors due to the fact they landed a sweet job as the stars of Sweet Valley High a year later.  After the show ended a few years later, Cynthia Daniel retired from acting to become a photographer. The one exception was a cameo on That 80s Show which featured her sister at the time.  Brittany continued acting and had a successful career for the next decade.  

Tia and Tamera Mowry

You may recognize these Doublemint Twins from their hit show, "Sister, Sister".  They were Doublemint Twins during the 1990s.  Some mistakenly believe they were the first black Wrigley spokepersons, but that distinction goes to Sharon Sansaverino and Sheryl Valenti in the 1980s.  The Mowry sisters had arguaby the most successful post-Doublemint acting careers.  

After a long break, Wrigley decided to bring back the Doublemint Twins for the modern era.  In 2005, Nicole and Natalie Garza landed the job.  Their ads mostly consisted of wearing vintage clothes and singing songs about enjoying the simple things as a stark contrast to modern life. 

The Garza Doublemint twins were the last to be featured by Wrigley which has scaled back its gum advertising over the last decade.  The concept has staying power so this might not be the last we see of the beloved Doublemint Twins.
