Meet the Mars family, heirs to the Snickers and M&M's candy empire, who spent years avoiding the limelight and are America's third-wealthiest family 'dynasty'

They made the first chocolate nougat, setting the foundation for Milky Way Bars and Snickers. Forrest Sr. fell out with his father; in 1932, he was given the recipe for the Milky Way Bar to start his own business.

Since then, the company has become known for the eponymous Mars Bar, 3 Musketeers, Twix, and M&Ms. More than 400 million M&Ms are produced in the US every day.

The company's secrecy dates back to when Forrest Sr. patented the method for Uncle Ben's rice and American military chiefs tried to overturn the patent to supply troops.

Forrest Sr. reportedly avoided photographers and interviews alike.

However, he did buy a 740-acre farm in Virginia in the 1940s. He and his wife, Audrey, lived apart for a lot of their marriage — she kept a penthouse apartment at The Watergate.

Forrest Sr. has been described as having an "extreme temper," but was separately praised as "one of this century's most brilliant and successful entrepreneurs" by Fortune magazine in 1984.

"He was an iconic leader – dedicated and highly respected," a Mars spokesperson told Business Insider.

Currently, Jacqueline and John co-own, but don't actively manage, Mars Inc. They have the biggest share of the family fortune, with $24 billion each.

They rank on the Forbes 400 along with Forrest Jr.'s four daughters, who have $6 billion each. The collective fortune of all six is $72 billion, making them the third-richest family "dynasty" in the US, according to the Billionaire Bonanza report.

She reportedly listed her estate in New Jersey for $2 million, has a place called Stonehall Farm in Virginia, and maintains her mother's Watergate penthouse. Like her family, Jacqueline maintains privacy.

In 2013, Jacqueline was involved in a car crash in Loudon County. She was driving her Porsche SUV "when her vehicle crossed the center line and hit an eastbound minivan," according to authorities, reported the Washington Post.

"According to authorities, Mars told a witness who went to the scene of the accident that she had fallen asleep while driving," wrote Caitlin Gibson of The Washington Post. "Tests revealed no trace of drugs, alcohol, or medications that could have caused a blackout ... Witnesses said that Mars was not speeding or driving erratically before the accident."

The accident occurred in Loudon County; the driver of the other car lost her unborn son, a passenger died, and other passengers were injured. The victims urged the court not to seek jail time for Jacqueline, who pleaded guilty. She was ordered to pay a $2,500 fine.

"I can't go back in time. I can’t change what happened," Mars, who planned to help the family, said in a statement. "I will always live with the grief and loss caused by this tragedy."

Recently, the company has started to open up about its business to be transparent to consumers and attract talent, Badger told Business Insider.

"For most of our history, in fact ... for 99% of our history, we've chosen not to be in the public eye and we've really wanted our brands to engage consumers. And yet times have changed," Badger said.

Both he and Jacqueline run the Mars Foundation, which donates to educational, environmental, cultural, and health-related causes. The company also has a volunteer program.

Both John and Forrest Jr. inherited their father's tendency to avoid the spotlight. And their father's frugal ways stuck with them: Both brothers reportedly lived in relatively affordable condos.

"When I was growing up it felt very normal," Forrest Jr.'s daughter, Pamela Mars, told Campden FB. "I didn't feel different to anybody else. We did chores around the house, we went to school. We didn't live a different lifestyle to any of my friends."

Victoria, daughter of Forrest Mars Jr., is currently the chairman of the board of directors of Mars Inc. A spokesperson for Mars told Business Insider that there are six rotating positions on the board.

Growing up, Pamela lived in Holland and France for several years before moving back to the US for her father's various Mars Inc. jobs. After graduating from Vassar and a stint working in advertising, Pamela joined the family business as an operations supervisor. She moved up the ranks, and after a sabbatical, became chairman of the board, a position from which she later stepped down.

According to Forbes, Valerie and Marijke both work at Mars and serve on the company's board of directors.

"The Mars company and the family that owns the candy giant have turned secrecy into a way of life," wrote Pottker. Morningstar food analyst Mitchell Howard called Mars a "very, very quiet company."

Nicknamed "the Kremlin," the Mars Inc. headquarters are based in the Virginia suburbs and have been described as "secretive" and "anonymous."

In 2008, Mars Inc. branched out from chocolate to gum when it acquired the Wrigley Jr. Company for $23 billion, and it bought Iams and two other pet food brands in 2014 from Procter & Gamble for close to $2.9 billion.

The $35-billion firm is the country's fifth-largest private business, and it was previously ranked as a best place to work by Fortune magazine.

Mars Inc. can attribute its success to the five principles that Pamela Mars called the bedrock of the company: quality, responsibility, mutuality, efficiency, and freedom.

Jacqueline also supports the US Olympic Equestrian Team and is a trustee of the US Equestrian Team Foundation. She sits on several boards, including the National Sporting Library and Fine Art Museum, the Smithsonian, and the American Prairie Reserve.

According to a Mars spokesperson, she received the first-ever Foundation for the National Archives' "Heritage Award," for her support of the National Archives and other arts and cultural institutions in Washington, DC.

She also played a role merging the Opera with John F. Kennedy Center for the Performing Arts and made a multi-year commitment to support the Washington Performing Arts' programs.

"The family has always believed that the biggest contribution toward the world we want tomorrow is through the good that Mars, Inc. can do every day, and the family reinvests the vast majority of any profit made back into the company," a company spokesperson told Business Insider.

And in 2017, the company made a $1 billion investment in a sustainability program that will contribute to the UN’s Sustainable Development Goals and the Paris Climate Agreement.

But one thing will always remain private: the company itself.

"The philosophy of the family and the philosophy of the business is that it's a family business," Pamela told Campden FB. "More importantly, it's a privately held business and that's the way that we'd like to keep it."
