Jacqueline Mars Biography: Life, Career, Family, and Net Worth

Jacqueline Badger Mars is an American heiress, former corporate executive, and philanthropist best known as a one-third owner of Mars, Incorporated — the family company behind M&M’s, Snickers, Milky Way, and Pedigree pet food. Born on October 10, 1939, she is the daughter of Forrest Mars Sr. and granddaughter of company founder Franklin Clarence “Frank” Mars. As of 2026, she ranks among the world’s wealthiest women, with an estimated net worth in the $40–50 billion range depending on the valuation source.

Quick Facts Table

Early Life and Education

Jacqueline Mars was born into one of America’s most prominent — and most private — business families. Her father, Forrest Mars Sr., transformed the confectionery business his own father Frank Mars had founded in 1911 into a global consumer goods empire. Growing up, she developed a lifelong passion for equestrian sports, competing in horse shows during her youth, an interest she has maintained through her ownership of horse farms in Virginia to this day.

For her schooling, Mars attended Miss Hall’s School, a private boarding school in Pittsfield, Massachusetts. She went on to Bryn Mawr College in Pennsylvania, a highly selective women’s liberal arts college, graduating in 1961 with a degree in anthropology. This academic grounding in the humanities — rather than business or finance — is notable, since it shaped a career path that combined selective corporate involvement with a strong emphasis on governance, culture, and philanthropy rather than day-to-day operational control alone.

Career Journey: From Family Heiress to Corporate Executive

How Did Jacqueline Mars Become Involved in Mars, Incorporated?

Unlike many heirs who never take on formal roles inside a family business, Jacqueline Mars actively worked at Mars, Incorporated for nearly two decades.

• 1969: Forrest Mars Sr. stepped down from day-to-day management of the company, and control passed largely to Jacqueline’s brothers, John and Forrest Jr.
• 1982: Jacqueline Mars formally joined Mars, Incorporated, taking on the role of Food Product Group President — giving her direct operational responsibility rather than a purely symbolic ownership stake.
• 1982–2001: She spent much of her time working closely with the Mars Foundation, the company’s philanthropic arm, while also contributing to product and business strategy.
• 2001: She retired from active, day-to-day operations at the company.
• Post-2001–2016: She continued to serve on the company’s board of directors well after her operational retirement, stepping down from the board in 2016.

Throughout this period, Mars Incorporated itself expanded well beyond candy — moving into pet care with brands such as Pedigree, Whiskas, and later Royal Canin, and into packaged foods with products like Uncle Ben’s rice (now Ben’s Original). The 2008 acquisition of the Wrigley Company added chewing gum brands like Orbit and Juicy Fruit to the portfolio, and the company’s late-2025 acquisition of snack maker Kellanova further expanded its reach into snack foods.

Major Achievements and Notable Work

Jacqueline Mars’s contributions extend across business, philanthropy, and cultural stewardship:

1. Corporate leadership: Served as Food Product Group President at Mars, Incorporated (1982–2001) and remained on the company’s board until 2016, distinguishing her from purely passive heirs.
2. Pet care expansion: Contributed during a period when Mars diversified heavily into pet nutrition and veterinary services — a segment that today accounts for roughly half of the company’s revenue.
3. Philanthropy: Long-time supporter of the League of Conservation Voters, the National Air and Space Museum, and the Washington Performing Arts Society.
4. Arts and culture leadership: Chairman Emeritus of the Washington National Opera’s board of directors; board member of the National Sporting Library and Fine Arts Museum.
5. Heritage recognition: Received the inaugural Heritage Award from the Foundation for the National Archives in 2011.
6. Major gifts: Donated $1.25 million in 2021 to help house the sculpture “Angels Unawares” at The Catholic University of America, and gifted $10 million toward undergraduate scholarships at her alma mater, Bryn Mawr College, in March 2026.
7. Equestrian philanthropy: Benefactor of the US Equestrian Team Foundation’s Jacqueline B. Mars Competition & Training Grant, which supports the training of American riders.

Personal Life

Is Jacqueline Mars Married?

Jacqueline Mars has been married twice and is currently divorced. She married David H. Badger in 1961, and the couple had three children — Alexandra, Stephen, and Christa Badger — before divorcing in 1984. She later married Harold “Hank” Vogel in 1986; the couple lived in Bedminster, New Jersey, before divorcing in 1994.

Her son, Stephen Badger, has remained closely tied to the family business and has served in leadership roles connected to Mars, Incorporated’s board.

Mars keeps an unusually low public profile for someone of her wealth, rarely giving interviews. She resides in The Plains, in Northern Virginia’s horse country, where she is known for her involvement in equestrian sports and land conservation, including ownership of a working organic farm protected under a conservation easement.

The 2013 Car Accident

In October 2013, at age 74, Mars was involved in a serious car accident on U.S. Route 50 in Aldie, Virginia, near her home. Her vehicle crossed the highway’s center line and collided with a minivan carrying six passengers; one person died at the scene, and another passenger, who was pregnant, subsequently miscarried. Mars later told a witness she had fallen asleep at the wheel. She pleaded guilty to a misdemeanor charge of reckless driving; toxicology tests found no drugs, alcohol, or medications in her system that could explain a blackout.

Net Worth and Business Influence

How Much Is Jacqueline Mars Worth?

Jacqueline Mars’s fortune comes almost entirely from her roughly one-third ownership stake in Mars, Incorporated, a privately held company that does not disclose detailed financials. Because of this, net worth estimates vary noticeably between sources:

• Forbes estimated her fortune at approximately $38.3–38.5 billion in 2023–2024, placing her among the top wealthiest women globally.
• The Bloomberg Billionaires Index has placed her net worth closer to $46–47 billion in more recent estimates.
• Some 2026 estimates place her fortune in a broader $40–50 billion range, reflecting Mars Incorporated’s continued revenue growth — the company reported sales exceeding $54 billion in 2024 — and its expansion through acquisitions such as Kellanova.

In June 2019, Forbes named her the wealthiest resident of Virginia. She has also been consistently ranked among the top 20–25 richest individuals in the United States and among the five richest women in the world.

Legacy and Current Status

Jacqueline Mars represents a rare combination among ultra-wealthy heirs: sustained operational involvement in the family business, followed by a long second act centered on governance, cultural philanthropy, and land conservation. Her career illustrates how the Mars family has preserved control of one of the world’s largest privately held companies across generations, while she personally has built a distinct public identity around the arts, equestrian sports, and historic preservation in Virginia.

As of 2026, she remains an active philanthropist and shareholder, continuing to make major gifts — including her recent multi-million-dollar donation to Bryn Mawr College — while maintaining her characteristically private, low-profile lifestyle away from the media spotlight that typically follows billionaires of her stature.
