The Litany
In the mid-1960s, in a buff-colored conference room somewhere inside the Mars candy factory in Chicago, a sixty-year-old man with a gleaming scalp and an English suit with unfashionably wide lapels dropped to his knees at the head of a long table and began to pray. "I pray for Milky Way," he said. "I pray for Snickers." The assembled executives — men accustomed to the orderly rhythms of a closely held, profitable company — did not know whether their new boss was performing, losing his mind, or revealing something fundamental about how power would work in this building from now on. It was all three. Forrest Edward Mars Sr. had waited more than thirty years to run the company his father had founded, had been exiled with $50,000 and a candy recipe, had built and lost and rebuilt fortunes across two continents, and now he was finally in command of the family business, kneeling on a conference room floor, performing devotion to chocolate bars as if they were deities — which, in the Mars cosmology, they essentially were.
The prayer was theatre but the theology was real. Every member of the organization, Forrest believed, must be united in a coordinated drive toward a single objective: profit through faith in the product. Not shareholders. Not quarterly guidance. Not board sentiment. The product. This was the creed of a man who had studied at the Nestlé factory in Vevey, Switzerland, who considered management "applying mathematics to economic problems," who thought through operating methods to the finest detail and codified them in charts and tables. Woe, as Fortune put it in 1967, betide any executive who wavered on the well-marked path to profitability.
Six decades later, the company built on that strange litany generates an estimated $50 billion or more in annual revenue, employs over 140,000 people across more than 70 countries, manufactures five of the ten best-selling candy bars in America, operates more than 3,000 veterinary hospitals, and is attempting to absorb Kellanova — the Cheez-It and Pringles empire — in a $35.9 billion deal that would make Mars one of the two or three largest packaged food companies on earth. It remains 100% family-owned, has never been public, has never issued a bond with public covenants, has never held an earnings call. The Mars family — whose combined fortune exceeds $140 billion — is so aggressively private that when the chairman of Nestlé once visited the company's squat, rust-colored, windowless headquarters in McLean, Virginia, he thought he was at the wrong building. Only about 80 people work there. Locals have called it the Kremlin.
This is a company that does 200 million consumer transactions a day and has the public profile of a witness protection participant. The paradox at its core — maniacal operational intensity married to almost pathological secrecy, relentless global ambition housed in the most modest corporate headquarters imaginable, a family dynasty that has survived four generations without a single public scandal or hostile takeover or IPO — is not incidental to the business. It is the business. Mars Inc. is the proof case for what happens when you remove every external incentive except the product, the margin, and the century-long time horizon.

The Exile and the Empire
To understand Mars, you have to understand the fracture. Not the corporate strategy or the Five Principles or the Kellanova deal — the fracture.
Franklin Clarence Mars was born in 1883 in Hancock, Minnesota, a small town on the prairie where his family ran a grist mill. He contracted polio as a child, which left him with a permanent limp and kept him out of school for long stretches. His mother taught him to hand-dip chocolates at the kitchen stove. That was his education: sugar, cocoa butter, the physics of tempering. He would spend two decades failing — a series of candy ventures in Minneapolis, Tacoma, and back again that produced nothing lasting — before finally, in 1923, at age forty, producing the Milky Way bar. Frank Mars had a genius insight, borrowed from the malted milkshake: use nougat whipped with malt flavoring as a base, layer it with caramel, and coat the whole thing in chocolate. The nougat was cheaper than solid chocolate by weight but tasted more indulgent. The bar was enormous for its price. Sales exploded. By 1924, Mars was selling $800,000 worth of Milky Way bars. By 1929, he'd moved the company to a lavish new factory on Oak Park Avenue in Chicago — a country-club-style operation with open doors for visitors, terrazzo floors, and the feel of a chocolate Versailles.
His son, Forrest, had a different origin story and a different temperament. Born in 1904, raised largely by his maternal grandparents in Saskatchewan after Frank's first marriage collapsed, Forrest was essentially abandoned by his father and reconstructed himself through force of will. He studied industrial engineering at Yale. He was brash, brilliant, combative, and constitutionally incapable of deference. When he rejoined his father's company in the early 1930s, the collision was immediate. Forrest wanted to expand into Canada, to modernize operations, to think globally. Frank was content. He'd gone from polio and poverty to palatial factory; what more was there to want? The argument — variously described as a business dispute and a family explosion — ended in 1932 with Frank giving Forrest $50,000 in cash, the foreign rights to the Milky Way recipe, and, in the immortal formulation, "instructions to go away."
Forrest went. He went to Switzerland, where he studied chocolate manufacturing at Nestlé. He went to England, where he set up a one-room factory and created the Mars Bar — a creamier, sweeter variant of the Milky Way, adapted to European palates, marketed not as an indulgence but as a "food chocolate" in a post-Depression culture that frowned on sweets. "It is more than a sweet, it is a food; the eggs, the large amount of milk and butter, the malted milk, all combined form a nutritious tonic," read the wrapper text. By the mid-1930s, Mars Ltd. was one of the largest candy companies in the United Kingdom. Forrest also launched Petfoods Ltd. in Britain, which would eventually become the foundation of the pet care empire — Pedigree, Whiskas — that today generates roughly half of Mars Inc.'s revenue.
His listeners, without knowing it, were being introduced to a basic tenet of Forrest Mars's management system: all members of an organization must be united in a coordinated drive to a single objective — profit — through faith in the company's leadership and product.
Frank Mars died in 1934. Control of the Chicago company passed to others in the family, and Forrest was largely frozen out. He would not gain control of the original Mars, Inc. until the mid-1960s, more than three decades after his exile. In those thirty years, he built a parallel empire that was, by some measures, several times larger than his father's company. When the merger finally happened — Forrest's Food Manufacturers, Inc. absorbing the old Mars, Inc. under the Mars name — Forrest was sixty years old, and the combined entity had sales Fortune estimated at over $350 million. In 2025 dollars, that's well north of $3 billion. And it was just the beginning.
The Candy That Doesn't Melt in Your Hands
The M&M story is, in many ways, the Mars Inc. origin myth — the moment where exile, observation, and scientific management converged to produce one of the most recognizable consumer products in human history.
In 1937, during the Spanish Civil War, Forrest Mars observed soldiers eating chocolate pellets coated in a hard candy shell. The shell prevented melting. It was a solution to a real physical problem — chocolate degrades in heat — disguised as a confection. Forrest saw immediately that this was a product concept, not just a candy. He returned to the United States and, in 1941, partnered with Bruce Murrie, the son of Hershey president William Murrie, to form M&M Ltd. The "M&M" stood for Mars and Murrie. The Hershey connection was strategic: it guaranteed a supply of chocolate during wartime rationing, when Hershey had the largest allocation of cocoa in the country due to its military contracts.
M&Ms launched as a product perfectly suited for soldiers — portable, heat-resistant, calorie-dense — and the U.S. military became the first major customer. When the war ended and soldiers came home, they brought the taste with them. Forrest eventually bought out Bruce Murrie's 20% stake and took sole ownership. The product's evolution from there — the introduction of peanut M&Ms in 1954, the "melts in your mouth, not in your hand" slogan, the character marketing that turned colored candies into globally recognized mascots — was the work of decades. But the core insight was Forrest's, born on a Spanish battlefield, scaled through military logistics, and protected by a patented candy-shell process that competitors found nearly impossible to replicate with the same consistency.
What made M&Ms strategically significant was not just the product but the business model it revealed. Forrest understood that confectionery margins lived or died on manufacturing precision. A candy bar that was 0.5 grams overweight on every unit at a production volume of millions per day represented an enormous leak of profitability. He became obsessed — genuinely, pathologically obsessed — with manufacturing efficiency, waste reduction, and quality control. The M&M factory at Hackettstown, New Jersey, where workers in hard hats and white coveralls scurried through production lines, became a temple of scientific management applied to sugar.

The Religion of the Five Principles
When Forrest Mars finally consolidated power over the combined Mars, Inc. in the mid-1960s, he did something unusual for a company of its scale: he codified a belief system. Not a mission statement — those are marketing artifacts. A belief system, one that would function as an operating constitution across every geography, every product line, every generation of family and professional management.
The Five Principles of Mars are:
Quality,
Responsibility,
Mutuality,
Efficiency, and
Freedom. They sound, on first reading, like the kind of corporate boilerplate you'd find laminated on the wall of any Fortune 500 cafeteria. They are not. At Mars, the Five Principles function more like religious law — invoked in operational decision-making, used to resolve strategic disputes, referenced in conversations the way a constitutional lawyer cites precedent. Quality means the consumer comes first, always. Responsibility means every associate is personally accountable for outcomes, with no corporate bureaucracy to hide behind. Mutuality means every relationship — with suppliers, customers, communities, the planet — must generate shared benefit. Efficiency means that waste is not just undesirable but morally wrong, a violation of stewardship. Freedom means the company must remain financially independent — no debt, no public markets, no external owners who might compromise long-term thinking for short-term returns.
That last principle — Freedom — is the one that explains nearly everything about Mars's strategic trajectory. The refusal to go public, to issue equity, to take on meaningful long-term debt, has constrained the company in obvious ways (it cannot raise capital as cheaply or as quickly as public competitors) while granting it something almost no company of its size possesses: genuine long-term optionality. Mars can make a $35.9 billion acquisition and negotiate it without an activist investor breathing down its neck. It can invest $1 billion in emissions reduction without a quarterly earnings miss triggering a stock selloff. It can wait thirty years for a market to mature — as it did with pet care — without anyone demanding to see the five-year IRR.
The ability to be secretive is one of the finest benefits of having a private company. Privacy at times today seems like a relic of the non-media past, but it is a legal right — morally and ethically proper and even desirable — and a key to healthy, normal living.
The Five Principles also manifest in distinctly eccentric operational practices. Mars has no executive offices — not because of some Silicon Valley open-plan affectation, but because Forrest believed that private offices created information asymmetry and hierarchy. Everyone sits at desks. Everyone punches a time clock — including, historically, the Mars family members who worked in the business. Associates who arrive late lose 10% of their daily bonus. There are no executive dining rooms. There are no reserved parking spaces. The company matches 10–30% bonuses for performance, calibrated to specific quality and efficiency metrics. Joel Glenn Brenner, in
The Emperors of Chocolate, describes a culture that is simultaneously egalitarian and brutally meritocratic — a workplace where the CEO eats in the same cafeteria and the janitor can be fired for failing to meet a cleanliness standard. Jan Pottker's
Crisis in Candyland documents the more turbulent underside: the family feuds, the autocratic management style, the fear that Forrest's genius could curdle into control.
The tension is instructive. The Five Principles create a culture of extraordinary operational discipline — Mars factories are legendarily clean, Mars supply chains are legendarily efficient, Mars quality standards are legendarily consistent — but they also create a culture of conformity, insularity, and occasionally paralyzing risk-aversion. For decades, the company was slow to innovate on new product forms, preferring to invest in the perfection of existing brands rather than the uncertainty of new ones. The principle of Freedom, taken to its logical extreme, made Mars allergic to acquisitions for most of its history — a stance it has dramatically reversed in the past two decades.
The Pet Care [Pivot](/mental-models/pivot) No One Noticed
Here is the fact that surprises nearly everyone who encounters Mars Inc. for the first time: it is not primarily a candy company. It is a pet company that also makes candy.
The pet care division — encompassing brands like Pedigree, Whiskas, Royal Canin, Iams, Nutro, Sheba, Cesar, and Temptations — generates roughly half of Mars's total revenue. Royal Canin alone, acquired in 2001, is a premium pet nutrition brand with the margin profile and customer loyalty of a luxury goods house. But the real strategic inflection came not from pet food but from pet health. Mars has quietly assembled the largest network of veterinary practices in the United States — and possibly the world — through a series of acquisitions including Banfield Pet Hospital (acquired 2007, now operating approximately 1,000 clinics inside PetSmart stores), BluePearl (specialty and emergency veterinary care), VCA (acquired in a bidding war with other suitors), and AniCura (the largest chain of veterinary hospitals in Europe, with operations across roughly a dozen countries). By 2024, Mars operated more than 3,000 veterinary hospitals globally.
Think about what this means structurally. Mars doesn't just sell pet food; it owns the veterinary relationship. A dog owner who brings their pet to a Banfield clinic for a wellness exam receives a recommendation for Royal Canin or Science Diet (also a Hills/Mars brand in some markets) — a closed loop between care and nutrition that no competitor can easily replicate. The same pet might eat Pedigree from PetSmart, see a Banfield vet inside PetSmart, and receive a prescription diet recommended by that vet. It's vertical integration applied not to a supply chain but to a customer relationship.
The strategy is, from a pure business standpoint, brilliant. Pet care is the rare consumer category that is recession-resistant (people feed their pets before they feed themselves in many cases), has high recurring revenue (kibble is consumable, vet visits are annual), and is structurally growing as pet ownership rates climb globally and spend-per-pet increases in developed markets. Mars positioned itself at every node of this ecosystem decades before "ecosystem strategy" became a consulting buzzword.
It also raises questions that Mars would prefer not to answer publicly. The consolidation of veterinary care under a company that also sells pet food creates inherent conflicts of interest. Should the company that profits from selling pet nutrition also control the veterinary advice that determines what pets eat? Mars has maintained that its veterinary operations are editorially independent, but the structural incentive is obvious, and critics — including some independent veterinarians — have raised concerns about the corporatization of animal medicine.
Wrigley: The $23 Billion Impulse Buy
For most of its history, Mars grew organically. The company's culture, shaped by Forrest's obsession with operational control, was suspicious of acquisitions — they introduced cultural contamination, foreign processes, someone else's problems. The acquisition of Uncle Ben's Rice in the 1940s was an exception, and a small one. Mars preferred to build.
Then, in 2008, Mars did something that stunned the packaged food industry: it acquired the Wm. Wrigley Jr. Company for approximately $23 billion, with financing assistance from
Warren Buffett's Berkshire Hathaway, which provided a $4.4 billion subordinated note and took a minority equity stake. The deal gave Mars the world's leading chewing gum business — Juicy Fruit, Doublemint, Extra, Orbit, 5 Gum — plus Skittles, Starburst, and Lifesavers, which Wrigley had itself acquired from Kraft just a few years earlier.
The Wrigley deal was significant for three reasons. First, it marked Mars's transformation from a company that made things to a company that also bought things. Second, it demonstrated that Mars, despite its allergy to external capital, was willing to bring in a partner — Buffett, specifically — when the prize was large enough. The Berkshire relationship was carefully structured: Buffett got a preferred return on his note and a minority equity position, not a board seat or operational control. Freedom, as the Fifth Principle demanded, was preserved. Third, the deal made Mars the undisputed global leader in confectionery, pushing past Nestlé and Mondelez in total candy and gum market share.
The Wrigley integration revealed both the strengths and limitations of the Mars operating system. Mars's relentless efficiency culture was applied to Wrigley's manufacturing and distribution, extracting significant cost synergies. But the cultural integration was reportedly difficult — Wrigley's more relaxed, marketing-driven culture chafed against Mars's engineering-driven asceticism. The gum category itself, which had seemed like a reliable annuity stream in 2008, has since declined as consumers shifted away from gum toward other snack and confectionery formats. The strategic logic was sound. The timing, at least for the gum business, was imperfect.
The Generational Transfer Machine
Mars Inc. has survived four generations of family ownership without the catastrophic succession crises that have destroyed or diluted countless family businesses. This is not an accident. It is the result of a deliberately engineered governance architecture, one that separates family ownership from family management with a rigor that most family enterprises never achieve.
Forrest Mars Sr. retired from active management in the late 1960s, handing day-to-day operations to his sons, Forrest Jr. and John, and his daughter, Jacqueline. The second generation — the three children — ran the company as co-presidents, a triumvirate structure that was unusual and, by most corporate governance standards, unstable. But it worked, in part because Forrest Sr. had instilled in all three children the same fanatical commitment to the Five Principles and in part because the company's extraordinary profitability reduced the incentive for fratricidal conflict. When you're splitting billions, the marginal utility of grabbing a larger share diminishes.
The third generation — including Victoria Mars, Stephen Badger, and Frank Mars (among others) — took a different approach. Rather than inserting themselves into operational roles, the family professionalized management, appointing non-family CEOs while retaining board control and 100% ownership. Paul Michaels served as CEO from 2004 to 2014. Grant Reid followed from 2014 to 2022. Poul Weihrauch, a Danish executive who had spent decades inside Mars's pet care and confectionery divisions, became CEO in September 2022. None of them are family members.
Victoria Mars, who served as board chair, articulated the philosophy explicitly: the family's role is stewardship, not management. Family members must earn their way into the business — there is no entitlement to a position — and the board includes independent directors who provide external perspective. The Mars family also created a family council to manage ownership issues separately from business strategy, reducing the likelihood that cousin feuds or inheritance disputes would contaminate operations.
We'd like to think we think in generations and not just in quarters. And because of our ownership, we carry the name of our owners on the door, we have an obligation to make sure that we behave well in society.
The result is a company that moves like a dynasty and thinks like an endowment. The Mars family, whose collective net worth Forbes estimates at over $140 billion, has never sold a share. There is no liquidity event on the horizon. No SPAC. No dual-class IPO. The wealth compounds inside the company's balance sheet and is distributed through dividends that the family reinvests, saves, or donates according to personal preference. The family is so private — no interviews since the early 1990s, photographs strictly prohibited at the McLean headquarters, a general aversion to appearing on any list or at any social event — that they function almost as the antimatter to their products' omnipresence. Everyone has eaten a Snickers. Almost no one has met a Mars.
Kellanova and the $36 Billion Bet on Salt
On August 14, 2024, Mars announced its intention to acquire Kellanova — the snacking-focused company spun out of the Kellogg Company in October 2023 — for $83.50 per share, valuing the transaction at approximately $35.9 billion. The premium was 33% above Kellanova's 52-week high. The implied EBITDA multiple was 16.4x, rich by packaged food standards but not unprecedented for a transformative deal. Mars CEO Poul Weihrauch had invited Kellanova CEO Steve Cahillane to lunch at Skadden Arps's Chicago office on May 31, 2024 — the choice of a law firm's conference room rather than a restaurant signaling that this was business, not courtship. The deal moved from first contact to signed agreement in roughly ten weeks. For a $36 billion transaction, that is extraordinarily fast.
The strategic logic is straightforward, at least on paper. Mars is dominant in sweet snacking — chocolate, candy, gum — but has almost no presence in salty and savory snacks. Kellanova owns Pringles, Cheez-Its, Town House crackers, Eggo waffles, MorningStar Farms, and Rice Krispies Treats. Approximately 50% of Kellanova's net sales come from outside North America, giving Mars expanded international distribution in categories it currently doesn't serve. The combined company would generate approximately $63 billion in revenue, placing it alongside Unilever as the second-largest packaged food company in the world, behind only Nestlé.
The deal also represents an implicit hedge against two existential threats facing Mars's confectionery business: the GLP-1 revolution (Ozempic, Wegovy, and their successors, which suppress appetite and are already affecting snack food demand at the margins) and the long-term secular trend away from sugar. Salty snacks, while hardly health food, carry a different perception profile than chocolate bars — they're savory, they're shareable, they're positioned as accompaniments to meals rather than pure indulgences. By diversifying into Kellanova's portfolio, Mars reduces its dependence on a single consumption occasion.
By late June 2025, the U.S. Federal Trade Commission cleared the merger, determining that it wouldn't threaten competition. As of mid-2025, European Commission review remains the final regulatory hurdle, with Mars and Kellanova expecting the deal to close towards the end of 2025. If it does, Mars will have completed the largest acquisition in its 113-year history — larger than Wrigley by more than $12 billion — and will have transformed itself from a confectionery-and-pet-care company into a diversified food conglomerate spanning sweet snacks, salty snacks, pet nutrition, pet health care, and food staples. The question is whether the Mars operating system — designed for chocolates, calibrated for pet food, stress-tested on chewing gum — can absorb a $36 billion acquisition in a category it has never operated in, at a premium it has never paid, without losing the operational discipline that made it Mars.
The Sustainability Wager
In late 2023, Mars CFO Claus Aagaard announced a $1 billion investment over three years to reduce the company's emissions by 50% by 2030 and reach net zero by 2050. Roughly 90% of Mars's greenhouse gas emissions are Scope 3 — occurring in the extended value chain, primarily in agricultural production of cocoa, palm oil, and dairy — which means Mars cannot decarbonize by putting solar panels on its factories alone. It has to change how farmers farm.
The company launched an initiative called Supplier Leadership on Climate Transition, working with its largest suppliers to shift electricity consumption to renewables. It claims its palm oil supply chain is now deforestation-free and has committed to making its cocoa supply chain deforestation-free by the end of 2025. Approximately 60% of its global electricity already comes from wind and solar. Aagaard described the ambition as "integrating this sustainability or climate agenda into the core of the business," complete with periodic carbon reporting alongside financial reporting.
The cynical reading is that this is corporate ESG theater — a privately held company making unverifiable claims about supply chain emissions without the disclosure requirements that public companies face. The more charitable reading, and probably the more accurate one, is that Mars's private ownership structure actually makes it more capable of pursuing long-term sustainability investments, not less. There is no quarterly earnings call where an analyst can ask why the company is spending $1 billion on emissions instead of returning capital to shareholders. There are no shareholders to return capital to, except the family, and the family has decided that generational stewardship includes the planet.
The deeper tension, though, is not about carbon accounting. It's about cocoa. Mars has been accused — alongside every major chocolate company — of profiting from supply chains that rely on child labor in West Africa. A 2023 CBS News investigation alleged that children in Ghana were harvesting cocoa destined for M&Ms and Snickers, that field supervisors falsified compliance paperwork, and that Mars's 2025 deadline for full child labor remediation was further from achievement than the company publicly projected. Mars responded that it "unequivocally condemns the use of child labor" and is "urgently investigating" the claims. Over 65% of its West African cocoa supply is covered by a Child Labor Monitoring and Remediation System. A lawsuit filed in Washington, D.C., in 2023 targets Mars, Cargill, and Mondelez for alleged negligent supervision and consumer fraud related to child labor.
This is the irreducible contradiction at the heart of Mars's sustainability narrative: a company that invests $1 billion in emissions reduction while its cocoa supply chain — the foundation of its most iconic products — remains entangled with labor practices that no amount of corporate reporting can fully verify or control. The company's commitment to the principle of Mutuality is genuine, in the sense that real money is being spent and real organizational resources are being deployed. But mutuality at the corporate level and exploitation at the farm level can coexist, and the structural incentives of commodity agriculture in West Africa ensure that they will, until the economics of cocoa farming fundamentally change.
The Operator's Paradox
Poul Weihrauch became Mars CEO in September 2022, having spent nearly three decades inside the company, including leadership roles in pet care and confectionery across multiple geographies. He is Danish, methodical, and disarmingly candid about the tensions inherent in running a $50 billion private company in an era that rewards public spectacle. "All marathons are run in a sprint," he told the Harvard Business Review in December 2025. "You have to do both" — the long-term generational vision and the short-term operational execution. "There's no doubt that at certain times it's great not to be under the scrutiny of the stock exchange," he added, before noting that Mars faces the same competitive pressures as any publicly traded peer.
Weihrauch inherited a company in exceptional strategic shape and a world of exceptional strategic uncertainty. The confectionery business faces cocoa price inflation — cocoa futures hit historic highs in 2024 — GLP-1 demand destruction, shifting consumer preferences toward healthier snacking, and the relentless expansion of private-label alternatives. The pet care business, while structurally advantaged, faces growing scrutiny over veterinary consolidation and margin pressure from premium competitors and DTC brands. The Kellanova acquisition, if completed, will require integrating 20,000+ employees across dozens of countries into a culture designed around chocolate bars and dog food.
The Mars operating system was built for a world of fewer, bigger, simpler bets — a handful of iconic brands manufactured with extraordinary efficiency and distributed through every retail channel on earth. The world Weihrauch faces demands agility, digital marketing, e-commerce, sustainability transparency, and the ability to compete in categories (salty snacks, veterinary telehealth, plant-based proteins) that Forrest Mars Sr. could not have imagined from his knees on that conference room floor.
The Kremlin on Dolley Madison Boulevard
The company's headquarters in McLean, Virginia — a few miles past the CIA campus on Dolley Madison Boulevard, which is itself a detail too perfect for fiction — is a squat, two-story, rust-colored building with a PRIVATE PROPERTY sign, no corporate identification, meager windows, and a locked front door. Inside, upstairs, hang portraits of the Mars family. Photographs of these portraits are strictly prohibited. When Fortune visited, a reporter noted that the company's public relations team operated at a hair-trigger level of alertness, snapping to attention at any mention of a family member and ruling questions out of order with the reflexive efficiency of a Secret Service detail.
Eighty people work in this building, overseeing a company that is larger than McDonald's, larger than Starbucks, larger than General Mills. The disconnect is deliberate. The modesty signals a set of beliefs about what a company is for: not for the aggrandizement of its owners, not for the performance of corporate power, but for the relentless, anonymous, generation-spanning accumulation of value through products that people buy every single day without once thinking about who made them.
Forrest Mars Sr. died in 1999 at the age of 95. His fortune at death was estimated at over $4 billion. His three children — Forrest Jr., John, and Jacqueline — became among the twenty richest people in America. They gave almost no interviews. They attended almost no public events. They owned the company that makes M&Ms, Snickers, Pedigree, Whiskas, Uncle Ben's, Skittles, Orbit, and a hundred other products that collectively touch billions of lives per week, and they chose to be invisible.
On any given day in 2025, somewhere in the world, a child is eating an M&M that was manufactured to tolerances measured in fractions of a gram, in a factory so clean you could eat off the floor — which, given the product, is quite literally the point — by a company whose owners' faces you have never seen, whose stock you cannot buy, and whose conference rooms still echo, faintly, with a prayer for Snickers.
