Margaret Cargill had a problem most people dream about.
She was worth $1.8 billion. But she didn't want anyone to know.
Born in 1920, Margaret inherited a slice of one of America's biggest family fortunes. Her great-grandfather had started a little grain company in 1865. By the time Margaret grew up, Cargill Inc. was making over $100 billion a year.
The Cargill family had more billionaires than any other family in America. Fourteen of them.
Margaret was one of eight heirs to this massive fortune. She could have bought anything. Done anything. Gone anywhere.
Instead, she bought art supplies and went camping.
While her cousins ran the family business, Margaret couldn't have cared less about corporate meetings or profit margins. She cared about pottery. About Native American textiles. About the way light hit a piece of handwoven silk.
She took her time with everything. Didn't finish college until she was 34. Moved to Southern California where she split time between three simple places - a house near the beach, a cabin in the mountains, and visits to the desert.
Well into her 70s, Margaret was still loading up her RV and heading to the pine forests with friends. She drove herself everywhere in an old Jeep.
When a financial advisor flew out to meet her in 1993, she called his hotel. "I'll pick you up in half an hour. Be out front."
He waited on the curb, expecting a limousine. Instead, a woman in her 70s pulled up in a beat-up Jeep and yelled, "Climb in!"
Her advisor later said, "Money really wasn't important to her. If she had enough, she had enough. She wasn't buying diamonds. She was buying a piece of artwork made by a Hopi woman."
But Margaret had billions of dollars. And a very clear idea of what to do with them.
Around 1990, she started giving it away. Quietly.
She sent anonymous cashier's checks to the American Red Cross. Created fake foundations with made-up names to hide her identity. Showed up at organizations calling herself just "Margaret" and disappeared before anyone could ask questions.
Over 15 years, she gave away more than $200 million. The Nature Conservancy. The Smithsonian. Animal shelters. Music schools. Elder care facilities.
Nobody knew where the money was coming from.
Bishop John Chane was struggling to keep his San Diego cathedral running when a stranger walked into his office. She'd never made an appointment. Never even called.
"I understand you're having a hard time with the budget," she said. "I'd like to help."
She handed him a cashier's check. He assumed it was maybe fifty bucks from a kind church member.
"Who should I say this is from?" he asked.
"Just say it was an angel."
After she left, he unfolded the check. $50,000.
That mystery angel kept coming back. It took ten years before the bishop learned her real name.
The same thing happened everywhere Margaret gave.
When the San Diego Humane Society needed $1.57 million to finish their new building, their mystery donor asked one simple question: "How much do you need?"
"You'll have your check next week," she said.
The beautiful thing about Margaret's secret giving was what she did next. She showed up to enjoy what she'd created.
When the National Museum of the American Indian opened in Washington D.C., Margaret was there in the crowd. Wandering through exhibits. Watching families discover Native American art for the first time. Thrilled that she'd helped make it happen.
Nobody at the opening knew the quiet woman in comfortable shoes had donated millions to build the place.
At building dedications and charity events she'd funded, Margaret would slip in the back. She'd watch the speeches thanking anonymous donors. She'd see the joy on people's faces as they experienced something her money had made possible.
Then she'd slip out, completely unknown.
"She was thrilled to be incognito at events that were basically honoring her," one charity director remembered.
Margaret died on August 1, 2006, at her California home. She was 85.
Only then did the world learn her name.
She'd never married. No children. Her whole life had been art and friends and camping trips and quiet giving.
She left everything to charity. Every single share of Cargill stock she owned.
But here's the problem - you can't just sell billions of dollars of a private company overnight. The lawyers and family members spent five years figuring it out.
Finally, in 2011, they made it work. Margaret's 17.5% stake in Cargill was worth over $6 billion.
When the Chronicle of Philanthropy released their list of America's biggest donors in 2012, a dead woman topped the list.
Margaret Cargill - gone for six years - had given more than anyone else in America that year.
Today, the Margaret A. Cargill Philanthropies has over $9 billion. It's one of the ten largest charitable foundations in America. They've given away more than $3 billion since her death.
The Red Cross still gets money from Margaret. So does the Nature Conservancy. The Smithsonian. Animal shelters. Music programs. All the causes she cared about will be funded forever.
The woman who drove a Jeep and slept in an RV created a giving machine that will save lives for generations.
Margaret believed giving wasn't about the giver. She didn't want buildings named after her. Didn't want recognition or awards or thank-you dinners.
She wanted to sit in the back row at a museum opening, watching kids discover art for the first time. She wanted to know she'd made it possible. And she wanted no one else to know.
She wanted to be an angel.
For 85 years, that's exactly what she was.
