The Founding Father Who Turned $4,000 Into Millions— 200 Years After He Died

The Founding Father Who Turned $4,000 Into Millions— 200 Years After He Died

Benjamin Franklin spent his life chasing a good return. So perhaps it’s fitting that his single most audacious investment didn’t pay off until two centuries after he was buried.

The idea wasn’t even originally his. A few years before his death, a French writer published a gentle parody of Franklin’s relentless American optimism, imagining a character who left a small sum in his will to grow untouched for 500 years. Most people would have laughed it off. Franklin wrote back to thank the man — and announced he’d decided to actually do a version of it.

Less than a year before he died in 1790, Franklin added a codicil — a formal amendment — to his will. In it, he left £1,000 (roughly $4,000 at the time) each to the cities of Boston, where he was born, and Philadelphia, where he made his fortune. But he didn’t simply hand the cities the cash. He wrote a remarkably detailed set of instructions, because what he was really betting on was the quiet, relentless power of compound interest.

The money was to be loaned out in small amounts, at 5% interest, to young married tradesmen under 25 who had finished their apprenticeships — a nod to the loans that had launched Franklin’s own printing career. None of it could be spent for 100 years. At that mark, the cities could use about three-quarters of the fund on public works (Boston put its share toward a trade school), while the remaining quarter kept compounding for a second full century. Franklin even added a competitive twist: if one city declined the gift, the other would receive the entire amount.

It worked, more or less as designed. After the first hundred years, Boston’s fund had grown to roughly $400,000. By 1990 — exactly 200 years after his death — Boston’s trust was worth around $4.5 million and Philadelphia’s about $2 million, ultimately flowing to institutions that still bear his name. The totals fell short of Franklin’s rosiest projections, mostly because two centuries of trustee fees, taxes, and the occasional legal squabble took their cut. But the core lesson held: a small sum, structured carefully and left alone, can become a fortune.

Behind the showmanship is a genuinely useful idea. Franklin used ordinary estate-planning tools — a will, a codicil, and a pair of trusts — to direct exactly how his money would be managed and spent long after he was gone. Those same tools are available to anyone, no founding-father status required.

What’s a will?

A will is a legal document that states who gets your assets when you die, who should care for your minor children, and who you trust to carry out those instructions (the “executor”). A codicil, like the one Franklin used, is simply a formal amendment to an existing will — a way to update your wishes without rewriting the whole thing. If you die without any will at all, the law uses a default formula to distribute your estate, and that formula rarely matches what you would have chosen.

Most wills go through probate, the court-supervised process of validating the document and distributing assets. It can be slow, public, and expensive, depending on where you live.

What’s a trust?

A trust is a legal arrangement where you (the “grantor”) place assets under the management of a trustee for the benefit of someone (a “beneficiary”). You set the rules — who receives what, when, and under what conditions — and the trustee is legally bound to follow them, sometimes for generations.

Franklin’s 200-year funds are an extreme example of exactly that durability.

A revocable living trust can also let assets skip probate, passing directly and privately to your

beneficiaries. There are limits on how long you can keep controlling assets, though: a doctrine called the rule against perpetuities generally prevents truly endless trusts. Franklin’s 200-year horizon was unusual precisely because charitable trusts get more leeway than private ones.

Why bother with either?

A few of the most common benefits:

• Control. You decide who gets what, when, and how — with conditions and timing if you want

them — instead of leaving it to a default legal formula.

• Protecting your family. A will lets you name guardians for minor children. A trust can release

money gradually rather than all at once.

• Avoiding probate. Trusts can spare your heirs a slow, public court process.

• Privacy. Wills typically become public record. Trusts usually stay private.

• Leaving a legacy. Charitable trusts let you support causes — schools, scholarships, your

community — long after you’re gone, just as Franklin did.

• Flexibility. Tools like codicils let you update your plan as life changes, without starting over.

The takeaway

Franklin’s 200-year experiment is remembered as a curiosity — a Founding Father playing the long game from beyond the grave. But the mechanics weren’t magic. He wrote his wishes down, amended them when inspiration struck, and structured them through trusts with clear rules and named people to carry them out. You don’t need two centuries or a printing empire to do the same. Whatever your wishes are, the worst version is the one no one ever wrote down.
