In 1730, Benjamin Franklin — unmarried at the time — took in an infant boy.
Franklin was just 24 years old.
No official records clearly identify the mother.
In the deeply moralistic society of colonial America, that was scandalous.
The child had been born out of wedlock, and Franklin never publicly revealed the mother’s identity.
Yet Franklin did something remarkable for that era: he acknowledged the child publicly and raised him as his own.
The boy was William Franklin.
Soon after, Benjamin Franklin married Deborah Read, and William grew up in their household. Franklin educated him, mentored him, and exposed him to intellectual life.
William accompanied his father on diplomatic missions, studied law, and moved in elite circles.
Franklin invested in him — intellectually and politically.
In many ways, William was his father’s proudest project.
A Rising Star of the British Empire
Through Benjamin Franklin’s influence and reputation in London, William’s career accelerated.
In 1763, William Franklin was appointed Royal Governor of New Jersey — one of the highest offices in colonial America.
It was a triumph for both father and son.
At the time, Benjamin Franklin himself was still loyal to the British Crown.
He believed the empire could be reformed from within.
William, however, went further.
He believed completely in the empire.
And that difference would eventually tear them apart.
The Revolution That Divided a Family
When tensions rose between the American colonies and Britain, Benjamin Franklin changed.
He watched Parliament impose taxes. He saw colonial grievances dismissed. He attempted diplomacy in London — and failed.
Gradually, he became a revolutionary.
William did not.
As Royal Governor, William remained firmly loyal to King George III.
He believed rebellion would bring chaos and thought the patriots were reckless.
Father and son began arguing in letters.
Franklin tried to persuade him.
William refused.
Then came the breaking point.
Prisoner of the Revolution
In 1776, as war erupted, William Franklin was arrested by revolutionary authorities for supporting Britain.
He was imprisoned in Connecticut under harsh conditions.
Benjamin Franklin did not intervene.
Imagine that.
A father — now one of the most influential revolutionaries in America — did not save his own son from imprisonment.
For William, this was betrayal.
For Benjamin, it was principle.
Franklin believed the cause of liberty transcended blood.
Loyalist Leader in Exile
After being released in a prisoner exchange, William fled to British-controlled New York and later to England.
There, he continued advocating for the British position.
He became a leading Loyalist voice and eventually served in senior legal and advisory roles aligned with British authority in London.
In effect, he became part of the British establishment opposing American independence.
He stood publicly against his father’s cause.
The son had become the embodiment of the side the father was fighting.
The Letter That Closed the Door
Their final correspondence is heartbreaking.
Benjamin wrote to William saying he could forgive many things — but not his political decision to support what he believed was oppression.
William wrote back defending his honor and loyalty to the Crown.
They never reconciled.
Franklin even removed William from his will, leaving him almost nothing.
In one of the most dramatic family fractures in history, a Founding Father effectively disowned his son.
The Funeral Without a Son
The American Revolutionary War lasted eight years, from 1775 to 1783.
Benjamin Franklin helped secure the Treaty of Paris (1783), which officially ended the war.
George Washington became the first President of the United States in 1789.
When Benjamin Franklin died in 1790, around 20,000 people attended his funeral in Philadelphia.
William did not attend.
He was in England.
The distance between them was no longer political.
It was permanent.
What This Story Teaches Us
Benjamin Franklin was rational.
He was strategic.
He was pragmatic.
He valued liberty over loyalty.
He chose principle over family.
William chose loyalty over revolution.
The American Revolution did not only divide colonies.
It divided families.
It divided fathers and sons.
Franklin helped found a nation.
But he lost his heir.
And that may have been the price.
