Tuesday, October 13, 2026 | Ada Lovelace Day

What if the history of artificial intelligence has been missing some of its most important characters?

Imagine spending forty years working with computers.

You witness the personal computer revolution. You watch the internet transform civilization. You experience artificial intelligence becoming part of everyday life.

And then, one October afternoon, you discover a woman who imagined that computing machines might someday create music.

In 1843.

Her name was Ada Lovelace.

And she is only the beginning of this Rabbit Hole.

The White Rabbit opens an enormous Victorian door.

WHITE RABBIT: "Professor! Professor! I've found a lady who understood computers before computers existed!"

PROFESSOR PARALLAX: "A profound paradox, my peeps! How can one understand a future that hasn't happened?"

WHITE RABBIT: "Apparently, Professor, by imagining it!"

In nineteenth-century Britain, mathematician Charles Babbage was developing designs for the Analytical Engine, a remarkable mechanical calculating machine.

It was an extraordinarily ambitious invention, never completed during his lifetime.

But Ada Lovelace looked at Babbage's proposed machinery and imagined something beyond arithmetic.

If numbers could represent musical notes, symbols, or other forms of information, then a programmable machine might manipulate those things too.

In 1843, she published extensive notes accompanying her translation of Luigi Menabrea's account of the Analytical Engine.

Those notes included an elaborate procedure for calculating Bernoulli numbers.

Today, Ada is frequently celebrated as the first computer programmer.

Historians debate the precise boundaries of that description because Babbage had developed unpublished procedures of his own. What is beyond serious dispute is that Ada published a remarkable early account of programmable computation and articulated possibilities extending beyond numerical calculation.

She understood that a machine capable of manipulating numbers might eventually manipulate representations of the world.

Letters.

Patterns.

Symbols.

Music.

Nearly two centuries later, those ideas resonate throughout digital technology.

And that raises a remarkable question.

When we ask an AI system to compose music, generate an image, or transform language, are we witnessing something Ada had already begun to imagine?

Not the technology itself. She had no modern computer, neural network, or generative AI model.

But she understood a foundational possibility.

Information need not remain imprisoned within its original form.

Before the word computer meant an electronic machine, it often referred to a human being employed to perform mathematical calculations.

And many of those human computers were women.

At Harvard College Observatory, women analyzed photographic plates, cataloged stars, and helped transform astronomy.

Consider three remarkable figures.

Williamina Fleming helped develop stellar classification methods and identified important astronomical objects.

Annie Jump Cannon developed a stellar classification approach that became fundamental to astronomy.

Henrietta Swan Leavitt discovered the relationship between the periods and intrinsic luminosities of Cepheid variable stars, providing a crucial tool for measuring cosmic distances.

Their work required observation, classification, mathematical reasoning, and extraordinary attention to patterns.

Today, automated systems perform immense quantities of data classification and analysis.

But before algorithms were processing astronomical data at scale, these women were discovering the universe through human intelligence.

They weren't merely recording the heavens. They were helping humanity learn how to measure them.

And some of their contributions received far less public recognition than their scientific importance warranted.

The White Rabbit opens another door.

WHITE RABBIT: "Professor! This room is full of wires!"

PARALLAX: "Good heavens! We've arrived at the twentieth century!"

During World War II, a revolutionary electronic computer called ENIAC was developed in the United States.

Six women became its original programmers:

They worked out how to program an unprecedented machine, mastering its operations and developing techniques for organizing and debugging computations.

Yet their pioneering contributions were often treated as clerical work rather than recognized as major technical achievements.

Only decades later did their work begin receiving the broader recognition it deserved.

Consider the irony.

The machinery became famous.

The women who made it perform complicated tasks remained comparatively obscure.

A computer without a program is not the same thing as a functioning computational solution.

Engineering the hardware mattered enormously.

So did the intelligence required to make it useful.

Both deserve a place in history.

In the American space program, mathematician Katherine Johnson performed calculations that helped put astronauts into space.

Working in an era shaped by both racial segregation and discrimination against women, Johnson developed a reputation for exceptional mathematical ability.

When John Glenn prepared for his historic 1962 orbital mission, he wanted Johnson to verify the computer-generated trajectory calculations.

Think about that moment.

Electronic computing was becoming essential to spaceflight.

Yet an astronaut preparing to ride a rocket into orbit wanted reassurance from a human mathematician.

The machine could calculate. The human expert could check whether the calculation deserved trust.

That principle remains astonishingly relevant today.

AI systems can generate convincing answers.

But convincing is not the same as correct.

Human understanding remains essential to evaluating outputs, identifying errors, and accepting responsibility for decisions.

Katherine Johnson's story is therefore not merely a historical celebration.

It is a lesson in the relationship between human expertise and computational power.

And today's Rabbit Hole takes a particularly poignant turn.

Margaret Hamilton, pioneering software engineer and leader of Apollo flight-software development, died on September 30, 2026, at age 90.

She led the team at MIT responsible for software essential to the Apollo missions.

During Apollo 11's lunar landing in July 1969, the guidance computer issued alarms as it struggled with its workload.

The software's priority-handling capabilities helped the mission continue despite those alarms.

Hamilton and her colleagues had helped develop systems designed to withstand unexpected conditions.

They understood that software wasn't merely an accessory to engineering.

Software was engineering.

The reliability of a machine could depend upon invisible instructions written by people who anticipated what might go wrong.

Margaret Hamilton's legacy reminds us that sophisticated technological systems depend not only on creative ambition, but also on meticulous preparation.

And now, just days after her passing, we celebrate Ada Lovelace Day.

One woman helped imagine the extraordinary possibilities of programmable machinery.

Another helped build the software that carried humanity to the Moon.

What an extraordinary historical connection.

Why have so many women's contributions to computing required rediscovery?

There is no single explanation.

Educational exclusion played a role.

Institutional discrimination played a role.

So did cultural assumptions about whose work counted as invention, engineering, leadership, or scientific discovery.

In many organizations, women performed essential technical work without receiving the professional status available to male colleagues.

And historical storytelling often celebrated the most visible inventors, company founders, or institutional leaders while neglecting the teams that made their achievements possible.

But accuracy matters here too.

We should not erase Babbage to celebrate Ada.

We should not diminish hardware engineering to celebrate programming.

And we should not assume that every overlooked contribution resulted from deliberate suppression.

The goal is not to replace one incomplete history with another. It is to recover a fuller one.

One in which women and men receive recognition proportionate to what they actually contributed.

Today's AI revolution makes this history newly urgent.

Who develops our intelligent systems?

Whose perspectives shape the training data?

Who decides what counts as a successful result?

Who receives credit for discoveries?

And who is left out of the conversation?

These questions extend beyond gender.

They concern economic opportunity, geography, race, disability, education, and access to technology.

A technology capable of serving billions should not be imagined solely through the experiences of a privileged few.

That's one reason the histories of Ada Lovelace, the Harvard Computers, the ENIAC programmers, Katherine Johnson, and Margaret Hamilton matter.

They remind us that humanity's technological achievements have always depended upon a wider range of minds than popular histories sometimes acknowledge.

And that brings us to a principle for the AI era:

Intelligence should be recognized wherever it appears. Opportunity should not depend upon belonging to the right club.

At the end of a long corridor, the White Rabbit discovers a door covered in names.

WHITE RABBIT: "Professor, there are thousands of names here!"

PARALLAX: "Scientists, mathematicians, inventors, programmers, teachers, engineers..."

WHITE RABBIT: "Why haven't I heard of most of them?"

Professor Parallax studies the inscription above the doorway.

PARALLAX: "A profound paradox, my peeps! We have machines capable of remembering almost everything, yet humanity keeps forgetting the people who made them possible!"

The Rabbit opens the door.

Beyond it lies an enormous library.

There is no single inventor standing at its center.

Instead, there are countless people, each contributing a page, an equation, a design, an idea, a question.

Some names are famous.

Many are not.

Together, they have written the story of computing.

WHITE RABBIT: "Professor, is this the history of artificial intelligence?"

PARALLAX: "No, my dear Rabbit. This is the history of human intelligence that brought us here."

Ada Lovelace did not build a modern AI system.

The Harvard astronomers did not train neural networks.

The ENIAC programmers did not invent today's software industry alone.

Katherine Johnson did not replace electronic computers.

Margaret Hamilton did not accomplish the Apollo missions by herself.

But each contributed something indispensable to the larger human journey.

And perhaps the most important lesson is this:

The history of technology is not the story of a handful of geniuses acting alone.

It is the cumulative achievement of generations of thinkers, builders, experimenters, critics, and creators.

As AI becomes more capable, our responsibility is not merely to build better machines.

It is also to build a future in which human contributions are recognized, opportunity is more widely shared, and creativity is not reserved for an exclusive few.

The future of intelligence should not repeat the exclusions of its past.

Whose contributions to science, technology, art, or invention did you discover only recently, and whose stories do you think deserve to be told next?

We'd love to hear your discoveries.
