You’ve probably seen the name Ada Lovelace on a tote bag or a "Women in STEM" poster. She's usually framed as this Victorian lady who just sort of "invented" computer science in a vacuum. But honestly? The real story is way messier, more intellectual, and—if we're being real—a lot more impressive than the simplified version we get in history books.
She wasn't just a "math person." She was the daughter of the "mad, bad, and dangerous to know" poet Lord Byron. Her mother, Annabella Milbanke, was so terrified Ada would inherit her father's erratic poetic temperament that she basically forced the girl into a grueling regime of logic and mathematics. It was an 1800s version of a "Tiger Mom" move, meant to suppress the imagination.
It didn't work.
Instead, Ada combined the two. She called it "poetical science." This wasn't about dry sums. It was about seeing how numbers could describe the very fabric of the world. When she met Charles Babbage and his "Analytical Engine," she didn't just see a calculator. She saw a machine that could, potentially, compose music or create graphics.
She saw the future.
The Babbage Connection and the "Note G" Myth
People love to argue about whether Ada Lovelace actually wrote the first code. Critics like Bruce Collier have historically tried to downplay her role, suggesting she was more of a "hype woman" for Babbage’s inventions rather than a technical architect.
They’re wrong.
In 1842, Ada translated an article by Italian mathematician Luigi Menabrea about Babbage’s Analytical Engine. But she didn't just translate it; she added her own "Notes" that ended up being three times longer than the original paper.
In "Note G," she outlines an algorithm for the machine to calculate Bernoulli numbers.
It’s precise. It’s sequenced. It’s a computer program.

While Babbage had scribbled down bits of code before, Ada’s work was the first published, comprehensive demonstration of a looping sequence of instructions. It wasn't just a calculation; it was an architecture for how machines should "think." She understood that if a machine could manipulate symbols, and those symbols represented something other than quantities (like musical notes or letters), then the machine could manipulate anything.
That's the leap. That is the birth of the computer age.
Why Her "Poetical Science" Actually Matters
Most historians focus on the math, but we need to talk about her mindset. Ada had this weird, brilliant ability to bridge the gap between the physical hardware and the metaphysical potential of technology.
She lived in a world of gears and steam.
Yet, she wrote about the Analytical Engine "weaving algebraic patterns just as the Jacquard loom weaves flowers and leaves." She wasn't just being flowery. She was making a direct technical connection to the punch-card system used in French weaving looms, which would eventually become the basis for early IBM computing.
The Struggle with Victorian Reality
Life wasn't all diagrams and tea. Ada’s health was kind of a disaster. She dealt with chronic pain, probably aggravated by the restrictive social expectations of a Countess. She gambled. Hard. She tried to develop a mathematical system for winning at the horse races, which—spoiler alert—didn't work and left her in significant debt.
There’s a human vulnerability there that people often scrub away to make her a perfect "girlboss" icon. But the gambling and the intensity were part of that same high-functioning, restless brain that figured out the Bernoulli algorithm. She was a gambler in her science, too.

She was also doing all this while raising three children and navigating a marriage to William King-Noel, the Earl of Lovelace. He was actually pretty supportive, which was rare for the time, but the domestic drain on her energy was real.
What Modern Tech Owes to Lovelace
If you look at how we use AI or generative art today, you’re looking at Ada Lovelace’s legacy. She explicitly discussed the idea of whether a machine could be truly "original."
She wrote: "The Analytical Engine has no pretensions whatever to originate anything. It can do whatever we know how to order it to perform."
This is still a massive debate in 2026. Can an LLM actually "create," or is it just following the "Notes" we’ve given it? Ada was asking these questions before electricity was even a standard utility. She defined the boundaries of artificial intelligence before the term "intelligence" was even applied to machines.
The Tragic Ending
Ada died at just 36, the same age as her father. Uterine cancer took her, and the medical treatments of the day—lots of bloodletting—probably made it worse.
For a long time, she was a footnote.
It wasn't until the 1950s that B.V. Bowden republished her notes and the computing world went, "Wait, this lady knew exactly what she was talking about." In 1980, the U.S. Department of Defense named a high-level programming language "Ada" in her honor.
How to Apply the "Lovelace Method" Today
You don't need to be a Victorian Countess to think like Ada. Her approach to the world is actually a blueprint for modern innovation.
Combine "Poetical" with "Practical"
Don't just learn the syntax of a language (whether it's Python or a human language). Look for the metaphor. If you're building a tool, ask: "What does this represent in the real world?" Innovation usually happens at the intersection of two unrelated fields.
Document the "Why," Not Just the "How"
Ada’s fame comes from her Notes, not just the translation. When you work on projects, the value often lies in your commentary and your vision for where the technology could go, rather than just the final product.
Acknowledge Your Hardware Limitations
Ada knew the Analytical Engine might never be built in her lifetime (it wasn't). She worked for the ideal of the machine anyway. If you're working on something that feels ahead of its time, keep building the "software" for it. The hardware eventually catches up.
Audit Your Influences
Ada's mother tried to excise the "Byronic" poetry from her, but it was that very poetic streak that allowed her to see the beauty in the math. Don't hide your "non-technical" hobbies. Your interest in music, art, or even gambling might be the exact thing that gives you a unique edge in a technical field.
To truly honor her legacy, we have to stop treating her like a mascot and start treating her like the rigorous, flawed, and visionary mathematician she was. She didn't just write a program; she imagined a digital world before a single wire was ever crossed.
Next Steps for Deepening Your Knowledge:
- Read the Primary Source: Find a digitized copy of "Sketch of the Analytical Engine Invented by Charles Babbage, with Notes by the Translator." Specifically, skip to Note G.
- Visit the Science Museum: If you're ever in London, they have the prototype segments of the Difference Engine. Seeing the physical gears makes Ada's abstract thinking feel much more grounded.
- Explore the "Ada" Language: Check out the documentation for the Ada programming language. It's still used today in high-stakes environments like aviation and space flight because of its extreme reliability—a fitting tribute to her precision.
